CyberRota Analysis
AI-GeneratedThe vulnerability affects the account activation and password recovery mechanisms, allowing attackers to exploit stateless signed tokens that can be reused multiple times during their validity period. This weakness enables an attacker to gain unauthorized access to accounts by replaying captured activation or recovery links, even after the password has been changed. Organizations using this mechanism should prioritize patching to implement purpose-bound tokens and nonce validation to mitigate the risk of account takeover.

Original NVD Description
Vulnerability-Lookup contains an authentication weakness in its account activation and password-recovery mechanism. Activation and recovery links were generated using stateless signed tokens containing only the user's login. Although the token signature and age were validated, the application did not track whether a token had already been successfully used. As a result, a captured activation or password-recovery link remained valid for the entire configured TOKEN_VALIDITY_PERIOD, even after the associated password had been changed. An attacker who obtains a valid activation or recovery token could therefore replay it multiple times during its validity period to set a new password and repeatedly take control of the affected account. In addition, tokens were not bound to a specific purpose, allowing the same token mechanism to be used across activation and recovery workflows. The patch introduces purpose-bound tokens and a random nonce whose SHA-256 digest is stored with the user account. The nonce is invalidated after a successful password change, making tokens single-use, while issuing a new token invalidates any previously issued token. The password-setting operation now explicitly consumes the token before committing the account change. Successful exploitation requires the attacker to obtain a currently valid activation or recovery link, but does not require knowledge of the victim's existing password or an authenticated session.
