Thorsten Eckel of Znuny GMBH and Remo Staeuble of InfoGuard discovered a privilege escalation vulnerability in otrs2, the Open Ticket Request System. An attacker with valid OTRS credentials could access and manipulate ticket data of other users via the GenericInterface, if a ticket webservice is configured and not additionally secured.

For the stable distribution (wheezy), this problem has been fixed in version 3.1.7+dfsg1-8+deb7u5. For the upcoming stable distribution (jessie), this problem has been fixed in version 3.3.9-3. For the unstable distribution (sid), this problem has been fixed in version 3.3.9-3. We recommend that you upgrade your otrs2 packages.

OTRS is an Open source Ticket Request System (also well known as trouble ticket system) with many features to manage customer telephone calls and e-mails. The system is built to allow your support, sales, pre-sales, billing, internal IT, helpdesk, etc. department to react quickly to inbound inquiries. For a detailed documentation see package otrs-doc-en or otrs-doc-de.
