EUVDB-ID: #VU32797

Risk: Low

CVSSv3.1:

CVE-ID: CVE-2012-2337

Description

The vulnerability allows a local non-authenticated attacker to execute arbitrary code.

sudo 1.6.x and 1.7.x before 1.7.9p1, and 1.8.x before 1.8.4p5, does not properly support configurations that use a netmask syntax, which allows local users to bypass intended command restrictions in opportunistic circumstances by executing a command on a host that has an IPv4 address.

Mitigation

Install update from vendor's website.
