CVE-2017-16667

HIGH 7.8EPSS 1.46%

Does this matter?

High impact if exploited, but EPSS currently rates exploitation as unlikely (1.46%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.

Description

backintime (aka Back in Time) before 1.1.24 did improper escaping/quoting of file paths used as arguments to the 'notify-send' command, leading to some parts of file paths being executed as shell commands within an os.system call in qt4/plugins/notifyplugin.py. This could allow an attacker to craft an unreadable file with a specific name to run arbitrary shell commands.
