CVE-2024-40627 2024-11-21 N/A 5.8 MEDIUM
Fastapi OPA is an opensource fastapi middleware which includes auth flow. HTTP `OPTIONS` requests are always allowed by `OpaMiddleware`, even when they lack authentication, and are passed through directly to the application. `OpaMiddleware` allows all HTTP `OPTIONS` requests without evaluating it against any policy. If an application provides different responses to HTTP `OPTIONS` requests based on an entity existing (such as to indicate whether an entity is writable on a system level), an unauthenticated attacker could discover which entities exist within an application. This issue has been addressed in release version 2.0.1. All users are advised to upgrade. There are no known workarounds for this vulnerability.
CVE-2024-39912 2024-11-21 N/A 5.3 MEDIUM
web-auth/webauthn-lib is an open source set of PHP libraries and a Symfony bundle to allow developers to integrate that authentication mechanism into their web applications. The ProfileBasedRequestOptionsBuilder method returns allowedCredentials without any credentials if no username was found. When WebAuthn is used as the first or only authentication method, an attacker can enumerate usernames based on the absence of the `allowedCredentials` property in the assertion options response. This allows enumeration of valid or invalid usernames. By knowing which usernames are valid, attackers can focus their efforts on a smaller set of potential targets, increasing the efficiency and likelihood of successful attacks. This issue has been addressed in version 4.9.0 and all users are advised to upgrade. There are no known workarounds for this vulnerability.
CVE-2024-39211 2024-11-21 N/A 5.3 MEDIUM
Kaiten 57.128.8 allows remote attackers to enumerate user accounts via a crafted POST request, because a login response contains a user_email field only if the user account exists.
CVE-2024-38431 1 Matrix-globalservices 1 Tafnit 2024-11-21 N/A 5.3 MEDIUM
Matrix Tafnit v8 - CWE-204: Observable Response Discrepancy
CVE-2024-38322 1 Ibm 1 Storage Defender Resiliency Service 2024-11-21 N/A 5.3 MEDIUM
IBM Storage Defender - Resiliency Service 2.0.0 through 2.0.4 agent username and password error response discrepancy exposes product to brute force enumeration. IBM X-Force ID: 294869.
CVE-2024-36996 1 Splunk 2 Splunk, Splunk Cloud Platform 2024-11-21 N/A 5.3 MEDIUM
In Splunk Enterprise versions below 9.2.2, 9.1.5, and 9.0.10 and Splunk Cloud Platform versions below 9.1.2312.109, an attacker could determine whether or not another user exists on the instance by deciphering the error response that they would likely receive from the instance when they attempt to log in. This disclosure could then lead to additional brute-force password-guessing attacks. This vulnerability would require that the Splunk platform instance uses the Security Assertion Markup Language (SAML) authentication scheme.
CVE-2024-31870 1 Ibm 1 I 2024-11-21 N/A 3.3 LOW
IBM Db2 for i 7.2, 7.3, 7.4, and 7.5 supplies user defined table function is vulnerable to user enumeration by a local authenticated attacker, without having authority to the related *USRPRF objects. This can be used by a malicious actor to gather information about users that can be targeted in further attacks. IBM X-Force ID: 287174.
CVE-2023-4095 1 Fujitsu 1 Arconte Aurea 2024-11-21 N/A 5.3 MEDIUM
User enumeration vulnerability in Arconte Áurea 1.5.0.0 version. The exploitation of this vulnerability could allow an attacker to obtain a list of registered users in the application, obtaining the necessary information to perform more complex attacks on the platform.
CVE-2023-41885 1 Piccolo-orm 1 Piccolo 2024-11-21 N/A 5.3 MEDIUM
Piccolo is an ORM and query builder which supports asyncio. In versions 0.120.0 and prior, the implementation of `BaseUser.login` leaks enough information to a malicious user such that they would be able to successfully generate a list of valid users on the platform. As Piccolo on its own does not also enforce strong passwords, these lists of valid accounts are likely to be used in a password spray attack with the outcome being attempted takeover of user accounts on the platform. The impact of this vulnerability is minor as it requires chaining with other attack vectors in order to gain more then simply a list of valid users on the underlying platform. The likelihood of this vulnerability is possible as it requires minimal skills to pull off, especially given the underlying login functionality for Piccolo based sites is open source. This issue has been patched in version 0.121.0.
CVE-2023-40179 1 Silverwaregames 1 Silverwaregames 2024-11-21 N/A 5.3 MEDIUM
Silverware Games is a premium social network where people can play games online. Prior to version 1.3.6, the Password Recovery form would throw an error if the specified email was not found in our database. It would only display the "Enter the code" form if the email is associated with a member of the site. Since version 1.3.6, the "Enter the code" form is always returned, showing the message "If the entered email is associated with an account, a code will be sent now". This change prevents potential violators from determining if our site has a user with the specified email.
CVE-2023-3336 1 Moxa 2 Tn-5900, Tn-5900 Firmware 2024-11-21 N/A 5.3 MEDIUM
TN-5900 Series version 3.3 and prior versions is vulnearble to user enumeration vulnerability. The vulnerability may allow a remote attacker to determine whether a user is valid during password recovery through the web login page and enable a brute force attack with valid users.
CVE-2023-3221 1 Password Recovery Project 1 Password Recovery 2024-11-21 N/A 5.3 MEDIUM
User enumeration vulnerability in Password Recovery plugin 1.2 version for Roundcube, which could allow a remote attacker to create a test script against the password recovery function to enumerate all users in the database.
CVE-2023-39343 1 Sulu 1 Sulu 2024-11-21 N/A 4.3 MEDIUM
Sulu is an open-source PHP content management system based on the Symfony framework. It allows over the Admin Login form to detect which user (username, email) exists and which one do not exist. Sulu Installation not using the old Symfony 5.4 security System and previous version are not impacted by this Security issue. The vulnerability has been patched in version 2.5.10.
CVE-2023-37831 1 Elenos 2 Etg150, Etg150 Firmware 2024-11-21 N/A 5.3 MEDIUM
An issue discovered in Elenos ETG150 FM transmitter v3.12 allows attackers to enumerate user accounts based on server responses when credentials are submitted.
CVE-2023-37217 1 Tadirantele 1 Aeonix 2024-11-21 N/A 5.3 MEDIUM
Tadiran Telecom Aeonix - CWE-204: Observable Response Discrepancy
CVE-2023-35698 1 Sick 2 Icr890-4, Icr890-4 Firmware 2024-11-21 N/A 5.3 MEDIUM
Observable Response Discrepancy in the SICK ICR890-4 could allow a remote attacker to identify valid usernames for the FTP server from the response given during a failed login attempt.
CVE-2023-33859 1 Ibm 1 Security Qradar Edr 2024-11-21 N/A 5.3 MEDIUM
IBM Security QRadar EDR 3.12 could disclose sensitive information due to an observable login response discrepancy. IBM X-Force ID: 257697.
CVE-2023-32346 1 Teltonika 1 Remote Management System 2024-11-21 N/A 5.3 MEDIUM
Teltonika’s Remote Management System versions prior to 4.10.0 contain a function that allows users to claim their devices. This function returns information based on whether the serial number of a device has already been claimed, the MAC address of a device has already been claimed, or whether the attempt to claim a device was successful. An attacker could exploit this to create a list of the serial numbers and MAC addresses of all devices cloud-connected to the Remote Management System.
CVE-2023-31186 1 Avaya 1 Ix Workforce Engagement 2024-11-21 N/A 5.3 MEDIUM
Avaya IX Workforce Engagement v15.2.7.1195 - User Enumeration - Observable Response Discrepancy
