Cisco Secure Access Control System (ACS) prior to version 5.5 patch 8 is vulnerable to a SQL injection attack in the ACS View reporting interface pages. A successful attack could allow an authenticated, remote attacker to access and modify information such as RADIUS accounting records stored in one of the ACS View databases or to access information in the underlying file system. A previous version of this advisory indicated that a product running version 5.5 patch 7 was not vulnerable; however, customers running version 5.5 patch 7 should upgrade to patch 8 to completely mitigate the vulnerability described in this advisory.
Cisco has released software updates that address this vulnerability.

Vulnerable Products
All versions of Cisco Secure ACS prior to version 5.5 patch 8 are affected by the SQL injection vulnerability in this advisory.
Products Confirmed Not Vulnerable
Cisco Secure ACS versions 5.6 and later are not affected by this vulnerability.
The following Cisco Secure ACS products are not affected by this vulnerability:
- Cisco Secure Access Control Server for Windows
- Cisco Secure Access Control Server Express
- Cisco Secure Access Control Server View
- Cisco Secure Access Control Server Solution Engine
-
A core component of the Cisco TrustSec solution, Cisco Secure ACS is a highly sophisticated policy platform providing RADIUS and TACACS+ services. It supports the increasingly complex policies needed to meet today's new demands for access control management and compliance. Cisco Secure ACS provides central management of access policies for device administration and wireless, wired 802.1x, and remote VPN network access scenarios. The identity stores can be internal or external. An internal identity store has user credential information stored in an internal database. With an external identity store, Cisco Secure ACS will retrieve information from an external database.
A vulnerability in the web framework code of Cisco ACS could allow an authenticated, remote attacker to execute arbitrary SQL queries on one of the two ACS View databases. The authentication requires access to an ACS administrator account.
The vulnerability is due to a failure to properly sanitize user-supplied input passed to the reporting application. An attacker could exploit this vulnerability by sending crafted requests to the web server using the HTTPS protocol.
This vulnerability has been documented in Cisco bug ID CSCuq79027 (registered customers only) and has been assigned the Common Vulnerabilities and Exposures (CVE) ID CVE-2015-0580.
