Revive Adserver before 3.2.3 suffers from Information Exposure Through Discrepancy. It is possible to check whether or not an email address was associated to one or more user accounts on a target Revive Adserver instance by examining the message printed by the password recovery system. Such information cannot however be used directly to log in to the system, which requires a username.

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 Cross-Site Request Forgery (CSRF). The Revive Adserver team conducted a security audit of the admin interface scripts in order to identify and fix other potential CSRF vulnerabilities. Over 20+ such issues were fixed.

Revive Adserver before 3.2.5 and 4.0.0 suffers from Reflected File Download. `www/delivery/asyncspc.php` was vulnerable to the fairly new Reflected File Download (RFD) web attack vector that enables attackers to gain complete control over a victim's machine by virtually downloading a file from a trusted domain.

Revive Adserver before 3.2.3 suffers from Persistent XSS. A vector for persistent XSS attacks via the Revive Adserver user interface exists, requiring a trusted (non-admin) account. The banner image URL for external banners wasn't properly escaped when displayed in most of the banner related pages.

Revive Adserver before 3.2.3 suffers from persistent XSS. Usernames are not properly escaped when displayed in the audit trail widget of the dashboard upon login, allowing persistent XSS attacks. An authenticated user with enough privileges to create other users could exploit the vulnerability to access the administrator account.

Revive Adserver before 3.2.3 suffers from Cross-Site Request Forgery (CSRF). A number of scripts in Revive Adserver's user interface are vulnerable to CSRF attacks: `www/admin/banner-acl.php`, `www/admin/banner-activate.php`, `www/admin/banner-advanced.php`, `www/admin/banner-modify.php`, `www/admin/banner-swf.php`, `www/admin/banner-zone.php`, `www/admin/tracker-modify.php`.

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.

Cross-site scripting (XSS) vulnerability in Revive Adserver before 4.0.1 allows remote authenticated users to inject arbitrary web script or HTML via the user's email address.

Revive Adserver before 4.0.1 allows remote attackers to execute arbitrary code via serialized data in the cookies related to the delivery scripts.
