Cross-site scripting (XSS) vulnerability in Cisco IOS Web Server for IOS 12.0(2a) allows remote attackers to inject arbitrary web script or HTML by (1) packets containing HTML that an administrator views via an HTTP interface to the contents of memory buffers, as demonstrated by the URI /level/15/exec/-/buffers/assigned/dump; or (2) sending the router Cisco Discovery Protocol (CDP) packets with HTML payload that an administrator views via the CDP status pages. NOTE: these vectors were originally reported as being associated with the dump and packet options in /level/15/exec/-/show/buffers.

Security readout for executives and security teams

This is an old Cisco IOS Web Server cross-site scripting issue. An attacker could place HTML or script into data that a router administrator later views in the web interface. Business risk depends on whether affected IOS web management is still enabled on legacy devices. Likely exposure is legacy Cisco IOS devices with the IOS HTTP server enabled and administrators using the affected web pages. The source bundle names IOS 12.0(2a), while the structured affected-product fields are n/a, so scope should be confirmed against Cisco guidance and inventory data. Treat this as a legacy network-device hygiene issue unless affected IOS web management is still present. If confirmed on production routers, prioritize remediation because compromise of administrator browser context can support credential or session abuse. Mitigation focus: Check Cisco advisory guidance for affected IOS releases and fixed software.; Disable the IOS HTTP server where web management is not required.; Restrict router management access to trusted administrative networks only..
