Description
django-pyas2 through 1.2.3 is vulnerable to OS command injection via the cmd_receive and cmd_send fields on the Partner model. These fields are passed directly to os.system() in pyas2/utils.py without sanitization, allowing an authenticated admin user to execute arbitrary commands on the server when an AS2 message is received or sent.
