TITLE

Cisco Secure Access Control System Vulnerabilities that bypass authentication

Trust: 0.8

sources: JVNDB: JVNDB-2012-005294

DESCRIPTION

Cisco Secure Access Control System (ACS) 5.x before 5.2 Patch 11 and 5.3 before 5.3 Patch 7, when a certain configuration involving TACACS+ and LDAP is used, does not properly validate passwords, which allows remote attackers to bypass authentication by sending a valid username and a crafted password string, aka Bug ID CSCuc65634. This issue is being tracked by Cisco Bug ID CSCuc65634. The server provides a comprehensive identity-based access control solution for the Cisco Intelligent Information Network. When using certain configurations including TACACS+ and LDAP, passwords were not properly validated. ---------------------------------------------------------------------- The final version of the CSI 6.0 has been released.

The vulnerability is caused due to an error when validating a password when used via the TACACS+ authentication protocol and can be exploited to gain access without authentication. Successful exploitation requires that LDAP is configured as an external identity store and knowledge of a valid username. The vulnerability is reported in versions 5.0 through 5.3.
