AI-suggested
Organizations should immediately verify their Revive Adserver versions and upgrade to patched releases once available. In the absence of official patches, administrators should implement strict access controls and monitor user account changes closely. Restricting login access to trusted personnel and enabling multi-factor authentication (MFA) can reduce the risk of attacker login. Additionally, auditing logs for unusual email change requests or password resets can help detect exploitation attempts early. Network segmentation of the ad server environment and limiting its access to essential personnel and systems will reduce the attack surface. If possible, temporarily disabling the forgot password functionality or adding additional verification steps for email changes can serve as interim mitigations. Finally, educating users about phishing and suspicious account activity can help prevent attackers from leveraging compromised credentials.
Description
Authorization bypass in Revive Adserver 5.5.2 and 6.0.1 and earlier versions causes an logged in attacker to change other users' email address and potentialy take over their accounts using the forgot password functionality.
