How to Fix CVE-2014-10067

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

paypal-ipn fixed: 3.0.0 
npm install paypal-ipn@3.0.0
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 paypal-ipn

How to Check if You Are Affected

To determine whether your Node.js application is affected by CVE-2014-10067, inspect your project dependencies using npm:

npm ls paypal-ipn

Analyze the terminal output to locate any version of Paypal ipn in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 3.0.0), your application is affected.

Note: The npm ls paypal-ipn 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-287: Improper Authentication, where when an actor claims to have a given identity, the product does not prove or insufficiently proves that the claim is correct. In Paypal ipn, 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

Versions 2.x.x and earlier of `paypal-ipn` are affected by a validation bypass vulnerability. paypal-ipn uses the `test_ipn` parameter (which is set by the PayPal IPN simulator) to determine if it should use the production PayPal site or the sandbox. A motivated attacker could craft a request string using the simulator to fool the application into entering the sandbox mode, potentially allowing purchases without valid payment. ## Recommendation Upgrade to version 3.0.0 or later.
