[R5] Tenable SecurityCenter devform.php message Parameter Reflected XSS

Medium

Synopsis

SecurityCenter contains a flaw that allows a reflected cross-site scripting (XSS) attack. This flaw exists because the application does not validate the 'message' parameter upon submission to the devform.php script. This may allow an attacker to create a specially crafted request that would execute arbitrary script code in a user's browser within the trust relationship between their browser and the server.

This script was included as part of the development process, but not removed for the final release.

Solution

For existing installations, as an administrative user of the system, remove the 'devform.php' script from the server, or restrict access to the script.

# rm -f /opt/sc4/www/devform.php
