Vim < 9.2.0383 OS Command Injection in netrw (GHSA-85ch-p2qr-m5gx)

medium Nessus Plugin ID 317737

Language:

Synopsis

The remote host is missing a security update.

Description

The version of Vim installed on the remote host is prior to 9.2.0383. It is, therefore, affected by a vulnerability as referenced in the GHSA-85ch-p2qr-m5gx advisory.

- An OS command injection vulnerability exists in the netrw standard plugin bundled with Vim. The suffix extraction logic in s:GetTempfile() allows arbitrary characters after the dot in a filename, permitting shell metacharacters to be embedded in the suffix. Since this temporary file name is passed to external commands without proper escaping, an attacker can inject arbitrary shell commands by inducing a user to open a crafted URL. This vulnerability is fixed in 9.2.0383. (CVE-2026-42307)

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 Vim version 9.2.0383 or later.
