Debian DLA-1215-1 : otrs2 security update

high Nessus Plugin ID 105396

Language:

Synopsis

The remote Debian host is missing a security update.

Description

Francesco Sirocco discovered a flaw in otrs2, the Open Ticket Request System, which could result in session information disclosure when cookie support is disabled. A remote attacker can take advantage of this flaw to take over an agent's session if the agent is tricked into clicking a link in a specially crafted mail.

For Debian 7 'Wheezy', these problems have been fixed in version 3.3.18-1~deb7u3.

We recommend that you upgrade your otrs2 packages.

NOTE: Tenable Network Security has extracted the preceding description block directly from the DLA security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

Solution

Upgrade the affected otrs, and otrs2 packages.
