How to Fix CVE-2024-32966

To remediate this vulnerability, upgrade all affected Static web 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.

static-web-server fixed: 2.30.0 
Upgrade static-web-server to 2.30.0
Verify Direct and Transitive Dependencies

Run the following command in your project directory to verify that all resolved dependencies use the patched release: 

inspect dependencies for static-web-server

How to Check if You Are Affected

To determine whether your application is affected by CVE-2024-32966, inspect your project dependencies for Static web server:

inspect dependencies for static-web-server

Analyze the terminal output to locate any version of Static web server in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 2.30.0), your application is affected.

Note: Verify declared build manifests and deployed runtime container environments.

Technical Details

Vulnerability Mechanism & Technical Analysis

This vulnerability is classified under CWE-80: Improper Neutralization of Script-Related HTML Tags in a Web Page (Basic XSS), where the product receives input from an upstream component, but it does not neutralize or incorrectly neutralizes special characters such as "<", ">", and "&" that could be interpreted as web-scripting elements when they are sent to a downstream component that processes web pages. In Static web 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

### Summary If directory listings are enabled for a directory that an untrusted user has upload privileges for, a malicious file name like `<img src=x onerror=alert(1)>.txt` will allow JavaScript code execution in the context of the web server’s domain. ### Details SWS generally does not perform escaping of HTML entities on any values inserted in the directory listing. At the very least `file_name` and `current_path` could contain malicious data however. `file_uri` could also be malicious but the relevant scenarios seem to be all caught by hyper. ### Impact For any web server that allow users to upload files or create directories under a name of their choosing this becomes a stored XSS vulnerability.
