CSRF in Murasoftware Mura Cms

CVE-2025-55040

The import form CSRF vulnerability in MuraCMS through 10.1.10 allows attackers to upload and install malicious form definitions through a CSRF attack. The vulnerable cForm.importform function lacks CSRF token validation, enabling malicious websites to forge file upload requests that install attacker-controlled forms when an authenticated administrator visits a crafted webpage. Full exploitation of this vulnerability would require the victim to select a malicious ZIP file containing form definitions, which can be automatically generated by the exploit page and used to create data collection forms that steal sensitive information. Successful exploitation of the import form CSRF vulnerability could result in the installation of malicious data collection forms on the target MuraCMS website that can steal sensitive user information. When an authenticated administrator visits a malicious webpage containing the CSRF exploit and selects the attacker-generated ZIP file, their browser uploads and installs form definitions that create legitimate forms that could be designed with malicious content.
