To any system using TACACS+ in combination with an affected Cisco Secure An exploit could allow the attacker to successfully authenticate Vulnerability, and the exploitation is limited to impersonate only that user. The attacker would need to know a valid username stored in the LDAP external Secure ACS is configured with a Lightweight Directory Access ProtocolĪn attacker could exploit this vulnerability by sending a special sequenceĬharacters when prompted for the user password.
#CISCO SECURE ACCESS CONTROL SYSTEM 5.2 PASSWORD#
The vulnerability is due to improper validation of the user-supplied password when TACACS+ is as authentication protocol and Cisco Unauthenticated, remote attacker to bypass the TACACS+ based authentication In an external identity store, Cisco Secure ACS will retrieve information from an external database. An internal identity store has user credentials information stored in an internal database. The identity stores can be internal or external.
#CISCO SECURE ACCESS CONTROL SYSTEM 5.2 PATCH#
The example above shows a Cisco Secure ACS running version 5.1 Patch 6.Ĭisco Secure Access Control System (ACS) operates as a centralized RADIUS and TACACS+ server,Ĭombining user authentication, user and administrator device access control,Īnd policy control into a centralized identity networking solution.Ĭisco Secure ACS provides authentication, authorization, and accounting (AAA) services to network devices and other clients by using the Cisco Secure ACS network resource repositories and identity stores. The absence of any additionalĭigit after the version string indicates a Cisco Secure ACS version with no ForĮxample, a version number of 5.1.0.44.3 indicates Cisco SecureĪCS version 5.1 with up to patch 3 installed.
