Executive Summary

This vulnerability exists in the Edimax GS-5008PL firmware version 1.00.54 and earlier. It is a stored cross-site scripting (XSS) flaw found in the system_name_set.cgi script. Attackers can exploit this by sending a specially crafted POST request that manipulates the sysName parameter to inject malicious script code. This injected script then executes when administrators view management pages that include system_data.js.

Impact Analysis

The impact of this vulnerability is that an attacker with low privileges can inject and execute arbitrary scripts in the context of the administrator's browser session. This can lead to unauthorized actions performed on behalf of the administrator, potential theft of sensitive information, or manipulation of the device's management interface.
