Date Reported:
16 Jan 2017
Affected Packages:
Security database references:
In the Debian bugtracking system: Bug 843091.
In Mitre's CVE dictionary: CVE-2016-9139.
More information:

A cross-site sripting vulnerability (XSS) was discovered in OTRS, a ticket requesting system for the web. An attacker could trick an authenticated user into opening a malicious attachment which could lead to the execution of JavaScript in OTRS context. This update addresses the vulnerability by setting a strict default HTTP content security policy that forbids loading of third-party files.

For Debian 7 Wheezy, these problems have been fixed in version 3.1.7+dfsg1-8+deb7u6.

We recommend that you upgrade your otrs2 packages.
