Description

pfBlockerNG is a popular pfSense plugin that is not installed by default. It’s generally used to
block inbound connections from whole countries or IP ranges. Versions 2.1.4_26 and below are affected
by an unauthenticated RCE vulnerability that results in root access. Note that version 3.x is unaffected.
