https://notcve.org/view.php?id=CVE-2016-10728
An issue was discovered in Suricata before 3.1.2. If an ICMPv4 error packet is received as the first packet on a flow in the to_client direction, it confuses the rule grouping lookup logic. The toclient inspection will then continue with the wrong rule group. This can lead to missed detection. Se ha descubierto un problema en versiones anteriores a la 3.1.2 de Suricata. • https://github.com/kirillwow/ids_bypass https://lists.debian.org/debian-lts-announce/2018/09/msg00019.html https://redmine.openinfosecfoundation.org/issues/1880 https://suricata-ids.org/2016/09/07/suricata-3-1-2-released • CWE-20: Improper Input Validation •

https://notcve.org/view.php?id=CVE-2018-14568
Suricata before 4.0.5 stops TCP stream inspection upon a TCP RST from a server. This allows detection bypass because Windows TCP clients proceed with normal processing of TCP data that arrives shortly after an RST (i.e., they act as if the RST had not yet been received). Suricata en versiones anteriores a la 4.0.5 detiene la inspección de transmisiones TCP al recibir un TCP RST de un servidor. Esto permite la omisión de la detección debido a que los clientes de Windows TCP continuaban el procesamiento habitual de datos TCP que llegan poco después de un RST (por ejemplo, actúan como si el RST no se hubiese recibido aún). • https://github.com/OISF/suricata/pull/3428/commits/843d0b7a10bb45627f94764a6c5d468a24143345 https://github.com/kirillwow/ids_bypass https://redmine.openinfosecfoundation.org/issues/2501 https://suricata-ids.org/2018/07/18/suricata-4-0-5-available •
CVSS: 5.3EPSS: 59%CPEs: 2EXPL: 1CVE-2018-6794 – Suricata < 4.0.4 - IDS Detection Bypass
https://notcve.org/view.php?id=CVE-2018-6794
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. Suricata en versiones anteriores a la 4.0.4 es propenso a una vulnerabilidad de omisión de detección HTTP en detect.c y stream-tcp.c. Si un servidor malicioso interrumpe un flujo TCP normal y envía datos antes de que se complete el handshake tridireccional, los datos enviados por el servidor malicioso se aceptarán por parte de clientes web como el navegador web o herramientas de interfaz de línea de comandos de Linux, pero las firmas IDS de Suricata los ignorarán. • https://www.exploit-db.com/exploits/44247 https://github.com/OISF/suricata/pull/3202/commits/e1ef57c848bbe4e567d5d4b66d346a742e3f77a1 https://lists.debian.org/debian-lts-announce/2018/12/msg00000.html https://redmine.openinfosecfoundation.org/issues/2427 https://suricata-ids.org/2018/02/14/suricata-4-0-4-available • CWE-693: Protection Mechanism Failure •

Suricata before 1.4.6 allows remote attackers to cause a denial of service (crash) via a malformed SSL record. Suricata anterior a 1.4.6 permite a atacantes remotos causar una denegación de servicio (caída) a través de un registro SSL malformado. • http://secunia.com/advisories/54968 http://suricata-ids.org/2013/09/24/suricata-1-4-6-released https://exchange.xforce.ibmcloud.com/vulnerabilities/87492 • CWE-20: Improper Input Validation •
