| CVE-2023-26470 | 1 Xwiki | 1 Xwiki | 2023-11-07 | N/A | 7.5 HIGH |
| XWiki Platform is a generic wiki platform offering runtime services for applications built on top of it. It's possible to make the farm unusable by adding an object to a page with a huge number (e.g. 67108863). Most of the time this will fill the memory allocated to XWiki and make it unusable every time this document is manipulated. This issue has been patched in XWiki 14.0-rc-1. | |||||
| CVE-2023-27479 | 1 Xwiki | 1 Xwiki | 2023-11-07 | N/A | 9.9 CRITICAL |
| XWiki Platform is a generic wiki platform offering runtime services for applications built on top of it. In affected versions any user with view rights can execute arbitrary Groovy, Python or Velocity code in XWiki leading to full access to the XWiki installation. The root cause is improper escaping of UIX parameters. A proof of concept exploit is to log in, add an `XWiki.UIExtensionClass` xobject to the user profile page, with an Extension Parameters content containing `label={{/html}} {{async async="true" cached="false" context="doc.reference"}}{{groovy}}println("Hello " + "from groovy!"){{/groovy}}{{/async}}`. Then, navigating to `PanelsCode.ApplicationsPanelConfigurationSheet` (i.e., `<xwiki-host>/xwiki/bin/view/PanelsCode/ApplicationsPanelConfigurationSheet` where `<xwiki-host>` is the URL of your XWiki installation) should not execute the Groovy script. If it does, you will see `Hello from groovy!` displayed on the screen. This vulnerability has been patched in XWiki 13.10.11, 14.4.7 and 14.10-rc-1. Users are advised to upgrade. For users unable to upgrade the issue can be fixed by editing the `PanelsCode.ApplicationsPanelConfigurationSheet` wiki page and making the same modifications as shown in commit `6de5442f3c`. | |||||
| CVE-2023-26477 | 1 Xwiki | 1 Xwiki | 2023-11-07 | N/A | 9.8 CRITICAL |
| XWiki Platform is a generic wiki platform. Starting in versions 6.3-rc-1 and 6.2.4, it's possible to inject arbitrary wiki syntax including Groovy, Python and Velocity script macros via the `newThemeName` request parameter (URL parameter), in combination with additional parameters. This has been patched in the supported versions 13.10.10, 14.9-rc-1, and 14.4.6. As a workaround, it is possible to edit `FlamingoThemesCode.WebHomeSheet` and manually perform the changes from the patch fixing the issue. | |||||
| CVE-2023-26478 | 1 Xwiki | 1 Xwiki | 2023-11-07 | N/A | 8.1 HIGH |
| XWiki Platform is a generic wiki platform. Starting in version 14.3-rc-1, `org.xwiki.store.script.TemporaryAttachmentsScriptService#uploadTemporaryAttachment` returns an instance of `com.xpn.xwiki.doc.XWikiAttachment`. This class is not supported to be exposed to users without the `programing` right. `com.xpn.xwiki.api.Attachment` should be used instead and takes case of checking the user's rights before performing dangerous operations. This has been patched in versions 14.9-rc-1 and 14.4.6. There are no known workarounds for this issue. | |||||
| CVE-2020-11057 | 1 Xwiki | 1 Xwiki | 2023-11-07 | 9.0 HIGH | 8.8 HIGH |
| In XWiki Platform 7.2 through 11.10.2, registered users without scripting/programming permissions are able to execute python/groovy scripts while editing personal dashboards. This has been fixed 11.3.7 , 11.10.3 and 12.0. | |||||
| CVE-2023-37913 | 1 Xwiki | 1 Xwiki | 2023-11-03 | N/A | 8.8 HIGH |
| XWiki Platform is a generic wiki platform offering runtime services for applications built on top of it. Starting in version 3.5-milestone-1 and prior to versions 14.10.8 and 15.3-rc-1, triggering the office converter with a specially crafted file name allows writing the attachment's content to an attacker-controlled location on the server as long as the Java process has write access to that location. In particular in the combination with attachment moving, a feature introduced in XWiki 14.0, this is easy to reproduce but it also possible to reproduce in versions as old as XWiki 3.5 by uploading the attachment through the REST API which doesn't remove `/` or `\` from the filename. As the mime type of the attachment doesn't matter for the exploitation, this could e.g., be used to replace the `jar`-file of an extension which would allow executing arbitrary Java code and thus impact the confidentiality, integrity and availability of the XWiki installation. This vulnerability has been patched in XWiki 14.10.8 and 15.3RC1. There are no known workarounds apart from disabling the office converter. | |||||
| CVE-2023-45136 | 1 Xwiki | 1 Xwiki | 2023-11-02 | N/A | 9.6 CRITICAL |
