• Exploited in the wild: not listed in CISA KEV
• EPSS: 0.8% probability of exploitation in the next 30 days
• Public exploit or detection template: none known

• Weakness: CWE-78

Description

An issue was discovered in soliduiserver/deviceserviceaction.cpp in KDE Plasma Workspace before 5.12.0. When a vfat thumbdrive that contains `` or $() in its volume label is plugged in and mounted through the device notifier, it's interpreted as a shell command, leading to a possibility of arbitrary command execution. An example of an offending volume label is "$(touch b)" -- this will create a file called b in the home folder.

Affected products

• Debian Linux: 9.0
• KDE Plasma Workspace: before 5.12.0 — fixed in 5.12.0

How to fix

Upgrade to a fixed version: KDE Plasma Workspace 5.12.0. Check the vendor advisory for mitigations.
