What is CVE-2019-12949?

In pfSense versions 2.4.4-p2 and 2.4.4-p3, an attacker can exploit a vulnerability involving phishing to trick an authenticated administrator into interacting with a malicious page. By clicking on a compromised button, the attacker can perform Cross-Site Scripting (XSS), enabling the upload of arbitrary executable code through the diag_command.php and rrd_fetch_json.php scripts. This exploit allows unrestricted command execution with root privileges on the affected server, posing a significant risk to system integrity and security.

Exploit Proof of Concept (PoC)

PoC code is written by security researchers to demonstrate the vulnerability can be exploited. PoC code is also a key component for weaponization which could lead to ransomware.
