CVE-2023-3099Public exploit

Arbitrary privileged file deletion via D-Bus method

Published Jun 5, 2023 · Updated Aug 2, 2024

Improper access control in Kylin Assistant before 3.0.2-0kylin6k70-23 allows local users to delete arbitrary privileged files. The system D-Bus delete_file method accepts a caller-supplied path and passes it to the privileged system daemon without enforcing authorization. A low-privileged local session can invoke the method without user interaction, enabling system damage or a service interruption.
