Description Kurt Seifried 2012-08-28 02:14:42 UTC
Russel Bryant (rbryant@redhat.com) from the OpenStack Project reports:

Title: Open redirect through 'next' parameter
Impact: Medium
Reporter: Thomas Biege (SUSE)
Products: Horizon
Affects: Essex

Thomas Biege from SUSE reported a vulnerability in Horizon
authentication mechanism. By adding a malicious 'next' parameter to a
Horizon authentication URL and enticing an unsuspecting user to follow
it, the victim might get redirected after authentication to a
malicious site where useful information could be extracted. Only
setups running Essex are affected.

Proposed patch:
See attached diff. This proposed patch will be merged into the
stable/essex branch on the public disclosure date.
