The manipulation as part of a Control Character leads to a unknown weakness. The CWE definition for the vulnerability is CWE-75. As an impact it is known to affect confidentiality, and integrity. The summary by CVE is:

Revive Adserver before 3.2.5 and 4.0.0 suffers from Special Element Injection. Usernames weren't properly sanitised when creating users on a Revive Adserver instance. Especially, control characters were not filtered, allowing apparently identical usernames to co-exist in the system, due to the fact that such characters are normally ignored when an HTML page is displayed in a browser. The issue could have therefore been exploited for user spoofing, although elevated privileges are required to create users within Revive Adserver.

The attack can be launched remotely. The exploitation doesn't need any form of authentication. It demands that the victim is doing some kind of user interaction. The technical details are unknown and an exploit is not publicly available.

The vulnerability was handled as a non-public zero-day exploit for at least 180 days. During that time the estimated underground price was around $0-$5k.

Upgrading to version 3.2.5 eliminates this vulnerability.
