DESCRIPTION:
Some vulnerabilities have been reported in phpCAS, which can be
exploited by malicious people to conduct cross-site scripting attacks
and malicious users to hijack another user's session.

1) A vulnerability is caused due to phpCAS not properly validating
service tickets before assigning the new session. This can be
exploited to hijack another user's session by e.g. guessing valid
service tickets.

Successful exploitation requires valid user credentials.

2) The application does not properly sanitise the callback URL, which
can be exploited to execute arbitrary HTML and script code in a user's
browser session in context of an affected site.

Successful exploitation requires that the CAS proxy mode is used.

The vulnerabilities are reported in versions prior to 1.1.2.

SOLUTION:
Update to version 1.1.2.

PROVIDED AND/OR DISCOVERED BY:
1) Sébastien Portefaix
2) Reported by the vendor.
