BackupPC: Permission bypass via ClientNameAlias by using rsync data backup method

CgiUserConfigEdit in BackupPC 3.1.0, when SSH keys and Rsync are in use in a multi-user environment, does not restrict users from the ClientNameAlias function, which allows remote authenticated users to read and write sensitive files by modifying ClientNameAlias to match another system, then initiating a backup or restore.

Cross-site scripting (XSS) vulnerability in CGI/Browse.pm in BackupPC 3.2.0 and possibly other versions before 3.2.1 allows remote attackers to inject arbitrary web script or HTML via the num parameter in a browse action to index.cgi.

Cross-site scripting (XSS) vulnerability in RestoreFile.pm in BackupPC 3.1.0, 3.2.1, and possibly other earlier versions allows remote attackers to inject arbitrary web script or HTML via the share parameter in a RestoreFile action to index.cgi.

Cross-site scripting (XSS) vulnerability in View.pm in BackupPC 3.0.0, 3.1.0, 3.2.0, 3.2.1, and possibly earlier 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, a different vulnerability than CVE-2011-3361.
