Package : otrs2
CVE ID : CVE-2017-17476
Debian Bug : 884801

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 the oldstable distribution (jessie), this problem has been fixed
in version 3.3.18-1+deb8u4.

For the stable distribution (stretch), this problem has been fixed in
version 5.0.16-1+deb9u5.

We recommend that you upgrade your otrs2 packages.
