Suricata generic detection bypass using TCP urgent support
Summary
Suricata generic detection bypass using TCP urgent support
Original description
The description as published by the source.
Suricata is a network Intrusion Detection System, Intrusion Prevention System and Network Security Monitoring engine. Prior to 7.0.8, TCP streams with TCP urgent data (out of band data) can lead to Suricata analyzing data differently than the applications at the TCP endpoints, leading to possible evasions. Suricata 7.0.8 includes options to allow users to configure how to handle TCP urgent data. In IPS mode, you can use a rule such as drop tcp any any -> any any (sid:1; tcp.flags:U*;) to drop all the packets with urgent flag set.
