Title

Уязвимость драйвера обработки TCP-пакетов систем обнаружения вторжений Snort и Suricata IDS, позволяющая нарушителю обойти функцию обнаружения сетевых атак

Description

Уязвимость драйвера обработки TCP-пакетов систем обнаружения вторжений Snort и Suricata IDS, связана с реализацией внутреннего механизма обработки TCP-соединений. Эксплуатация уязвимости позволяет нарушителю, действующему удалённо, обойти функцию обнаружения сетевых атак, реализуемых при помощи протокола HTTP, путём отправки специально сформированного HTTP-пакета до завершения процедуры установки TCP-соединения

Severity ?

Vendor

Open Information Security Foundation, Cisco Systems Inc.

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.
