Summary
HAX CMS NodeJS Application Has Improper Error Handling That Leads to Denial of Service
Details

Summary

The HAX CMS NodeJS application crashes when an authenticated attacker provides an API request lacking required URL parameters. This vulnerability affects the listFiles and saveFiles endpoints.

Details

This vulnerability exists because the application does not properly handle exceptions which occur as a result of changes to user-modifiable URL parameters.

Affected Resources

• listFiles.js:22 listFiles() • saveFile.js:52 saveFile() • system/api/listFiles • system/api/saveFile

PoC

  1. Targeting an instance of instance of HAX CMS NodeJS, send a request without parameters to listFiles or saveFiles. The following screenshot shows the request in Burp Suite. listfilesrequest

  2. The server will crash with ERR_INVALID_ARG_TYPE. listfilescrash

Impact

An authenticated attacker can deny access to the HAX CMS NodeJS application by crashing the backend server. This prevents all users from accessing the backend system. If the backend system is hosting websites, those websites will be unavailable.

Severity ?
