 There was a Cisco Product Security Incident Response Team (PSIRT)
advisory recently concerning some XSS/CSRF holes in the IOS..


Document ID: 98605
Revision 1.0
For Public Release 2009 January 14 1600 UTC (GMT)
Cisco Response:
"Two separate Cisco IOS® Hypertext Transfer Protocol (HTTP) cross-site
scripting (XSS) vulnerabilities have been reported to Cisco [...]
This response covers two separate cross-site scripting vulnerabilities
within the Cisco IOS Hypertext Transfer Protocol (HTTP) server
(including HTTP secure server - here after referred to as purely HTTP
Server) and applies to all Cisco products that run Cisco IOS Software
versions 11.0 through 12.4 with the HTTP server enabled.


According to this advisory these holes were patched in 12.4(15)T8 and

However i found that the Cisco IOS ( 12.4(23) ) HTTP Server is still
prone to multiple cross-site scripting vulnerabilities because it fails
to sufficiently sanitize user-supplied data.
The attacker may leverage these issues to execute arbitrary script code
in the browser of an unsuspecting user in the context of the affected site.

Proof of concept:

furchtbar#sh ver | i IOS
Cisco IOS Software, C2600 Software (C2600-ADVSECURITYK9-M), Version
12.4(23), RELEASE SOFTWARE (fc1)
furchtbar#show ip http server status | include status
HTTP server status: Enabled
HTTP secure server status: Enabled
furchtbar#sh ip int br | i up
FastEthernet0/0       YES NVRAM 
up                    up
