How to Fix CVE-2024-57077

To remediate this vulnerability, upgrade all affected Utils extend dependencies to a patched release. Both direct and transitive dependencies should be checked, as frameworks or security libraries may pull in vulnerable versions transitively.

utils-extend fixed: Latest secure release 
npm install utils-extend@Latest secure release
Verify Direct and Transitive Dependencies

Run the following command in your project directory to verify that all resolved dependencies use the patched release: 

npm ls utils-extend

How to Check if You Are Affected

To determine whether your Node.js application is affected by CVE-2024-57077, inspect your project dependencies using npm:

npm ls utils-extend

Analyze the terminal output to locate any version of Utils extend in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than the patched release), your application is affected.

Note: The npm ls utils-extend command inspects dependencies declared in your package.json and lockfile; it does not perform automated runtime dynamic scanning.

Technical Details

Vulnerability Mechanism & Technical Analysis

This vulnerability is classified under CWE-1321: Improperly Controlled Modification of Object Prototype Attributes ('Prototype Pollution'), where the product receives input from an upstream component that specifies attributes that are to be initialized or updated in an object, but it does not properly control modifications of attributes of the object prototype. In Utils extend, software state validation or input boundaries are circumvented during processing. Review the official source advisory statement below for specific affected components, classes, and reproduction details.

Source Advisory Statement

The latest version of utils-extend (1.0.8) is vulnerable to Prototype Pollution through the entry function(s) lib.extend. An attacker can supply a payload with Object.prototype setter to introduce or modify properties within the global prototype chain, causing denial of service (DoS) a the minimum consequence. ## PoC ```js async function exploit() { const utilsextend = require(\"utils-extend\"); const payload = JSON.parse('{\"__proto__\":{\"exploited\":true}}'); const result = await utilsextend.extend({}, payload); } await exploit(); ```
