How to Fix CVE-2019-1020012

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

parse-server fixed: 3.4.1 
npm install parse-server@3.4.1
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 parse-server

How to Check if You Are Affected

To determine whether your Node.js application is affected by CVE-2019-1020012, inspect your project dependencies using npm:

npm ls parse-server

Analyze the terminal output to locate any version of Parse server in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 3.4.1), your application is affected.

Note: The npm ls parse-server 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-444: Inconsistent Interpretation of HTTP Requests ('HTTP Request/Response Smuggling'), where the product acts as an intermediary http agent (such as a proxy or firewall) in the data flow between two entities such as a client and server, but it does not interpret malformed http requests or responses in ways that are consistent with how the messages will be processed by those entities that are at the ultimate destination. In Parse server, 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

### Impact If a POST request is made to /parse/classes/_Audience (or other volatile class), any subsuquent POST requests result in an internal server error (500). ### Patches Afflicted installations will also have to remove the offending collection from their database. Yes, patched in 3.4.1 ### Workarounds Yes, user can apply: https://github.com/parse-community/parse-server/commit/8709daf698ea69b59268cb66f0f7cee75b52daa5 ### References Nothing other than this advisory at this time ### For more information If you have any questions or comments about this advisory: * Open an issue in [parse-server](https://github.com/parse-community/parse-server) * Email us at [security@parseplatform.org](mailto:security@parseplatform.org)
