Description Jan Lieskovsky 2010-08-03 12:07:56 UTC
Joachim Fritschi (upstream phpCAS developer) noticed:
  [1] https://issues.jasig.org/browse/PHPCAS-67

the Central Authentication Service (CAS) client library improperly
encoded the callback URLs (generated to validate service tickets) 
provided to CAS proxies. A remote attacker could use this flaw
to conduct cross-site scripting (XSS) attacks by providing a specially-crafted
value for service ticket.
