CVE-2010-2956: Sudo 1.7.0 through 1.7.4p3, when a Runas group is configured, does not properly handle use of the -u option...

Security readout for executives and security teams

This is a local privilege escalation flaw in Sudo. On systems running Sudo 1.7.0 through 1.7.4p3 with a Runas group configured, a local user may bypass intended sudo restrictions and gain higher privileges, potentially root. It is not listed as KEV, and the provided sources do not show active exploitation. Likely limited to legacy Unix-like systems that still run Sudo 1.7.0 through 1.7.4p3 and have sudoers rules using Runas groups. Systems without local user access or without this configuration are less directly exposed based on the provided description. Treat this as a high-priority legacy exposure issue where affected systems exist. The business risk is unauthorized elevation from a normal local account to privileged access. Urgency is highest on multi-user servers, administrative jump hosts, and older appliances. Mitigation focus: Identify systems running Sudo 1.7.0 through 1.7.4p3.; Apply vendor Sudo updates from the relevant advisory source.; Review sudoers entries that configure Runas groups..
