Use of cryptographically weak PRNG in the password recovery token generation of Revive Adserver < v4.2.1 causes a potential authentication bypass attack if an attacker exploits the password recovery functionality. In lib/OA/Dal/PasswordRecovery.php, the function generateRecoveryId() generates a password reset token that relies on the PHP uniqid function and consequently depends only on the current server time, which is often visible in an HTTP Date header.

Revive Adserver before 3.2.3 suffers from Cross-Site Request Forgery (CSRF). The password recovery form in Revive Adserver is vulnerable to CSRF attacks. This vulnerability could be exploited to send a large number of password recovery emails to the registered users, especially in conjunction with a bug that caused recovery emails to be sent to all the users at once. Both issues have been fixed.

Revive Adserver before 3.2.3 suffers from session fixation, by allowing arbitrary session identifiers to be forced and, at the same time, by not invalidating the existing session upon a successful authentication. Under some circumstances, that could have been an opportunity for an attacker to steal an authenticated session.

Revive Adserver before 3.2.3 suffers from Improper Restriction of Excessive Authentication Attempts. The login page of Revive Adserver is vulnerable to password-guessing attacks. An account lockdown feature was considered, but rejected to avoid introducing service disruptions to regular users during such attacks. A random delay has instead been introduced as a countermeasure in case of password failures, along with a system to discourage parallel brute forcing. These systems will effectively allow the valid users to log in to the adserver, even while an attack is in progress.
