CWE-204: Observable Response Discrepancy
CVE-2025-52899 2025-07-29 N/A N/A
Tuleap is an Open Source Suite created to facilitate management of software development and collaboration. In Tuleap Community Edition prior to version 16.9.99.1750843170 and Tuleap Enterprise Edition prior to 16.8-4 and 16.9-2, the forgot password form allows for user enumeration. This is fixed in Tuleap Community Edition version 16.9.99.1750843170 and Tuleap Enterprise Edition 16.8-4 and 16.9-2.
CVE-2025-54129 2025-07-21 N/A N/A
HAXiam is a packaging wrapper for HAXcms which allows anyone to spawn their own microsite management platform. In versions 11.0.4 and below, the application returns a 200 response when requesting the data of a valid user and a 404 response when requesting the data of an invalid user. This can be used to infer the existence of valid user accounts. An authenticated attacker can use automated tooling to brute force potential usernames and use the application's response to identify valid accounts. This can be used in conjunction with other vulnerabilities, such as the lack of authorization checks, to enumerate and deface another user's sites. This is fixed in version 11.0.5.
CVE-2024-56476 2 Ibm, Linux 3 Aix, Txseries For Multiplatforms, Linux Kernel 2025-07-15 N/A 5.3 MEDIUM
IBM TXSeries for Multiplatforms 9.1 and 11.1 could allow an attacker to enumerate usernames due to an observable login attempt response discrepancy.
CVE-2025-3092 2025-06-24 N/A 7.5 HIGH
An unauthenticated remote attacker can enumerate valid user names from an unprotected endpoint.
CVE-2025-5485 2025-06-16 N/A N/A
User names used to access the web management interface are limited to the device identifier, which is a numerical identifier no more than 10 digits. A malicious actor can enumerate potential targets by incrementing or decrementing from known identifiers or through enumerating random digit sequences.
CVE-2024-51447 2025-05-13 N/A 5.3 MEDIUM
A vulnerability has been identified in Polarion V2310 (All versions), Polarion V2404 (All versions < V2404.2). The login implementation of the affected application contains an observable response discrepancy vulnerability when validating usernames. This could allow an unauthenticated remote attacker to distinguish between valid and invalid usernames.
CVE-2025-46736 2025-05-06 N/A N/A
Umbraco is a free and open source .NET content management system. Prior to versions 10.8.10 and 13.8.1, based on an analysis of the timing of post login API responses, it's possible to determine whether an account exists. The issue is patched in versions 10.8.10 and 13.8.1. No known workarounds are available.
CVE-2025-30150 2025-04-08 N/A N/A
Shopware 6 is an open commerce platform based on Symfony Framework and Vue. Through the store-api it is possible as a attacker to check if a specific e-mail address has an account in the shop. Using the store-api endpoint /store-api/account/recovery-password you get the response, which indicates clearly that there is no account for this customer. In contrast you get a success response if the account was found. This vulnerability is fixed in Shopware 6.6.10.3 or 6.5.8.17. For older versions of 6.4, corresponding security measures are also available via a plugin. For the full range of functions, we recommend updating to the latest Shopware version.
CVE-2025-31124 2025-04-01 N/A N/A
Zitadel is open-source identity infrastructure software. ZITADEL administrators can enable a setting called "Ignoring unknown usernames" which helps mitigate attacks that try to guess/enumerate usernames. If enabled, ZITADEL will show the password prompt even if the user doesn't exist and report "Username or Password invalid". While the setting was correctly respected during the login flow, the user's username was normalized leading to a disclosure of the user's existence. This vulnerability is fixed in 2.71.6, 2.70.8, 2.69.9, 2.68.9, 2.67.13, 2.66.16, 2.65.7, 2.64.6, and 2.63.9.
CVE-2025-2910 2025-03-28 N/A N/A
User enumeration in the password reset module of the MeetMe authentication service in versions prior to 2024-09 allows an attacker to determine whether an email address is registered through specific error messages.
CVE-2025-24023 1 Dpgaspar 1 Flask-appbuilder 2025-03-07 N/A 5.3 MEDIUM
Flask-AppBuilder is an application development framework. Prior to 4.5.3, Flask-AppBuilder allows unauthenticated users to enumerate existing usernames by timing the response time from the server when brute forcing requests to login. This vulnerability is fixed in 4.5.3.
CVE-2023-47159 1 Ibm 1 Sterling File Gateway 2025-03-05 N/A 4.3 MEDIUM
IBM Sterling File Gateway 6.0.0.0 through 6.1.2.5 and 6.2.0.0 through 6.2.0.1 could allow an authenticated user to enumerate usernames due to an observable discrepancy in request responses.
CVE-2023-37413 1 Ibm 1 Aspera Faspex 2025-03-04 N/A 5.3 MEDIUM
IBM Aspera Faspex 5.0.0 through 5.0.10 could disclose sensitive username information due to an observable response discrepancy.
CVE-2024-35114 1 Ibm 1 Control Center 2025-03-04 N/A 5.3 MEDIUM
IBM Control Center 6.2.1 and 6.3.1 could allow a remote attacker to enumerate usernames due to an observable discrepancy between login attempts.
CVE-2025-1101 2025-02-12 N/A N/A
A CWE-204 "Observable Response Discrepancy" in the login page in Q-Free MaxTime less than or equal to version 2.11.0 allows an unauthenticated remote attacker to enumerate valid usernames via crafted HTTP requests.
CVE-2025-23193 2025-02-11 N/A 5.3 MEDIUM
SAP NetWeaver Server ABAP allows an unauthenticated attacker to exploit a vulnerability that causes the server to respond differently based on the existence of a specified user, potentially revealing sensitive information. This issue does not enable data modification and has no impact on server availability.
CVE-2025-23214 2025-01-20 N/A N/A
Cosmos provides users the ability self-host a home server by acting as a secure gateway to your application, as well as a server manager. By monitoring the error code returned in the login, it is possible to figure out whether a user exist or not in the database. Patched in 0.17.7.
