Advisory Details:
Depth Security discovered a vulnerability in Solarwinds Virtualization Manager appliance.
This attack requires a user to have an operating system shell on the vulnerable appliance.
1) Misconfiguration of sudo in Solarwinds Virtualization Manager: CVE-2016-3643
The vulnerability exists due to the miconfiguration of sudo in that it allows any local user to use sudo to execute commands as the superuser.
A local attacker can obtain root privileges to the operating system regardless of privilege level.
-----------------------------------------------------------------------------------------------
Solution:
Solarwinds has released a hotfix to remediate this vulnerability on existing installations.
This flaw as well as several others have been corrected and that release has been put into manufacturing for new appliances.
-----------------------------------------------------------------------------------------------
Proof of Concept:
The following is an example of the commands necessary for a low-privileged user to dump the contents of the "/etc/shadow" file by using sudo.
sudo cat /etc/passwd
