Technical details
An authenticated Local File Inclusion (LFI) vulnerability exists in the HAXCMS saveOutline endpoint due to improper path validation. The application attempted to mitigate path traversal by using str_replace to remove '../' and './' sequences, but this filter can be bypassed using nested patterns (e.g., '....//'). An attacker with low-privileged credentials can manipulate the 'location' field in the saveOutline API to write arbitrary paths into site.json, subsequently allowing them to read sensitive files like /etc/passwd or application secrets accessible to the web server user. The vulnerability affects both PHP and Node.js backends and is resolved in version 26.0.0.
Affected products
- HAX the Web HAXCMS <= 25.0.0
- HAX the Web @haxtheweb/haxcms-nodejs <= 25.0.0
