Summaryinfo

A vulnerability labeled as critical has been found in Node.js. This vulnerability affects unknown code of the component WebAssembly Export Name Handler. The manipulation results in code injection. This vulnerability is reported as CVE-2023-39333. No exploit exists. The affected component should be upgraded.

Detailsinfo

A vulnerability was found in Node.js (JavaScript Library) (the affected version unknown). It has been classified as critical. Affected is an unknown part of the component WebAssembly Export Name Handler. The manipulation with an unknown input leads to a code injection vulnerability. CWE is classifying the issue as CWE-94. The product constructs all or part of a code segment using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify the syntax or behavior of the intended code segment. This is going to have an impact on confidentiality, integrity, and availability. CVE summarizes:

Maliciously crafted export names in an imported WebAssembly module can inject JavaScript code. The injected code may be able to access data and functions that the WebAssembly module itself does not have access to, similar to as if the WebAssembly module was a JavaScript module. This vulnerability affects users of any active release line of Node.js. The vulnerable feature is only available if Node.js is started with the `--experimental-wasm-modules` command line option.

The weakness was disclosed 10/16/2023. The advisory is available at bugzilla.redhat.com. This vulnerability is traded as CVE-2023-39333 since 07/28/2023. The technical details are unknown and an exploit is not available. This vulnerability is assigned to T1059 by the MITRE ATT&CK project.

The vulnerability scanner Nessus provides a plugin with the ID 216256 (Oracle Linux 8 : nodejs:20 (ELSA-2025-1351)), which helps to determine the existence of the flaw in a target environment.

Upgrading eliminates this vulnerability. The upgrade is hosted for download at nodejs.org.
