Vanilla · Vanilla Cms · CVE-2006-3850
**Name of the Vulnerable Software and Affected Versions**
Vanilla CMS versions 1.0.1 and earlier
**Description**
The issue concerns a remote file inclusion vulnerability in the upgrader.php file of Vanilla CMS. This vulnerability can be exploited when the /conf/old settings.php file exists, allowing remote attackers to execute arbitrary PHP code via a URL in the `RootDirectory` parameter. However, the vulnerability has been disputed for version 1.0, and it is unclear whether older versions are affected.
**Recommendations**
For Vanilla CMS versions 1.0.1 and earlier, consider restricting access to the upgrader.php file and the /conf/old settings.php file to minimize the risk of exploitation. As a temporary workaround, avoid using the `RootDirectory` parameter in the affected API endpoint until the issue is resolved. At the moment, there is no information about a newer version that contains a fix for this vulnerability.
