New Privilege Escalation Flaw Affects Most Linux Distributions

An Indian security researcher has discovered a highly critical flaw in X.Org Server package that impacts OpenBSD and most Linux distributions, including Debian, Ubuntu, CentOS, Red Hat, and Fedora.


The flaw, tracked as CVE-2018-14665, was introduced in X.Org server 1.19.0 package that remained undetected for almost two years and could have been exploited by a local attacker on the terminal or via SSH to elevate their privileges on a target system.

The two vulnerable parameters in question are:
  • -modulepath: to set a directory path to search for Xorg server modules,
  • -logfile: to set a new log file for the Xorg server, instead of using the default log file that is located at /var/log/Xorg.n.log on most platforms.

Security researcher Matthew Hickey shared an easy to execute proof-of-concept exploit code earlier today on Twitter, saying "An attacker can literally take over impacted systems with 3 commands or less."

lenovo ThinkPad T530 - MX-18
lenovo s21e - MX-18, antiX-17.3.1 (live-USB)
FYI: mx "test" repo is not the same thing as debian testing repo.
