Description Vincent Danen 2011-10-28 17:24:29 UTC
An XSS flaw was found in BackupPC by Jamie Strandboge.  Quoting his post to oss-security [1]:


While preparing updates to fix CVE-2011-3361 in Ubuntu I discovered
another XSS vulnerability in View.pm when accessing the following URLs
in backuppc:

index.cgi?action=view&type=XferLOG&num=<XSS here>&host=<some host>
index.cgi?action=view&type=XferErr&num=<XSS here>&host=<some host>

A patch to correct the flaw is attached to his email message to oss-security.

This flaw is similar to CVE-2011-3361, which is fixed in BackupPC 3.2.1 (the version currently in Fedora/EPEL).
