Smoothwall · Smoothwall Express · CVE-2011-5283
**Name of the Vulnerable Software and Affected Versions**
Smoothwall Express versions 3.0 SP3 and earlier, Smoothwall Express version 3.1
**Description**
A cross-site scripting (XSS) issue exists in the web management interface, specifically in the httpd/cgi-bin/ipinfo.cgi file. This allows remote attackers to inject arbitrary web script or HTML via the `IP` parameter in a "Run" action.
**Recommendations**
For Smoothwall Express versions 3.0 SP3 and earlier, and version 3.1, consider restricting access to the ipinfo.cgi file until a patch is available.
As a temporary workaround, avoid using the `IP` parameter in the affected API endpoint until the issue is resolved.
