PT-2011-26: Multiple Cross-Site Request Forgery and "Stored XSS" Vulnerabilities in Cisco ACS
Version: 126.96.36.199 and earlier, 188.8.131.52 and earlier
Severity level: Medium
Impact: Cross-Site Request Forgery
Access Vector: Network exploitable
Base Score: 6.8
Cisco Secure Access Control Server (ACS) is an access policy control platform.
Positive Research Center has discovered multiple Cross-Site Request Forgery and "stored XSS" Vulnerabilities in Cisco ACS.
Forms do not provide protection against CSRF attacks. One can create a spoofing web form and trick the Cisco ACS administrator into submitting it. If the administrator already logged in to the Cisco ACS web interface, this may result in changing the ACS configuration. Moreover, requests of this type can be generated by spoofing a web page implicitly through a browser plug-in (e.g. Flash, Silverlight, or Java applet). In this case, the intruder has to trick the administrator into navigating through the spoofing page containing an exploit.
The details are not disclosed by agreement with the Cisco company.
