5DescriptionGitHub Advisory
HAX CMS PHP allows users to manage their microsite universe with a PHP backend. Prior to version 11.0.0, an authenticated Local File Inclusion (LFI) vulnerability in the HAXCMS saveOutline endpoint allows a low-privileged user to read arbitrary files on the server by manipulating the location field written into site.json. This enables attackers to exfiltrate sensitive system files such as /etc/passwd, application secrets, or configuration files accessible to the web server (www-data). The vulnerability stems from the way the HAXCMS backend handles the location field in the site's outline. When a user sends a POST request to /system/api/saveOutline, the backend stores the provided location value directly into the site.json file associated with the site, without validating or sanitizing the input. Later the location parameter is interpreted by the CMS to resolve and load the content for a given node. If the location field contains a relative path like ../../../etc/passwd, the application will attempt to read and render that file. Version 11.0.0 fixes the issue.

Technical ContextAI
Path traversal allows an attacker to access files outside the intended directory by manipulating file paths with sequences like '../'.
RemediationAI
Validate and sanitize file path inputs. Use a whitelist of allowed files or directories. Implement chroot jails or containerization.
