Unknown · Webcalendar · CVE-2006-2762
**Name of the Vulnerable Software and Affected Versions**
WebCalendar version 1.0.3
**Description**
The issue allows remote attackers to execute arbitrary PHP code via a URL in the `includedir` parameter. This parameter is used in an `fopen` call, and the results are used to define a `user inc` setting that is then used in an `include once` call.
**Recommendations**
For WebCalendar version 1.0.3, consider restricting access to the `includes/config.php` file to minimize the risk of exploitation. As a temporary workaround, avoid using the `includedir` 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.
