[//]: # (werk v2) # kaspersky_av: Don't run kav4fs-control or kesl-control if they aren't owned by root key | value ---------- | --- date | 2024-02-27T09:14:50+00:00 version | 2.4.0b1 class | security edition | cre component | checks level | 1 compatible | yes Kaspersky Anti-Virus plugin uses /opt/kaspersky/kav4fs/bin/kav4fs-control and /opt/kaspersky/kesl/bin/kesl-control commands to monitor a Kaspersky Anti-Virus installation. To prevent privilege escalation, the plugin (which is run by root user) must not run executables which can be changed by less privileged users. In the default installation, kav4fs-control and kesl-control commands are owned by root and root is the only user with write permissions, which prevents privilege escalation attacks. With this Werk, the plugin checks if control commands are owned by root and root is the only user with write permissions before running the command. If that's not the case the commands won't be run. This prevents privilege escalation attacks if the permissions of the control commands have been changed. We rate this with a CVSS of 0 (None) (CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:N). This CVSS is primarily meant to please automatic scanners.
