Base vector

AV:N/AC:M/Au:N/C:C/I:C/A:C

Name of the Vulnerable Software and Affected Versions backintime versions prior to 1.1.24

Description The issue arises from improper escaping/quoting of file paths used as arguments to the 'notify-send' command. This could allow an attacker to craft an unreadable file with a specific name to run arbitrary shell commands within an os.system call in qt4/plugins/notifyplugin.py.

Recommendations For versions prior to 1.1.24, update to version 1.1.24 or later to resolve the issue. As a temporary workaround, consider restricting access to the 'notify-send' command or the notifyplugin.py module to minimize the risk of exploitation.
