How to Fix CVE-2022-24723

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

urijs fixed: 1.19.9 
npm install urijs@1.19.9
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 urijs

How to Check if You Are Affected

To determine whether your Node.js application is affected by CVE-2022-24723, inspect your project dependencies using npm:

npm ls urijs

Analyze the terminal output to locate any version of Urijs in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 1.19.9), your application is affected.

Note: The npm ls urijs 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 Urijs, 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 Whitespace characters are not removed from the beginning of the protocol, so URLs are not parsed properly and protocol validation mechanisms may fail. ### Patches Patched in 1.19.9 ### Workarounds Remove leading whitespace from values before passing them to URI.parse (e.g. via `.href(value)` or `new URI(value)`), e.g. by using ```js function remove_whitespace(url){ const whitespace = /^[\x00-\x20\u00a0\u1680\u2000-\u200a\u2028\u2029\u202f\u205f\u3000\ufeff]+/; url = url.replace(whitespace, '') return url } ``` ### References * https://huntr.dev/bounties/82ef23b8-7025-49c9-b5fc-1bb9885788e5/ ### For more information If you have any questions or comments about this advisory: * Open an issue in [medialize/URI.js](https://github.com/medialize/URI.js/)
