Detailsinfo

A vulnerability was found in MantisBT up to 2.26.1 and classified as critical. This issue affects some unknown functionality of the file account_update.php of the component Password Reset Handler. The manipulation with an unknown input leads to a authentication bypass vulnerability. Using CWE to declare the problem leads to CWE-305. The authentication algorithm is sound, but the implemented mechanism can be bypassed as the result of a separate weakness that is primary to the authentication error. Impacted is confidentiality, integrity, and availability. The summary by CVE is:

MantisBT (Mantis Bug Tracker) is an open source issue tracker. Insufficient access control in the registration and password reset process allows an attacker to reset another user's password and takeover their account, if the victim has an incomplete request pending. The exploit is only possible while the verification token is valid, i.e for 5 minutes after the confirmation URL sent by e-mail has been opened, and the user did not complete the process by updating their password. A brute-force attack calling account_update.php with increasing user IDs is possible. A successful takeover would grant the attacker full access to the compromised account, including sensitive information and functionalities associated with the account, the extent of which depends on its privileges and the data it has access to. Version 2.26.2 contains a patch for the issue. As a workaround, one may mitigate the risk by reducing the verification token's validity (change the value of the `TOKEN_EXPIRY_AUTHENTICATED` constant in `constants_inc.php`).

The advisory is shared at github.com. The identification of this vulnerability is CVE-2024-34077 since 04/30/2024. The exploitation is known to be easy. The attack may be initiated remotely. No form of authentication is needed for a successful exploitation. Technical details are known, but no exploit is available.
