What it is
From the CVE record
A logic vulnerability in the password reset token validation routine implemented by osTicket in versions prior to v1.17.8 and v1.18.4. During the password reset process, the application retrieves the timestamp associated with the provided token and checks whether the configured validity period has expired. Consequently, the expiry check is only performed if the timestamp lookup fails, allowing tokens with an existing timestamp to bypass the intended expiry validation. Therefore, an attacker able to obtain a valid password reset token could reuse it to perform an unauthorised password reset and compromise the affected account.
