CVE-2011-4810

Name of the Vulnerable Software and Affected Versions WHMCS versions 3.x through 4.x

Description The issue allows remote attackers to read arbitrary files. This is achieved through multiple directory traversal vulnerabilities. Specifically, the templatefile parameter in submitticket.php and downloads.php, and the report parameter to admin/reports.php are vulnerable.

Recommendations For WHMCS versions 3.x through 4.x, consider restricting access to the submitticket.php, downloads.php, and admin/reports.php endpoints until a fix is available. As a temporary workaround, avoid using the templatefile and report parameters in these endpoints to minimize the risk of exploitation.
