CVE-2025-54834 2025-07-31 5.3 Medium
OPEXUS FOIAXpress Public Access Link (PAL) version v11.1.0 allows an unauthenticated, remote attacker to query the /App/CreateRequest.aspx endpoint to check for the existence of valid usernames. There are no rate-limiting mechanisms in place.
CVE-2022-20633 1 Cisco 1 Enterprise Chat And Email 2025-07-31 5.3 Medium
A vulnerability in the web-based management interface of Cisco ECE could allow an unauthenticated, remote attacker to perform a username enumeration attack against an affected device. This vulnerability is due to differences in authentication responses that are sent back from the application as part of an authentication attempt. An attacker could exploit this vulnerability by sending authentication requests to an affected device. A successful exploit could allow the attacker to confirm existing user accounts, which could be used in further attacks. Cisco has released software updates that address this vulnerability. There are no workarounds that address this vulnerability.
CVE-2025-54129 1 Haxtheweb 1 Hax 2025-07-23 4.3 Medium
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 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-2024-13028 1 Antabot 1 White-jotter 2025-07-12 3.7 Low
A vulnerability, which was classified as problematic, has been found in Antabot White-Jotter up to 0.2.2. This issue affects some unknown processing of the file /login. The manipulation of the argument username leads to observable response discrepancy. The attack may be initiated remotely. The complexity of an attack is rather high. The exploitation is known to be difficult. The exploit has been disclosed to the public and may be used.
CVE-2024-12663 1 Funnyzpc 1 Mee-admin 2025-07-12 3.7 Low
A vulnerability classified as problematic was found in funnyzpc Mee-Admin up to 1.6. This vulnerability affects unknown code of the file /mee/login of the component Login. The manipulation of the argument username leads to observable response discrepancy. The attack can be initiated remotely. The complexity of an attack is rather high. The exploitation appears to be difficult. The exploit has been disclosed to the public and may be used.
CVE-2025-1101 1 Q-free 1 Maxtime 2025-07-12 5.3 Medium
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-2025-24023 1 Dpgaspar 1 Flask-appbuilder 2025-07-12 3.7 Low
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-2025-30150 1 Shopware 1 Shopware 2025-07-12 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 1 Zitadel 1 Zitadel 2025-07-12 5.3 Medium
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-2025-27451 2025-07-03 5.3 Medium
For failed login attempts, the application returns different error messages depending on whether the login failed due to an incorrect password or a non-existing username. This allows an attacker to guess usernames until they find an existing one.
CVE-2025-3092 2025-06-26 7.5 High
An unauthenticated remote attacker can enumerate valid user names from an unprotected endpoint.
CVE-2024-28232 2 Icewhale, Icewhaletech 2 Casaos-userservice, Casaos-userservice 2025-06-24 6.2 Medium
Go package IceWhaleTech/CasaOS-UserService provides user management functionalities to CasaOS. The Casa OS Login page has disclosed the username enumeration vulnerability in the login page which was patched in version 0.4.7. This issue in CVE-2024-28232 has been patched in version 0.4.8 but that version has not yet been uploaded to Go's package manager.
CVE-2025-5485 2025-06-16 8.6 High
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-2025-49187 2025-06-12 5.3 Medium
For failed login attempts, the application returns different error messages depending on whether the login failed due to an incorrect password or a non-existing username. This allows an attacker to guess usernames until they find an existing one.
CVE-2025-30280 2025-06-10 5.3 Medium
A vulnerability has been identified in Mendix Runtime V10 (All versions < V10.21.0), Mendix Runtime V10.12 (All versions < V10.12.16), Mendix Runtime V10.18 (All versions < V10.18.5), Mendix Runtime V10.6 (All versions < V10.6.22), Mendix Runtime V8 (All versions < V8.18.35), Mendix Runtime V9 (All versions < V9.24.34). Affected applications allow for entity enumeration due to distinguishable responses in certain client actions. This could allow an unauthenticated remote attacker to list all valid entities and attribute names of a Mendix Runtime-based application.
