CVE-2025-54134
HAX CMS NodeJs's Improper Error Handling Leads to Denial of Service
HAX CMS NodeJs allows users to manage their microsite universe with a NodeJs backend. In versions 11.0.8 and below, 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. This vulnerability exists because the application does not properly handle exceptions which occur as a result of changes to user-modifiable URL parameters. This is fixed in version 11.0.9.

HAX CMS NodeJS Application Has Improper Error Handling That Leads to Denial of Service
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
-
Targeting an instance of instance of HAX CMS NodeJS, send a request without parameters to
listFilesorsaveFiles. The following screenshot shows the request in Burp Suite. -
The server will crash with
ERR_INVALID_ARG_TYPE.
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.
