This Metasploit module attempts to gain root privileges with SUID Xorg X11 server versions 1.19.0 up to 1.20.3. A permission check flaw exists for -modulepath and -logfile options when starting Xorg. This allows unprivileged users that can start the server the ability to elevate privileges and run arbitrary code under root privileges. This Metasploit module has been tested with OpenBSD 6.3, 6.4, and CentOS 7 (1708). CentOS default install will require console auth for the users session. Cron launches the payload so if Selinux is enforcing exploitation may still be possible, but the module will bail. Xorg must have SUID permissions and may not start if running. On exploitation a crontab.old backup file will be created by Xorg. This Metasploit module will remove the .old file and restore crontab after successful exploitation. Failed exploitation may result in a corrupted crontab. On successful exploitation artifacts will be created consistent with starting Xorg and running a cron.

4d88194aa227646df970e71a08943de5Red Hat Security Advisory 2016-0466-01 - OpenSSH is OpenBSD's SSH protocol implementation. These packages include the core files necessary for both the OpenSSH client and server. It was discovered that the OpenSSH server did not sanitize data received in requests to enable X11 forwarding. An authenticated client with restricted SSH access could possibly use this flaw to bypass intended restrictions. It was discovered that the OpenSSH sshd daemon did not check the list of keyboard-interactive authentication methods for duplicates. A remote attacker could use this flaw to bypass the MaxAuthTries limit, making it easier to perform password guessing attacks.

These packages include the core files necessary for both the OpenSSH client and server. It was discovered that the OpenSSH server did not sanitize data received in requests to enable X11 forwarding. An authenticated client with restricted SSH access could possibly use this flaw to bypass intended restrictions. An access flaw was discovered in OpenSSH; the OpenSSH client did not correctly handle failures to generate authentication cookies for untrusted X11 forwarding. A malicious or compromised remote X application could possibly use this flaw to establish a trusted connection to the local X server, even if only untrusted X11 forwarding was requested.

These packages include the core files necessary for both the OpenSSH client and server. An information leak flaw was found in the way the OpenSSH client roaming feature was implemented. A malicious server could potentially use this flaw to leak portions of memory of a successfully authenticated OpenSSH client. A buffer overflow flaw was found in the way the OpenSSH client roaming feature was implemented. A malicious server could potentially use this flaw to execute arbitrary code on a successfully authenticated OpenSSH client if that client used certain non-default configuration options.

These packages include the core files necessary for both the OpenSSH client and server. A flaw was found in the way OpenSSH handled PAM authentication when using privilege separation. An attacker with valid credentials on the system and able to fully compromise a non-privileged pre-authentication process using a different flaw could use this flaw to authenticate as other users. A use-after-free flaw was found in OpenSSH. An attacker able to fully compromise a non-privileged pre-authentication process using a different flaw could possibly cause sshd to crash or execute arbitrary code with root privileges.

abcf35a318f88ee51e0aae5b82ba1757This Metasploit module exploits a code execution flaw in Western Digital Arkeia version 11.0.12 and below. The vulnerability exists in the 'arkeiad' daemon listening on TCP port 617. Because there are insufficient checks on the authentication of all clients, this can be bypassed. Using the ARKFS_EXEC_CMD operation it's possible to execute arbitrary commands with root or SYSTEM privileges. The daemon is installed on both the Arkeia server as well on all the backup clients. The module has been successfully tested on Windows, Linux, OSX, FreeBSD and OpenBSD.
