Cisco Secure Access Control Server (ACS) 3.2(3) and earlier spawns a separate unauthenticated TCP connection on a random port when a user authenticates to the ACS GUI, which allows remote attackers to bypass authentication by connecting to that port from the same IP address.

The CSAdmin web administration interface for Cisco Secure Access Control Server (ACS) 3.2(2) build 15 allows remote attackers to cause a denial of service (hang) via a flood of TCP connections to port 2002.

Cisco Secure Access Control Server (ACS) 3.2(3) and earlier, when configured with an anonymous bind in Novell Directory Services (NDS) and authenticating NDS users with NDS, allows remote attackers to gain unauthorized access to AAA clients via a blank password.

Buffer overflow in the administration service (CSAdmin) for Cisco Secure ACS before 3.1.2 allows remote attackers to cause a denial of service and possibly execute arbitrary code via a long user parameter to port 2002.

Format string vulnerability in the administration function in Cisco Secure Access Control Server (ACS) for Windows, 2.6.x and earlier and 3.x through 3.01 (build 40), allows remote attackers to crash the CSADMIN module only (denial of service of administration function) or execute arbitrary code via format strings in the URL to port 2002.

The administration function in Cisco Secure Access Control Server (ACS) for Windows, 2.6.x and earlier and 3.x through 3.01 (build 40), allows remote attackers to read HTML, Java class, and image files outside the web root via a ..\.. (modified ..) in the URL to port 2002.

Buffer overflow in CSAdmin module in CiscoSecure ACS Server 2.4(2) and earlier allows remote attackers to cause a denial of service and possibly execute arbitrary commands via a large packet.
