        AusCERT Advisory Summary
        ------------------------

Product:              Nortel Contact Center Manager
Operating System:     Windows
Impact:               Inappropriate Access

OVERVIEW:

      Nortel has released two security bulletins identifying vulnerabilities
      in the Nortel Contact Center Manager.


IMPACT:

      "The Nortel Contact Center Manager Administration Server web 
      application relies on client side cookies to check the roles of 
      authenticated users. Authentication can be bypassed by manually 
      setting the required cookies. By exploiting this vulnerability, an 
      attacker can bypass authentication and access the Nortel Contact 
      Center Manager Administration web administration." [1]

      "The Nortel Contact Center Manager Server web application provides a 
      SOAP interface. This interface does not need authorisation and 
      responds to certain requests with sensitive information." [2]


MITIGATION:

      Please refer to the Nortel advisories [1, 2] for fixes to your specific 
      product.
