Description Jan Lieskovsky 2010-08-03 11:51:31 UTC

Sébastien PORTEFAIX reported:
  [1] https://issues.jasig.org/browse/PHPCAS-61

a deficiency in the way Central Authentication Service (CAS) client library
processed service tickets (the submitted service ticket was used to rename
the http session before it was validated). A remote attacker, intercepting
the communication, could use this flaw to hijack any authenticated user session.
