Vulnerability / Software Security
Multiple security vulnerabilities have been discovered in the open-source Netgate pfSense firewall solution called pfSense that could be chained by an attacker to execute arbitrary commands on susceptible appliances. The issues relate to two reflected cross-site scripting ( XSS ) bugs and one command injection flaw, according to new findings from Sonar. "Security inside a local network is often more lax as network administrators trust their firewalls to protect them from remote attacks," security researcher Oskar Zeino-Mahmalat said . "Potential attackers could have used the discovered vulnerabilities to spy on traffic or attack services inside the local network." Impacting pfSense CE 2.7.0 and below and pfSense Plus 23.05.1 and below, the shortcomings could be weaponized by tricking an authenticated pfSense user (i.e., an admin user) into clicking on a specially crafted URL, which contains an XSS payload that activates command injection.
