CVE-2018-6794 (GCVE-0-2018-6794)

Vulnerability from cvelistv5 – Published: 2018-02-07 05:00 – Updated: 2024-08-05 06:10

Summary

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.

Severity

No CVSS data available.
