How to Fix CVE-2022-24375

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

node-opcua fixed: 2.74.0 
npm install node-opcua@2.74.0
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 node-opcua

How to Check if You Are Affected

To determine whether your Node.js application is affected by CVE-2022-24375, inspect your project dependencies using npm:

npm ls node-opcua

Analyze the terminal output to locate any version of Node opcua in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 2.74.0), your application is affected.

Note: The npm ls node-opcua 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-400: Uncontrolled Resource Consumption, where the product does not properly control the allocation and maintenance of a limited resource. In Node opcua, 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

The package node-opcua before 2.74.0 are vulnerable to Denial of Service (DoS) when bypassing the limitations for excessive memory consumption by sending multiple `CloseSession` requests with the `deleteSubscription` parameter equal to `False`.
