# CVE-2021-25630: "loolforkit" is a privileged program that is supposed to be run by a special, non-privileged "lool" user.

- Severity: no CVSS score reported
- Known exploited (CISA KEV): no
- Fixed in: 4.2.13, 6.4.3
- Published: 2021-02-23 · Updated: 2024-09-16

## Affected

- Collabora Productivity Collabora Online: from Collabora Online 4.2, fixed in 4.2.13; from Collabora Online 6.4, fixed in 6.4.3
- The Document Foundation LibreOffice Online: through 7.0.1.1

## Description

"loolforkit" is a privileged program that is supposed to be run by a special, non-privileged "lool" user. Before doing anything else "loolforkit" checks, if it was invoked by the "lool" user, and refuses to run with privileges, if it's not the case. In the vulnerable version of "loolforkit" this check was wrong, so a normal user could start "loolforkit" and eventually get local root privileges.

## What to do

- Check your stack: if you ship or depend on Collabora Productivity Collabora Online, The Document Foundation LibreOffice Online, upgrade to a fixed version (4.2.13, 6.4.3) per the references below.
