Rewterz Threat Advisory – Zero-Day Bug in KDE Executes Commands by Opening a Folder

August 7, 2019

Severity

High

Analysis Summary

KDE is vulnerable to a command injection vulnerability in the KDesktopFile class. When a .desktop or .directory file is instantiated, it unsafely evaluates environment variables and shell expansions using KConfigPrivate::expandString() via the KConfigGroup::readEntry() function. Using a specially crafted .desktop file a remote user could be compromised by simply downloading and viewing the file in their file manager, or by drag and dropping a link of it into their documents or desktop.

Impact

Command injection

Affected Vendors

Linux

Affected Products

KDE version 4 and 5

Remediation

It is recommended for users to check any .desktop or .directory files and disable any dynamic entries.
