GitHub Vulnerability Alerts

CVE-2024-29041

Impact

Versions of Express.js prior to 4.19.2 and pre-release alpha and beta versions before 5.0.0-beta.3 are affected by an open redirect vulnerability using malformed URLs.

When a user of Express performs a redirect using a user-provided URL Express performs an encode using encodeurl on the contents before passing it to the location header. This can cause malformed URLs to be evaluated in unexpected ways by common redirect allow list implementations in Express applications, leading to an Open Redirect via bypass of a properly implemented allow list.

The main method impacted is res.location() but this is also called from within res.redirect().

Patches

expressjs/express@0867302
expressjs/express@0b74695

An initial fix went out with [email protected], we then patched a feature regression in 4.19.1 and added improved handling for the bypass in 4.19.2.

Workarounds

The fix for this involves pre-parsing the url string with either require('node:url').parse or new URL. These are steps you can take on your own before passing the user input string to res.location or res.redirect.

CVE-2024-43796

Impact

In express <4.20.0, passing untrusted user input - even after sanitizing it - to response.redirect() may execute untrusted code

Patches

this issue is patched in express 4.20.0

Workarounds

users are encouraged to upgrade to the patched version of express, but otherwise can workaround this issue by making sure any untrusted inputs are safe, ideally by validating them against an explicit allowlist

Details

successful exploitation of this vector requires the following:

1. The attacker MUST control the input to response.redirect()
2. express MUST NOT redirect before the template appears
3. the browser MUST NOT complete redirection before:
4. the user MUST click on the link in the template

The code patch appears to update the version of the express package from 4.18.3 to 4.19.2. Here are some points for your code review:

Bug risks:

1. The code patch seems straightforward and is a common practice to update dependencies to their newer versions.
2. Ensure compatibility of the updated express version with other dependencies in your project.

Improvement suggestions:

1. It's essential to verify if any breaking changes have been introduced between versions 4.18.3 and 4.19.2 of Express, as this could impact the functionality of your application.
2. Consider checking release notes or documentation for both versions to understand any additional features, bug fixes, or deprecations that might affect your application.
3. After updating the express package, it's recommended to test thoroughly, including functional and integration testing, to ensure the updated version works correctly with your application.

Overall, updating dependencies is crucial for security patches, performance improvements, and feature enhancements. Just make sure to validate the update by testing your application to avoid unexpected issues before deploying to production.

The code patch you provided is a package.json file where the dependency for Express has been updated from version 4.18.3 to 4.19.2. Here are some of the considerations in this code review:

1. Risk Assessment:

   • Compatibility: Ensure that updating Express does not introduce breaking changes with existing code or other dependencies.
   • Security: Check if there are any known security vulnerabilities associated with the newer version of Express.

2. Improvement Suggestions:

   • Dependency versions: Regularly update dependencies to leverage bug fixes, major features, and security patches.
   • Dependency management: Consider using exact versions (e.g., "4.19.2") instead of ranges unless necessary to prevent unexpected updates that may introduce bugs or compatibility issues.

3. Testing:

   • After updating the dependency, perform thorough testing to verify that the application behaves as expected.
   • Check for regressions and compatibility issues across different environments.

4. Documentation:

   • Update documentation to reflect the changes in dependency versions to help developers understand the project's dependencies.

Remember, always consider your specific project requirements and constraints when making decisions about dependency updates in software development.
