Webcal · Webcal · CVE-2005-4327
**Name of the Vulnerable Software and Affected Versions**
WebCal versions 1.11 through 3.04
**Description**
The issue allows remote attackers to inject arbitrary web script or HTML. This can be achieved via several parameters to webcal.cgi, including the function, year, and date parameters, as well as through new calendar entries and notes for entries.
**Recommendations**
For WebCal versions 1.11 through 3.04, consider restricting access to the webcal.cgi endpoint until a fix is available. As a temporary workaround, avoid using the `function`, `year`, and `date` parameters in the webcal.cgi endpoint. Additionally, restrict the creation of new calendar entries and editing of notes for existing entries to minimize the risk of exploitation. At the moment, there is no information about a newer version that contains a fix for this vulnerability.
