How to Fix CVE-2022-23505

To remediate this vulnerability, upgrade all affected Passport wsfed saml2 dependencies to a patched release. Both direct and transitive dependencies should be checked, as frameworks or security libraries may pull in vulnerable versions transitively.

passport-wsfed-saml2 fixed: 4.6.3 
npm install passport-wsfed-saml2@4.6.3
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 passport-wsfed-saml2

How to Check if You Are Affected

To determine whether your Node.js application is affected by CVE-2022-23505, inspect your project dependencies using npm:

npm ls passport-wsfed-saml2

Analyze the terminal output to locate any version of Passport wsfed saml2 in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 4.6.3), your application is affected.

Note: The npm ls passport-wsfed-saml2 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 Passport wsfed saml2, 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

# Overview A remote attacker can bypass WSFed authentication on a website using passport-wsfed-saml2. A successful attack requires that the attacker is in possession of an arbitrary IDP signed WSFed assertion. Depending on the IDP used, fully unauthenticated attacks (e.g without access to a valid user) might also be feasible if generation of a signed message can be triggered. # Am I affected? You are affected if you are using WSFed protocol with the passport-wsfed-saml2 library versions < 4.6.3. SAML2 protocol is not affected. # How do I fix it? Upgrade the library to version 4.6.3. # Will the fix impact my users? No, the fix will not impact your users.
