CVE-2016-9124: Revive Adserver login permits password-guessing attacks
CVE-2016-9124 · published 9 years ago
Summary
The login screen of Revive Adserver versions before 3.2.3 does not stop repeated password attempts, so an attacker could keep trying guesses until a correct one is found. Because there is no automatic lockout, the system relies only on small delays, which may not be enough to stop a determined attacker. Upgrade to Revive Adserver 3.2.3 or later and enforce strong, unique passwords for all accounts; consider adding extra login protections such as multi‑factor authentication or rate‑limiting.

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.
