Hello all, Im looking to find out if anyone has information on the logic behind some of the Snort rules associated with Log4J detection. I can successfully trigger these rules by sending a crafted GET request with a jndi:ldap:// query in the header and then the 5 rules ( 58723 58726 58737 58742 58743 ) are triggered on the Firepower appliance and the packets are dropped but I cannot find anywhere that says WHY the packets are dropped beyond that its detecting rules for Log4J exploitation. The 5 all have the same level of detail listed such as this one https://www.snort.org/rule_docs/1-58723 Any docs or places I missed to look for the details would be super helpful.
