What is CVE-2019-16701?

The vulnerability exists in pfSense, where a malicious actor can exploit the way XML documents are processed, specifically by leveraging the 'methodCall' structure. Affected versions permit remote execution of arbitrary PHP code via 'pfsense.exec_php' function calls that include shell metacharacters within parameter values. This could allow an attacker to compromise the system's integrity and execute malicious commands remotely.
