Description:
Hugo Vazquez Carames has reported a vulnerability in Cisco IOS, which can be exploited by malicious people to conduct script insertion attacks.
The vulnerability is caused due to the memory dump feature of the HTTP server not properly sanitising the data in received packets before displaying them to the user in a HTML formatted page when the user views the "/level/15/exec/-/buffers/assigned/dump" link. This can be exploited to execute arbitrary script code in a user's browser session when the user views a memory dump containing malicious Javascript/HTML code from a received packet.
Successful exploitation may allow the attacker to perform certain actions that are accessible by the logon administrator. E.g. changing the "enable" password by injecting HTML code that requests for the "/level/15/configure/-/enable/secret/" link.
The vulnerability has been reported in IOS versions 11.0 through 12.4 with the HTTP server enabled.
