Cisco ThousandEyes Enterprise Agent Virtual Appliance Arbitrary File Read
Posted Aug 18, 2023
Authored by Hank Leininger, Jim Becher | Site korelogic.com

Cisco ThousandEyes Enterprise Agent Virtual Appliance version thousandeyes-va-64-18.04 0.218 has an insecure sudo configuration which permits a low-privilege user to read root-only files via the dig command without a password.

Splunk 6.6.x Local Privilege Escalation
Posted Nov 3, 2017
Authored by Hank Leininger | Site korelogic.com

Splunk version 6.6.x suffers from a local privilege escalation vulnerability. Splunk can be configured to run as a non-root user. However, that user owns the configuration file that specifies the user to run as, so it can trivially gain root privileges.

Solarwinds LEM 6.3.1 Management Shell Arbitrary File Read
Posted Apr 24, 2017
Authored by Hank Leininger, Matthew Bergin | Site korelogic.com

The management shell on Solarwinds Log and Event Manager Virtual Appliance version 6.3.1 allows the end user to edit the MOTD banner displayed during SSH logon. The editor provided for this is nano. This editor has a keyboard mapped function which lets the user import a file from the local file system into the editor. An attacker can abuse this to read arbitrary files within the allowed permissions.

Solarwinds LEM 6.3.1 Shell Escape Command Injection
Posted Apr 24, 2017
Authored by Hank Leininger, Matthew Bergin | Site korelogic.com

Insufficient input validation in the management interface can be leveraged in order to execute arbitrary commands. This can lead to (root) shell access to the underlying operating system on Solarwinds Log and Event Manager Virtual Appliance version 6.3.1.

Solarwinds LEM 6.3.1 Sudo Script Abuse Privilege Escalation
Posted Apr 24, 2017

An attacker can abuse functionality provided by a script which may be run with root privilege in order to elevate privilege on Solarwinds Log and Event Manager Virtual Appliance version 6.3.1.

Solarwinds LEM 6.3.1 Sudo Privilege Escalation
Posted Apr 24, 2017
Authored by Hank Leininger, Matthew Bergin | Site korelogic.com

Due to lax filesystem permissions, an attacker can take control of a hardcoded sudo path in order to execute commands as a privileged user on Solarwinds Log and Event Manager Virtual Appliance version 6.3.1.

SQLite Tempdir Selection
Posted Jul 1, 2016
Authored by Hank Leininger | Site korelogic.com

Usually processes writing to temporary directories do not need to perform readdir() because they control the filenames they create, so setting /tmp/ , /var/tmp/ , etc. to be mode 1733 is a not uncommon UNIX hardening practice. Affected versions of SQLite reject potential tempdir locations if they are not readable, falling back to '.'. Thus, SQLite will favor e.g. using cwd for tempfiles on such a system, even if cwd is an unsafe location. Notably, SQLite also checks the permissions of '.', but ignores the results of that check. All versions of SQLite prior to 3.13.0 are affected.

Arris DG1670A Cable Modem Remote Command Execution
Posted Feb 13, 2016
Authored by Hank Leininger, Matthew Bergin | Site korelogic.com

The Arris DG1670A leverages a combination of technologies to deliver the product functionality. Combining several of these technologies in an unanticipated way will allow an attacker to execute arbitrary commands on the underlying operating system as the most privileged user.

hap-linux-2.2.26-1.diff
Posted May 1, 2004
Authored by Hank Leininger | Site TheAIMSGroup.com

HAP-Linux is a collection of security related patches which are designed to be applied after Solar Designers Openwall patches are installed. Changes include some extra information in the printks, and the ability to allow hard links to files you don't own which are in your group, and the ability to follow links & pipes in +t directories if they are not world-writable. This is useful for getting various daemons to run chrooted as a non-root user, and some secure drop- directory stuff.

Changes: This release has been synchronized with kernel 2.2.26 and Openwall 2.2.26-ow1.

Changes: Now has logging of open directory FDs by chrooting processes, and various chroot capability dropping changes and fixes. Split fatal-signal logging into two buckets, so an attacker could not trigger log-throttling by causing an unprivileged segfault right before attacking privileged processes.

Changes: Includes Solar Designer's Openwall 2.2.20-ow2, fixing a Linux kernel vulnerability that allows users to kill any process. There are also fixes to the capabilities dropping of chroot(2). The cap_to_mask stuff was biffed, and now actually works.
