CGI Generic XSS (extended patterns)

medium Nessus Plugin ID 55903

Synopsis

The remote web server is prone to cross-site scripting attacks.

Description

The remote web server hosts one or more CGI scripts that fail to adequately sanitize request strings with malicious JavaScript. By leveraging this issue, an attacker may be able to cause arbitrary HTML and script code to be executed in a user's browser within the security context of the affected site. These XSS vulnerabilities are likely to be 'non-persistent' or 'reflected'.

Solution

Restrict access to the vulnerable application. Contact the vendor for a patch or upgrade.
