What is CVE-2025-49141?

HAX CMS PHP, designed for managing microsite environments, has a critical flaw in its gitImportSite functionality. Prior to version 11.0.3, this feature inadequately validates URLs from POST requests, enabling authenticated attackers to exploit this weakness. By supplying crafted input, attackers can bypass the validation checks of filter_var and strpos, allowing them to execute arbitrary OS commands on the backend server via the proc_open function. The output of these malicious commands can then be exfiltrated through HTTP requests. Users are advised to upgrade to version 11.0.3 or later to mitigate this vulnerability.
