CVE-2013-2776
4.4 · MEDIUMOverview
CVE-2013-2776 is a medium-severity vulnerability affecting todd_miller sudo. It was published on April 8, 2013 and has a CVSS 2.0 base score of 4.4 (MEDIUM).
This vulnerability has a CVSS 2.0 base score of 4.4, rated MEDIUM. It requires local or adjacent network access to exploit. No authentication or special privileges are required for exploitation.
Technical Description
sudo 1.3.5 through 1.7.10p5 and 1.8.0 through 1.8.6p6, when running on systems without /proc or the sysctl function with the tty_tickets option enabled, does not properly validate the controlling terminal device, which allows local users with sudo permissions to hijack the authorization of another terminal via vectors related to connecting to the standard input, output, and error file descriptors of another terminal. NOTE: this is one of three closely-related vulnerabilities that were originally assigned CVE-2013-1776, but they have been SPLIT because of different affected versions.
Remediation
Check the references section for vendor advisories and patches from todd_miller. Update sudo to the latest patched version. If immediate patching is not possible, review the CVSS vector to understand the attack surface and apply compensating controls such as network segmentation or access restrictions.
