**Name of the Vulnerable Software and Affected Versions**
vBulletin versions 3.0.6 and earlier
**Description**
The issue allows remote attackers to execute arbitrary PHP code via nested variables in the `template` parameter when "Add Template Name in HTML Comments" is enabled.
**Recommendations**
For versions 3.0.6 and earlier, disable the "Add Template Name in HTML Comments" option to prevent exploitation.
As a temporary workaround, consider restricting access to the `misc.php` file until a patch is available.
Avoid using nested variables in the `template` parameter until the issue is resolved.
