#VU39351 Input validation error in Revive Adserver - CVE-2016-9471
Published: March 28, 2017 / Updated: August 8, 2020
Revive Adserver
OpenX Source
Description
The vulnerability allows a remote privileged user to read and manipulate data.
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. <a href="http://cwe.mitre.org/data/definitions/75.html">CWE-75: Failure to Sanitize Special Elements into a Different Plane (Special Element Injection)</a>
