f2befbe0472fe7eb75d23340eb17531cb6b3aac24075e2066b41f814e12387b2Qualys discovered a vulnerability in OpenSMTPD, OpenBSD's mail server. This vulnerability, an out-of-bounds read introduced in December 2015, is exploitable remotely and leads to the execution of arbitrary shell commands.
2c58b82819510289b2fd55d1c6a82b81b279777abd6a6b0db391f990ec12b148Qualys discovered a minor vulnerability in OpenSMTPD, OpenBSD's mail server. An unprivileged local attacker can read the first line of an arbitrary file (for example, root's password hash in /etc/master.passwd) or the entire contents of another user's file (if this file and /var/spool/smtpd/ are on the same filesystem). A proof of concept exploit is included in this archive.

43925151e6cf6cee1450190c0e9af4dc36b41c12737619edff8bcebdff64e671smtp_mailaddr in smtp_session.c in OpenSMTPD 6.6, as used in OpenBSD 6.6 and other products, allows remote attackers to execute arbitrary commands as root via a crafted SMTP session, as demonstrated by shell meta-characters in a MAIL FROM field. This affects the "uncommented" default configuration. The issue exists because of an incorrect return value upon failure of input validation.
f42f9b3d984851bedec7966cba6c70991ad906a48462064b1ae90325c6aa112bQualys discovered a vulnerability in OpenSMTPD, OpenBSD's mail server. This vulnerability is exploitable since May 2018 (commit a8e222352f, "switch smtpd to new grammar") and allows an attacker to execute arbitrary shell commands, as root.
9415f92980a964e9430ed555502126d19de735d2acfd5db27d83bb342e5a8b2cThis Metasploit module exploits a vulnerability in the OpenBSD ld.so dynamic loader (CVE-2019-19726). The _dl_getenv() function fails to reset the LD_LIBRARY_PATH environment variable when set with approximately ARG_MAX colons. This can be abused to load libutil.so from an untrusted path, using LD_LIBRARY_PATH in combination with the chpass set-uid executable, resulting in privileged code execution. This module has been tested successfully on OpenBSD 6.1 (amd64) and OpenBSD 6.6 (amd64).
3e6540f0f1a2e09ac135f635d113e22b32dffae061cff0c1ae9ba68f036aa0a2Qualys discovered a local privilege escalation in OpenBSD's dynamic loader (ld.so). This vulnerability is exploitable in the default installation (via the set-user-ID executable chpass or passwd) and yields full root privileges. They developed a simple proof of concept and successfully tested it against OpenBSD 6.6 (the current release), 6.5, 6.2, and 6.1, on both amd64 and i386; other releases and architectures are probably also exploitable.
4e1f695e83c851f4826c356e0fbe52865163d4b41d6d1a6675fca7178914287bQualys has discovered that OpenBSD suffers from multiple authentication bypass and local privilege escalation vulnerabilities.
f17dd04f6e2715e22520176b0b9b59af9523bd1f17067f5a5814eb8675c0497dThis Metasploit module has been tested with AIX 7.1 and 7.2, and should also work with 6.1. Due to permission restrictions of the crontab in AIX, this module does not use cron, and instead overwrites /etc/passwd in order to create a new user with root privileges. All currently logged in users need to be included when /etc/passwd is overwritten, else AIX will throw 'Cannot get "LOGNAME" variable' when attempting to change user. The Xorg '-fp' parameter used in the OpenBSD exploit does not work on AIX, and is replaced by '-config', in conjuction with ANSI-C quotes to inject newlines when overwriting /etc/passwd.

bd943879e69498e8031eb6b7f44d08cdc37d59a7ab689aa0b437320c3481fd68This 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.
