Amazon Linux AMI : sudo, sudo-devel (ALAS-2023-1682)

high Nessus Plugin ID 171020

Language:

Synopsis

The remote Amazon Linux AMI host is missing a security update.

Description

It is, therefore, affected by a vulnerability as referenced in the ALAS-2023-1682 advisory.

 In Sudo before 1.9.12p2, the sudoedit (aka -e) feature mishandles extra arguments passed in the user- provided environment variables (SUDO_EDITOR, VISUAL, and EDITOR), allowing a local attacker to append arbitrary entries to the list of files to process. This can lead to privilege escalation. Affected versions are 1.8.0 through 1.9.12.p1. The problem exists because a user-specified editor may contain a
 -- argument that defeats a protection mechanism, e.g., an EDITOR='vim -- /path/to/extra/file' value.
 (CVE-2023-22809)

Tenable has extracted the preceding description block directly from the tested product security advisory.

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.

Solution

pkg_manager = 'yum'Run ' update sudo' to update your system.
