Cross Site Scripting (XSS) vulnerability in Netgate pf Sense 2.4.4-Release-p3 and Netgate ACME package 0.6.3 allows remote attackers to to run arbitrary code via the RootFolder field to acmecertificateedit.php page of the ACME package.
pfSense through 2.3.4 through 2.4.4-p3 allows Remote Code Injection via a methodCall XML document with a pfsense.execphp call containing shell metacharacters in a parameter value.
In pfSense 2.4.4-p2 and 2.4.4-p3, if it is possible to trick an authenticated administrator into clicking on a button on a phishing page, an attacker can leverage XSS to upload arbitrary executable code, via diagcommand.php and rrdfetchjson.php (timePeriod parameter), to a server. Then, the remote attacker can run any command with root privileges on that server.
In pfSense 2.4.4-p3, a stored XSS vulnerability occurs when attackers inject a payload into the Name or Description field via an acmeaccountkeysedit.php action. The vulnerability occurs due to input validation errors.