| XWiki Platform is a generic wiki platform offering runtime services for applications built on top of it. When document names are validated according to a name strategy (disabled by default), XWiki starting in version 12.0-rc-1 and prior to versions 12.10.12 and 15.5-rc-1 is vulnerable to a reflected cross-site scripting attack in the page creation form. This allows an attacker to execute arbitrary actions with the rights of the user opening the malicious link. Depending on the rights of the user, this may allow remote code execution and full read and write access to the whole XWiki installation. This has been patched in XWiki 14.10.12 and 15.5-rc-1 by adding appropriate escaping. The vulnerable template file `createinline.vm` is part of XWiki's WAR and can be patched by manually applying the changes from the fix. | |||||
| CVE-2023-45134 | 1 Xwiki | 1 Xwiki | 2023-11-02 | N/A | 9.0 CRITICAL |
| XWiki Platform is a generic wiki platform offering runtime services for applications built on top of it. `org.xwiki.platform:xwiki-platform-web` starting in version 3.1-milestone-1 and prior to 13.4-rc-1, `org.xwiki.platform:xwiki-platform-web-templates` prior to versions 14.10.2 and 15.5-rc-1, and `org.xwiki.platform:xwiki-web-standard` starting in version 2.4-milestone-2 and prior to version 3.1-milestone-1 are vulnerable to cross-site scripting. An attacker can create a template provider on any document that is part of the wiki (could be the attacker's user profile) that contains malicious code. This code is executed when this template provider is selected during document creation which can be triggered by sending the user to a URL. For the attacker, the only requirement is to have an account as by default the own user profile is editable. This allows an attacker to execute arbitrary actions with the rights of the user opening the malicious link. Depending on the rights of the user, this may allow remote code execution and full read and write access to the whole XWiki installation. This has been patched in `org.xwiki.platform:xwiki-platform-web` 13.4-rc-1, `org.xwiki.platform:xwiki-platform-web-templates` 14.10.2 and 15.5-rc-1, and `org.xwiki.platform:xwiki-web-standard` 3.1-milestone-1 by adding the appropriate escaping. The vulnerable template file createinline.vm is part of XWiki's WAR and can be patched by manually applying the changes from the fix. | |||||
| CVE-2023-45135 | 1 Xwiki | 1 Xwiki | 2023-11-02 | N/A | 8.0 HIGH |
| XWiki Platform is a generic wiki platform offering runtime services for applications built on top of it. In `org.xwiki.platform:xwiki-platform-web` versions 7.2-milestone-2 until 14.10.12 and `org.xwiki.platform:xwiki-platform-web-templates` prior to versions 14.10.12 and 15.5-rc-1, it is possible to pass a title to the page creation action that isn't displayed at first but then executed in the second step. This can be used by an attacker to trick a victim to execute code, allowing script execution if the victim has script right or remote code execution including full access to the XWiki instance if the victim has programming right. For the attack to work, the attacker needs to convince the victim to visit a link like `<xwiki-host>/xwiki/bin/create/NonExistingSpace/WebHome?title=$services.logging.getLogger(%22foo%22).error(%22Script%20executed!%22)` where `<xwiki-host>` is the URL of the Wiki installation and to then click on the "Create" button on that page. The page looks like a regular XWiki page that the victim would also see when clicking the button to create a page that doesn't exist yet, the malicious code is not displayed anywhere on that page. After clicking the "Create" button, the malicious title would be displayed but at this point, the code has already been executed and the attacker could use this code also to hide the attack, e.g., by redirecting the victim again to the same page with an innocent title. It thus seems plausible that this attack could work if the attacker can place a fake "create page" button on a page which is possible with edit right. This has been patched in `org.xwiki.platform:xwiki-platform-web` version 14.10.12 and `org.xwiki.platform:xwiki-platform-web-templates` versions 14.10.12 and 15.5-rc-1 by displaying the title already in the first step such that the victim can notice the attack before continuing. It is possible to manually patch the modified files from the patch in an existing installation. For the JavaScript change, the minified JavaScript file would need to be obtained from a build of XWiki and replaced accordingly. | |||||
| CVE-2023-37911 | 1 Xwiki | 1 Xwiki | 2023-10-31 | N/A | 6.5 MEDIUM |
