Unknown · Whois Search · CVE-2011-5194
**Name of the Vulnerable Software and Affected Versions**
Whois Search plugin versions prior to 1.4.2.3
**Description**
A cross-site scripting (XSS) issue allows remote attackers to inject arbitrary web script or HTML via the `domain` parameter in the vendors/samswhois/samswhois.inc.php file. This enables attackers to execute malicious scripts on the client-side.
**Recommendations**
For versions prior to 1.4.2.3, update to version 1.4.2.3 or later to resolve the issue. As a temporary workaround, consider restricting access to the vulnerable `samswhois.inc.php` file until a patch is applied. Avoid using the `domain` parameter in the affected API endpoint until the issue is resolved.
