How to Fix CVE-2018-21036

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

sails-hook-sockets fixed: 1.5.5 
npm install sails-hook-sockets@1.5.5
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 sails-hook-sockets

How to Check if You Are Affected

To determine whether your Node.js application is affected by CVE-2018-21036, inspect your project dependencies using npm:

npm ls sails-hook-sockets

Analyze the terminal output to locate any version of Sails hook sockets in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 1.5.5), your application is affected.

Note: The npm ls sails-hook-sockets 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-20: Improper Input Validation, where the product receives input or data, but it does not validate or incorrectly validates that the input has the properties that are required to process the data safely and correctly. In Sails hook sockets, 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

Sails.js before v1.0.0-46 allows attackers to cause a denial of service with a single request because there is no error handler in sails-hook-sockets to handle an empty pathname in a WebSocket request.
