**Name of the Vulnerable Software and Affected Versions**
BackupPC versions 3.0.0 through 3.2.1
**Description**
A cross-site scripting (XSS) issue allows remote attackers to inject arbitrary web script or HTML via the `num` parameter in a view action to "index.cgi", related to the log file viewer.
**Recommendations**
For versions 3.0.0 through 3.2.1, as a temporary workaround, consider restricting access to the "index.cgi" endpoint until a patch is available. Avoid using the `num` parameter in the affected "index.cgi" endpoint until the issue is resolved. At the moment, there is no information about a newer version that contains a fix for this vulnerability.
