7-Zip < 25.00

high Nessus Plugin ID 242639

Synopsis

The remote host is missing a security update.

Description

The version of 7-Zip installed on the remote host is prior to 25.00. It is, therefore, affected by multiple vulnerabilities:

- 7-Zip ZIP File Parsing Directory Traversal Remote Code Execution Vulnerability. This vulnerability allows remote attackers to execute arbitrary code on affected installations of 7-Zip. Interaction with this product is required to exploit this vulnerability but attack vectors may vary depending on the implementation. The specific flaw exists within the handling of symbolic links in ZIP files. Crafted data in a ZIP file can cause the process to traverse to unintended directories. An attacker can leverage this vulnerability to execute code in the context of a service account. (CVE-2025-11001, CVE-2025-11002)

- An error in Z-zip's RAR5 handler's error correction for corrupted items can lead to a buffer overflow, resulting in memory corruption and denial of service.
(CVE-2025-53816)

- A Null pointer dereference in 7-Zip's implementation of the Compound handler can lead to denial of service at specific values. (CVE-2025-53817)

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

Solution

Upgrade to 7-Zip version 25.00 or later.
