Description:
Some security issues have been reported in Cisco Unified IP Conference Station and IP Phones, which can be exploited by malicious people to access a vulnerable device.

1) A design error in way the administrative HTTP interface of Cisco Unified IP Conference Station handles the state of administrator login sessions can be exploited to bypass the user authentication by accessing management URLs directly.

2) A hard-coded user account on various Cisco Unified IP Phones can be exploited to remotely access the CLI (Command Line Interface) of a vulnerable IP phone. This can further be exploited to cause a DoS (Denial of Service) or gain escalated privileges.

Solution:
Update to a fixed version (see the vendor's advisory for details).

Provided and/or discovered by:
1) The vendor credits Christian Reichert, Christian Blum, and Jens Link of Intact Integrated Services.
2) Reported by the vendor.

Changelog:
2007-03-02: Added CVE reference.
