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-2024-1145 2024-11-21 N/A 5.3 MEDIUM
User enumeration vulnerability in Devklan's Alma Blog that affects versions 2.1.10 and earlier. This vulnerability could allow a remote user to retrieve all valid users registered in the application just by looking at the request response.
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-2023-39343 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-2023-33859 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-2022-41697 1 Ghost 1 Ghost 2024-11-21 N/A 5.3 MEDIUM
A user enumeration vulnerability exists in the login functionality of Ghost Foundation Ghost 5.9.4. A specially-crafted HTTP request can lead to a disclosure of sensitive information. An attacker can send a series of HTTP requests to trigger this vulnerability.
CVE-2022-31248 1 Suse 1 Manager Server 2024-11-21 5.0 MEDIUM 5.3 MEDIUM
A Observable Response Discrepancy vulnerability in spacewalk-java of SUSE Manager Server 4.1, SUSE Manager Server 4.2 allows remote attackers to discover valid usernames. This issue affects: SUSE Manager Server 4.1 spacewalk-java versions prior to 4.1.46-1. SUSE Manager Server 4.2 spacewalk-java versions prior to 4.2.37-1.

CVE-2022-20633 2024-11-18 N/A 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-2024-47129 1 Gotenna 1 Gotenna Pro 2024-10-17 N/A 4.3 MEDIUM
The goTenna Pro App does not inject extra characters into broadcasted frames to obfuscate the length of messages. This makes it possible to tell the length of the payload regardless of the encryption used.
