HAX CMS NodeJS application Vulnerable to Denial of Service using Malicious Import Request
Source: CVE Program / CVE List V5
Vulnerability Description
HAX CMS helps manage microsite universe with PHP or NodeJs backends. Prior to version 26.0.0, the HAX CMS NodeJS application crashes when an authenticated attacker sends a specially crafted site creation request to the createSite endpoint. A single request is sufficient to take the entire application offline, requiring a manual server restart to restore service. Version 26.0.0 fixes the issue.
