CVE-2018-6794
5.3 · MEDIUMOverview
CVE-2018-6794 is a medium-severity vulnerability affecting suricata-ids suricata. It was published on February 7, 2018 and has a CVSS 3.0 base score of 5.3 (MEDIUM).
This vulnerability has a CVSS 3.0 base score of 5.3, rated MEDIUM. It can be exploited remotely over the network. No authentication or special privileges are required for exploitation.
Technical Description
Suricata before 4.0.4 is prone to an HTTP detection bypass vulnerability in detect.c and stream-tcp.c. If a malicious server breaks a normal TCP flow and sends data before the 3-way handshake is complete, then the data sent by the malicious server will be accepted by web clients such as a web browser or Linux CLI utilities, but ignored by Suricata IDS signatures. This mostly affects IDS signatures for the HTTP protocol and TCP stream content; signatures for TCP packets will inspect such network traffic as usual.
Remediation
Check the references section for vendor advisories and patches from suricata-ids. Update suricata to the latest patched version. If immediate patching is not possible, review the CVSS vector to understand the attack surface and apply compensating controls such as network segmentation or access restrictions.
