CVE-2020-27187: Kde Partition Manager

High severity, CVSS 7.8. EPSS: 0.4% chance of exploitation in the next 30 days.

An issue was discovered in KDE Partition Manager 4.1.0 before 4.2.0. The kpmcore_externalcommand helper contains a logic flaw in which the service invoking D-Bus is not properly checked. An attacker on the local machine can replace /etc/fstab, and execute mount and other partitioning related commands, while KDE Partition Manager is running. the mount command can then be used to gain full root privileges.

Affected products

• Kde Partition Manager: from 4.1.0, before 4.2.0 (fixed in 4.2.0)
