Description
Netgate pfSense CE through 2.9.0 contains a php.ini injection vulnerability that allows authenticated users with General Setup privileges to inject directives by submitting an unvalidated timezone value. Attackers can embed a quote and newline to add auto_prepend_file pointing at /var/db/zoneinfo, executing PHP as root after php.ini is regenerated at boot or php-fpm restart.