| XWiki Platform is a generic wiki platform offering runtime services for applications built on top of it. Starting in version 9.4-rc-1 and prior to versions 14.10.8 and 15.3-rc-1, when a document has been deleted and re-created, it is possible for users with view right on the re-created document but not on the deleted document to view the contents of the deleted document. Such a situation might arise when rights were added to the deleted document. This can be exploited through the diff feature and, partially, through the REST API by using versions such as `deleted:1` (where the number counts the deletions in the wiki and is thus guessable). Given sufficient rights, the attacker can also re-create the deleted document, thus extending the scope to any deleted document as long as the attacker has edit right in the location of the deleted document. This vulnerability has been patched in XWiki 14.10.8 and 15.3 RC1 by properly checking rights when deleted revisions of a document are accessed. The only workaround is to regularly clean deleted documents to minimize the potential exposure. Extra care should be taken when deleting sensitive documents that are protected individually (and not, e.g., by being placed in a protected space) or deleting a protected space as a whole. | |||||
| CVE-2023-37910 | 1 Xwiki | 1 Xwiki | 2023-10-31 | N/A | 8.1 HIGH |
| XWiki Platform is a generic wiki platform offering runtime services for applications built on top of it. Starting with the introduction of attachment move support in version 14.0-rc-1 and prior to versions 14.4.8, 14.10.4, and 15.0-rc-1, an attacker with edit access on any document (can be the user profile which is editable by default) can move any attachment of any other document to this attacker-controlled document. This allows the attacker to access and possibly publish any attachment of which the name is known, regardless if the attacker has view or edit rights on the source document of this attachment. Further, the attachment is deleted from the source document. This vulnerability has been patched in XWiki 14.4.8, 14.10.4, and 15.0 RC1. There is no workaround apart from upgrading to a fixed version. | |||||
| CVE-2023-37909 | 1 Xwiki | 1 Xwiki | 2023-10-31 | N/A | 8.8 HIGH |
| XWiki Platform is a generic wiki platform offering runtime services for applications built on top of it. Starting in version 5.1-rc-1 and prior to versions 14.10.8 and 15.3-rc-1, any user who can edit their own user profile can execute arbitrary script macros including Groovy and Python macros that allow remote code execution including unrestricted read and write access to all wiki contents. This has been patched in XWiki 14.10.8 and 15.3-rc-1 by adding proper escaping. As a workaround, the patch can be manually applied to the document `Menu.UIExtensionSheet`; only three lines need to be changed. | |||||
| CVE-2023-37912 | 1 Xwiki | 1 Xwiki-rendering | 2023-10-31 | N/A | 8.8 HIGH |
| XWiki Rendering is a generic Rendering system that converts textual input in a given syntax into another syntax. Prior to version 14.10.6 of `org.xwiki.platform:xwiki-core-rendering-macro-footnotes` and `org.xwiki.platform:xwiki-rendering-macro-footnotes` and prior to version 15.1-rc-1 of `org.xwiki.platform:xwiki-rendering-macro-footnotes`, the footnote macro executed its content in a potentially different context than the one in which it was defined. In particular in combination with the include macro, this allows privilege escalation from a simple user account in XWiki to programming rights and thus remote code execution, impacting the confidentiality, integrity and availability of the whole XWiki installation. This vulnerability has been patched in XWiki 14.10.6 and 15.1-rc-1. There is no workaround apart from upgrading to a fixed version of the footnote macro. | |||||
| CVE-2023-37908 | 1 Xwiki | 1 Xwiki-rendering | 2023-10-31 | N/A | 9.6 CRITICAL |
| XWiki Rendering is a generic Rendering system that converts textual input in a given syntax into another syntax. The cleaning of attributes during XHTML rendering, introduced in version 14.6-rc-1, allowed the injection of arbitrary HTML code and thus cross-site scripting via invalid attribute names. This can be exploited, e.g., via the link syntax in any content that supports XWiki syntax like comments in XWiki. When a user moves the mouse over a malicious link, the malicious JavaScript code is executed in the context of the user session. When this user is a privileged user who has programming rights, this allows server-side code execution with programming rights, impacting the confidentiality, integrity and availability of the XWiki instance. While this attribute was correctly recognized as not allowed, the attribute was still printed with a prefix `data-xwiki-translated-attribute-` without further cleaning or validation. This problem has been patched in XWiki 14.10.4 and 15.0 RC1 by removing characters not allowed in data attributes and then validating the cleaned attribute again. There are no known workarounds apart from upgrading to a version including the fix. | |||||
| CVE-2023-45144 | 1 Xwiki | 1 Oauth Identity | 2023-10-20 | N/A | 9.6 CRITICAL |
