The version of engrampa installed on the remote host is prior to 1.24.1-1. It is, therefore, affected by a vulnerability as referenced in the ALAS2MATE-DESKTOP1.X-2024-008 advisory.
Note that Nessus has not tested for this issue but has instead relied only on the application’s self-reported version number.

"The version of engrampa installed on the remote host is prior to 1.24.1-1. It is, therefore, affected by a vulnerability
as referenced in the ALAS2MATE-DESKTOP1.X-2024-008 advisory.
- Engrampa is an archive manager for the MATE environment. Engrampa is found to be vulnerable to a Path
Traversal vulnerability that can be leveraged to achieve full Remote Command Execution (RCE) on the
target. While handling CPIO archives, the Engrampa Archive manager follows symlink, cpio by default will
follow stored symlinks while extracting and the Archiver will not check the symlink location, which leads
to arbitrary file writes to unintended locations. When the victim extracts the archive, the attacker can
craft a malicious cpio or ISO archive to achieve RCE on the target system. This vulnerability was fixed in
commit 63d5dfa. (CVE-2023-52138)
Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version
