QNAP QTS / QuTS hero Vulnerability in sudo (QSA-23-11)

high Nessus Plugin ID 173793

Language:

Synopsis

The remote device is missing a vendor-supplied security patch.

Description

The version of QNAP QTS / QuTS hero installed on the remote host is affected by a vulnerability as referenced in the QSA-23-11 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)

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