How to Fix CVE-2024-28849

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

follow-redirects fixed: 1.15.6 
npm install follow-redirects@1.15.6
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 follow-redirects

How to Check if You Are Affected

To determine whether your Node.js application is affected by CVE-2024-28849, inspect your project dependencies using npm:

npm ls follow-redirects

Analyze the terminal output to locate any version of Follow redirects in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 1.15.6), your application is affected.

Note: The npm ls follow-redirects 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-200: Exposure of Sensitive Information to an Unauthorized Actor, where the product exposes sensitive information to an actor that is not explicitly authorized to have access to that information. In Follow redirects, 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

When using [axios](https://github.com/axios/axios), its dependency follow-redirects only clears authorization header during cross-domain redirect, but allows the proxy-authentication header which contains credentials too. ## Steps To Reproduce & PoC Test code: ```js const axios = require('axios'); axios.get('http://127.0.0.1:10081/', { headers: { 'AuThorization': 'Rear Test', 'ProXy-AuthoriZation': 'Rear Test', 'coOkie': 't=1' } }) .then((response) => { console.log(response); }) ``` When I meet the cross-domain redirect, the sensitive headers like authorization and cookie are cleared, but proxy-authentication header is kept. ## Impact This vulnerability may lead to credentials leak. ## Recommendations Remove proxy-authentication header during cross-domain redirect ### Recommended Patch [follow-redirects/index.js:464](https://github.com/follow-redirects/follow-redirects/commit/c4f847f85176991f95ab9c88af63b1294de8649b) ```diff - removeMatchingHeaders(/^(?:authorization|cookie)$/i, this._options.headers); + removeMatchingHeaders(/^(?:authorization|proxy-authorization|cookie)$/i, this._options.headers); ```
