| CVE-2021-29433 | 1 Matrix | 1 Sydent | 2022-08-02 | 4.0 MEDIUM | 4.3 MEDIUM |
| Sydent is a reference Matrix identity server. In Sydent versions 2.2.0 and prior, sissing input validation of some parameters on the endpoints used to confirm third-party identifiers could cause excessive use of disk space and memory leading to resource exhaustion. A patch for the vulnerability is in version 2.3.0. No workarounds are known to exist. | |||||
| CVE-2022-29166 | 1 Matrix | 1 Matrix Irc Bridge | 2022-05-16 | 6.8 MEDIUM | 8.8 HIGH |
| matrix-appservice-irc is a Node.js IRC bridge for Matrix. The vulnerability in node-irc allows an attacker to manipulate a Matrix user into executing IRC commands by having them reply to a maliciously crafted message. The vulnerability has been patched in matrix-appservice-irc 0.33.2. Refrain from replying to messages from untrusted participants in IRC-bridged Matrix rooms. There are no known workarounds for this issue. | |||||
| CVE-2021-32659 | 1 Matrix | 1 Matrix-appservice-bridge | 2021-07-09 | 3.5 LOW | 4.9 MEDIUM |
| Matrix-appservice-bridge is the bridging service for the Matrix communication program's application services. In versions 2.6.0 and earlier, if a bridge has room upgrade handling turned on in the configuration (the `roomUpgradeOpts` key when instantiating a new `Bridge` instance.), any `m.room.tombstone` event it encounters will be used to unbridge the current room and bridge into the target room. However, the target room `m.room.create` event is not checked to verify if the `predecessor` field contains the previous room. This means that any malicious admin of a bridged room can repoint the traffic to a different room without the new room being aware. Versions 2.6.1 and greater are patched. As a workaround, disabling the automatic room upgrade handling can be done by removing the `roomUpgradeOpts` key from the `Bridge` class options. | |||||
| CVE-2021-34813 | 1 Matrix | 1 Olm | 2021-06-23 | 7.5 HIGH | 9.8 CRITICAL |
| Matrix libolm before 3.2.3 allows a malicious Matrix homeserver to crash a client (while it is attempting to retrieve an Olm encrypted room key backup from the homeserver) because olm_pk_decrypt has a stack-based buffer overflow. Remote code execution might be possible for some nonstandard build configurations. | |||||
| CVE-2021-29431 | 1 Matrix | 1 Sydent | 2021-04-22 | 4.0 MEDIUM | 6.5 MEDIUM |
| Sydent is a reference Matrix identity server. Sydent can be induced to send HTTP GET requests to internal systems, due to lack of parameter validation or IP address blacklisting. It is not possible to exfiltrate data or control request headers, but it might be possible to use the attack to perform an internal port enumeration. This issue has been addressed in in 9e57334, 8936925, 3d531ed, 0f00412. A potential workaround would be to use a firewall to ensure that Sydent cannot reach internal HTTP resources. | |||||
| CVE-2020-26891 | 1 Matrix | 1 Synapse | 2020-10-26 | 4.3 MEDIUM | 6.1 MEDIUM |
| AuthRestServlet in Matrix Synapse before 1.21.0 is vulnerable to XSS due to unsafe interpolation of the session GET parameter. This allows a remote attacker to execute an XSS attack on the domain Synapse is hosted on, by supplying the victim user with a malicious URL to the /_matrix/client/r0/auth/*/fallback/web or /_matrix/client/unstable/auth/*/fallback/web Synapse endpoints. | |||||
| CVE-2019-18835 | 1 Matrix | 1 Synapse | 2020-08-24 | 7.5 HIGH | 9.8 CRITICAL |
| Matrix Synapse before 1.5.0 mishandles signature checking on some federation APIs. Events sent over /send_join, /send_leave, and /invite may not be correctly signed, or may not come from the expected servers. | |||||
| CVE-2018-12423 | 1 Matrix | 1 Synapse | 2019-10-03 | 5.0 MEDIUM | 7.5 HIGH |
| In Synapse before 0.31.2, unauthorised users can hijack rooms when there is no m.room.power_levels event in force. | |||||
| CVE-2018-12291 | 1 Matrix | 1 Synapse | 2019-10-03 | 5.0 MEDIUM | 7.5 HIGH |
| The on_get_missing_events function in handlers/federation.py in Matrix Synapse before 0.31.1 has a security bug in the get_missing_events federation API where event visibility rules were not applied correctly. | |||||
| CVE-2019-11842 | 1 Matrix | 2 Sydent, Synapse | 2019-05-10 | 5.0 MEDIUM | 7.5 HIGH |
| An issue was discovered in Matrix Sydent before 1.0.3 and Synapse before 0.99.3.1. Random number generation is mishandled, which makes it easier for attackers to predict a Sydent authentication token or a Synapse random ID. | |||||
| CVE-2019-11340 | 1 Matrix | 1 Sydent | 2019-04-22 | 4.3 MEDIUM | 5.9 MEDIUM |
| util/emailutils.py in Matrix Sydent before 1.0.2 mishandles registration restrictions that are based on e-mail domain, if the allowed_local_3pids option is enabled. This occurs because of potentially unwanted behavior in Python, in which an email.utils.parseaddr call on user@bad.example.net@good.example.com returns the user@bad.example.net substring. | |||||
| CVE-2018-10657 | 1 Matrix | 1 Synapse | 2018-06-07 | 5.0 MEDIUM | 7.5 HIGH |
| Matrix Synapse before 0.28.1 is prone to a denial of service flaw where malicious events injected with depth = 2^63 - 1 render rooms unusable, related to federation/federation_base.py and handlers/message.py, as exploited in the wild in April 2018. | |||||
| CVE-2004-2089 | 1 Matrix | 1 Matrix Ftp Server | 2017-07-11 | 5.0 MEDIUM | N/A |
| Matrix FTP Server allows remote attackers to cause a denial of service (crash) by logging in using four spaces as the username and password and then issuing a LIST command. | |||||
