Linux Distros Unpatched Vulnerability : CVE-2025-24959

low Nessus Plugin ID 261475

Language:

Synopsis

The Linux/Unix host has one or more packages installed with a vulnerability that the vendor indicates will not be patched.

Description

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available.

- zx is a tool for writing better scripts. An attacker with control over environment variable values can inject unintended environment variables into `process.env`. This can lead to arbitrary command execution or unexpected behavior in applications that rely on environment variables for security-sensitive operations. Applications that process untrusted input and pass it through `dotenv.stringify` are particularly vulnerable. This issue has been patched in version 8.3.2. Users should immediately upgrade to this version to mitigate the vulnerability. If upgrading is not feasible, users can mitigate the vulnerability by sanitizing user-controlled environment variable values before passing them to `dotenv.stringify`. Specifically, avoid using ``, `'`, and backticks in values, or enforce strict validation of environment variables before usage. (CVE-2025-24959)

Note that Nessus relies on the presence of the package as reported by the vendor.

Solution

There is no known solution at this time.