| com.xwiki.identity-oauth:identity-oauth-ui is a package to aid in building identity and service providers based on OAuth authorizations. When a user logs in via the OAuth method, the identityOAuth parameters sent in the GET request is vulnerable to cross site scripting (XSS) and XWiki syntax injection. This allows remote code execution via the groovy macro and thus affects the confidentiality, integrity and availability of the whole XWiki installation. The issue has been fixed in Identity OAuth version 1.6. There are no known workarounds for this vulnerability and users are advised to upgrade. | |||||
| CVE-2023-45138 | 1 Xwiki | 1 Change Request | 2023-10-18 | N/A | 9.6 CRITICAL |
| Change Request is an pplication allowing users to request changes on a wiki without publishing the changes directly. Starting in version 0.11 and prior to version 1.9.2, it's possible for a user without any specific right to perform script injection and remote code execution just by inserting an appropriate title when creating a new Change Request. This vulnerability is particularly critical as Change Request aims at being created by user without any particular rights. The vulnerability has been fixed in Change Request 1.9.2. It's possible to workaround the issue without upgrading by editing the document `ChangeRequest.Code.ChangeRequestSheet` and by performing the same change as in the fix commit. | |||||
| CVE-2023-40176 | 1 Xwiki | 1 Xwiki | 2023-08-29 | N/A | 5.4 MEDIUM |
| XWiki Platform is a generic wiki platform offering runtime services for applications built on top of it. Any registered user can exploit a stored XSS through their user profile by setting the payload as the value of the time zone user preference. Even though the time zone is selected from a drop down (no free text value) it can still be set from JavaScript (using the browser developer tools) or by calling the save URL on the user profile with the right query string. Once the time zone is set it is displayed without escaping which means the payload gets executed for any user that visits the malicious user profile, allowing the attacker to steal information and even gain more access rights (escalation to programming rights). This issue is present since version 4.1M2 when the time zone user preference was introduced. The issue has been fixed in XWiki 14.10.5 and 15.1RC1. | |||||
| CVE-2023-40177 | 1 Xwiki | 1 Xwiki | 2023-08-29 | N/A | 8.8 HIGH |
| XWiki Platform is a generic wiki platform offering runtime services for applications built on top of it. Any registered user can use the content field of their user profile page to execute arbitrary scripts with programming rights, thus effectively performing rights escalation. This issue is present since version 4.3M2 when AppWithinMinutes Application added support for the Content field, allowing any wiki page (including the user profile page) to use its content as an AWM Content field, which has a custom displayer that executes the content with the rights of the ``AppWithinMinutes.Content`` author, rather than the rights of the content author. The vulnerability has been fixed in XWiki 14.10.5 and 15.1RC1. The fix is in the content of the AppWithinMinutes.Content page that defines the custom displayer. By using the ``display`` script service to render the content we make sure that the proper author is used for access rights checks. | |||||
| CVE-2023-37914 | 1 Xwiki | 1 Xwiki | 2023-08-24 | N/A | 8.8 HIGH |
| XWiki Platform is a generic wiki platform offering runtime services for applications built on top of it. Any user who can view `Invitation.WebHome` can execute arbitrary script macros including Groovy and Python macros that allow remote code execution including unrestricted read and write access to all wiki contents. This vulnerability has been patched on XWiki 14.4.8, 15.2-rc-1, and 14.10.6. Users are advised to upgrade. Users unable to upgrade may manually apply the patch on `Invitation.InvitationCommon` and `Invitation.InvitationConfig`, but there are otherwise no known workarounds for this vulnerability. | |||||
| CVE-2023-37462 | 1 Xwiki | 1 Xwiki | 2023-07-27 | N/A | 8.8 HIGH |
| XWiki Platform is a generic wiki platform offering runtime services for applications built on top of it. Improper escaping in the document `SkinsCode.XWikiSkinsSheet` leads to an injection vector from view right on that document to programming rights, or in other words, it is possible to execute arbitrary script macros including Groovy and Python macros that allow remote code execution including unrestricted read and write access to all wiki contents. The attack works by opening a non-existing page with a name crafted to contain a dangerous payload. It is possible to check if an existing installation is vulnerable. See the linked GHSA for instructions on testing an installation. This issue has been patched in XWiki 14.4.8, 14.10.4 and 15.0-rc-1. Users are advised to upgrade. The fix commit `d9c88ddc` can also be applied manually to the impacted document `SkinsCode.XWikiSkinsSheet` and users unable to upgrade are advised to manually patch their installations. | |||||
