How to Fix CVE-2024-57075

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

eazy-logger fixed: 4.1.0 
npm install eazy-logger@4.1.0
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 eazy-logger

How to Check if You Are Affected

To determine whether your Node.js application is affected by CVE-2024-57075, inspect your project dependencies using npm:

npm ls eazy-logger

Analyze the terminal output to locate any version of Eazy logger in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 4.1.0), your application is affected.

Note: The npm ls eazy-logger 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 Eazy logger, 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

A prototype pollution in the lib.Logger function of eazy-logger v4.0.1 allows attackers to cause a Denial of Service (DoS) via supplying a crafted payload. 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. Moreover, the consequences of this vulnerability can escalate to other injection-based attacks, depending on how the library integrates within the application. For instance, if the polluted property propagates to sensitive Node.js APIs (e.g., `child_process.exec`, `eval`), it could enable an attacker to execute arbitrary commands within the application's context. ## Proof of Concept ```js (async () => { const lib = await import('eazy-logger'); var someObj = {} console.log("Before Attack: ", JSON.stringify({}.__proto__)); try { // for multiple functions, uncomment only one for each execution. lib.Logger (JSON.parse('{"__proto__":{"pollutedKey":123}}')) } catch (e) { } console.log("After Attack: ", JSON.stringify({}.__proto__)); delete Object.prototype.pollutedKey; })(); ```
