How to Fix CVE-2015-9544

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

xdlocalstorage fixed: Latest secure release 
npm install xdlocalstorage@Latest secure release
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 xdlocalstorage

How to Check if You Are Affected

To determine whether your Node.js application is affected by CVE-2015-9544, inspect your project dependencies using npm:

npm ls xdlocalstorage

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

Note: The npm ls xdlocalstorage 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 Xdlocalstorage, 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

An issue was discovered in xdLocalStorage through 2.0.5. The receiveMessage() function in xdLocalStoragePostMessageApi.js does not implement any validation of the origin of web messages. Remote attackers who can entice a user to load a malicious site can exploit this issue to impact the confidentiality and integrity of data in the local storage of the vulnerable site via malicious web messages.
