AI-analyzed exploit summary This Metasploit module exploits a privilege escalation vulnerability in Xorg X11 server on IBM AIX systems by overwriting /etc/passwd to create a root user. It leverages flawed permission checks in the -modulepath and -logfile options.
Description
A flaw was found in xorg-x11-server before 1.20.3. An incorrect permission check for -modulepath and -logfile options when starting Xorg. X server allows unprivileged users with the ability to log in to the system via physical console to escalate their privileges and run arbitrary code under root privileges.

This exploit leverages CVE-2018-14665 to escalate privileges on Solaris 11 by abusing incorrect permission checks in xorg-x11-server for -modulepath and -logfile options. It modifies /etc/inittab to execute a setuid shell, granting root access.
This exploit leverages incorrect command-line parameter validation in the Xorg X server on AIX to overwrite /etc/passwd, creating a new user with root privileges. It uses the '-config' and '-logfile' arguments to inject malicious content into the passwd file.
This exploit leverages CVE-2018-14665 to escalate privileges to root by abusing the -modulepath option in Xorg. It compiles a malicious shared library that spawns a root shell when loaded by the X server.
This exploit leverages CVE-2018-14665 to escalate privileges on RHEL 7 systems by abusing Xorg's file permissions to overwrite /etc/crontab and execute a payload as root. It requires a non-root user to be logged in via console.
This exploit leverages CVE-2018-14665 in xorg-x11-server (1.19.0-1.20.2) to escalate privileges to root on OpenBSD by abusing incorrect permission checks for -modulepath and -logfile options. It injects a malicious cron job to compile and set a setuid root shell.
This exploit leverages CVE-2018-14665 to overwrite the /etc/master.passwd file on OpenBSD systems by abusing the Xorg server's -fp and -logfile options, allowing local privilege escalation to root.
This repository contains a functional local privilege escalation (LPE) exploit for CVE-2018-14665, targeting Xorg X Server versions 1.19.0 to 1.20.2 on OpenBSD 6.3 and 6.4. The exploit abuses the -logfile parameter to overwrite /etc/master.passwd with a root user entry, allowing password-based root access.
This is a functional local privilege escalation (LPE) exploit for CVE-2018-14665, targeting Xorg server versions < 1.20.1 on RHEL 7. It leverages improper file permissions to overwrite /etc/crontab and execute arbitrary commands as root.
This repository contains functional exploit code for CVE-2018-14665, targeting Xorg's -logfile and -modulepath vulnerabilities for local privilege escalation on Solaris and OpenBSD. The exploits are well-documented and include multiple variants for different architectures and environments.
This Metasploit module exploits a privilege escalation vulnerability in Xorg X11 Server (CVE-2018-14665) by leveraging improper permission checks on the -modulepath and -logfile options to overwrite /etc/crontab and execute arbitrary code as root.
This Metasploit module exploits a privilege escalation vulnerability in Xorg X11 server (CVE-2018-14665) by leveraging improper permission checks on the -modulepath and -logfile options. It compiles a shared object to gain root privileges via a malicious constructor function.
This Metasploit module exploits a permission check flaw in Xorg X11 Server on AIX systems, allowing local privilege escalation by overwriting /etc/passwd to create a root user. It leverages the -modulepath and -logfile options to inject malicious configurations.
