CVE-2025-34097

An unrestricted file upload vulnerability exists in ProcessMaker versions prior to 3.5.4 due to improper handling of uploaded plugin archives. An attacker with administrative privileges can upload a malicious .tar plugin file containing arbitrary PHP code. Upon installation, the plugin’s install() method is invoked, resulting in execution of attacker-supplied PHP code on the server with the privileges of the web server user. This vulnerability can be chained with CVE-2022-38577 — a privilege escalation flaw in the user profile page — to achieve full remote code execution from a low-privileged account.

Summary		(es) Existe una vulnerabilidad de carga de archivos sin restricciones en versiones de ProcessMaker anteriores a la 3.5.4 debido a la gestión incorrecta de los archivos de complementos cargados. Un atacante con privilegios administrativos puede cargar un archivo .tar de complemento malicioso que contenga código PHP arbitrario. Tras la instalación, se invoca el método install() del complemento, lo que provoca la ejecución del código PHP proporcionado por el atacante en el servidor con los privilegios del usuario del servidor web. Esta vulnerabilidad puede vincularse con CVE-2022-38577 (una falla de escalada de privilegios en la página de perfil de usuario) para lograr la ejecución remota completa de código desde una cuenta con pocos privilegios.
