Description:
Some vulnerabilities have been reported in Cisco Secure ACS, which can be exploited by malicious users or people to cause a DoS (Denial of Service) or to compromise a vulnerable system.
1) An unspecified error within the CSAdmin service when processing HTTP GET requests can be exploited to cause a stack-based buffer overflow via a specially crafted HTTP GET request.
Successful exploitation allows execution of arbitrary code.
2) An unspecified error within the CSRadius service when processing RADIUS Accounting-Request packets can be exploited to cause a stack-based buffer overflow via a specially crafted RADIUS Accounting-Request packet.
Successful exploitation allows execution of arbitrary code.
3) Unspecified errors within the CSRadius service when processing RADIUS Access-Request packets can be exploited to crash the service via a specially crafted RADIUS Access-Request packet.
The vulnerabilities are reported in versions prior to 4.1. Other versions may also be affected.
Note: The following products are reportedly not affected:
* Cisco Secure ACS for Unix (CSU).
* Cisco CNS Access Registrar (CAR).
