ABB M2M Gateway Improper Privilege Management in embedded Sudo (CVE-2023-22809)

high Tenable OT Security Plugin ID 503257

Synopsis

The remote OT asset is affected by a vulnerability.

Description

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.

This plugin only works with Tenable.ot.
