| CVE-2020-19678 | 2 Oisf, Pfsense | 3 Suricata, Pfsense, Suricata Package | 2026-06-17 | N/A | 7.5 HIGH |
| Directory Traversal vulnerability found in Pfsense v.2.1.3 and Pfsense Suricata v.1.4.6 pkg v.1.0.1 allows a remote attacker to obtain sensitive information via the file parameter to suricata/suricata_logs_browser.php. | |||||
| CVE-2019-18792 | 2 Debian, Oisf | 2 Debian Linux, Suricata | 2026-06-17 | 6.4 MEDIUM | 9.1 CRITICAL |
| An issue was discovered in Suricata 5.0.0. It is possible to bypass/evade any tcp based signature by overlapping a TCP segment with a fake FIN packet. The fake FIN packet is injected just before the PUSH ACK packet we want to bypass. The PUSH ACK packet (containing the data) will be ignored by Suricata because it overlaps the FIN packet (the sequence and ack number are identical in the two packets). The client will ignore the fake FIN packet because the ACK flag is not set. Both linux and windows clients are ignoring the injected packet. | |||||
| CVE-2019-18625 | 4 Debian, Linux, Microsoft and 1 more | 4 Debian Linux, Linux Kernel, Windows and 1 more | 2026-06-17 | 5.0 MEDIUM | 7.5 HIGH |
| An issue was discovered in Suricata 5.0.0. It was possible to bypass/evade any tcp based signature by faking a closed TCP session using an evil server. After the TCP SYN packet, it is possible to inject a RST ACK and a FIN ACK packet with a bad TCP Timestamp option. The client will ignore the RST ACK and the FIN ACK packets because of the bad TCP Timestamp option. Both linux and windows client are ignoring the injected packets. | |||||
| CVE-2019-17420 | 2 Oisf, Suricata-ids | 2 Libhtp, Suricata | 2026-06-17 | 5.0 MEDIUM | 5.3 MEDIUM |
| In OISF LibHTP before 0.5.31, as used in Suricata 4.1.4 and other products, an HTTP protocol parsing error causes the http_header signature to not alert on a response with a single \r\n ending. | |||||
| CVE-2019-10050 | 1 Oisf | 1 Suricata | 2026-06-17 | 5.0 MEDIUM | 7.5 HIGH |
| A buffer over-read issue was discovered in Suricata 4.1.x before 4.1.4. If the input of the decode-mpls.c function DecodeMPLS is composed only of a packet of source address and destination address plus the correct type field and the right number for shim, an attacker can manipulate the control flow, such that the condition to leave the loop is true. After leaving the loop, the network packet has a length of 2 bytes. There is no validation of this length. Later on, the code tries to read at an empty position, leading to a crash. | |||||
| CVE-2019-1010279 | 1 Oisf | 1 Suricata | 2026-06-17 | 5.0 MEDIUM | 7.5 HIGH |
| Open Information Security Foundation Suricata prior to version 4.1.3 is affected by: Denial of Service - TCP/HTTP detection bypass. The impact is: An attacker can evade a signature detection with a specialy formed sequence of network packets. The component is: detect.c (https://github.com/OISF/suricata/pull/3625/commits/d8634daf74c882356659addb65fb142b738a186b). The attack vector is: An attacker can trigger the vulnerability by a specifically crafted network TCP session. The fixed version is: 4.1.3. | |||||
| CVE-2019-1010251 | 1 Oisf | 1 Suricata | 2026-06-17 | 5.0 MEDIUM | 7.5 HIGH |
| Open Information Security Foundation Suricata prior to version 4.1.2 is affected by: Denial of Service - DNS detection bypass. The impact is: An attacker can evade a signature detection with a specialy formed network packet. The component is: app-layer-detect-proto.c, decode.c, decode-teredo.c and decode-ipv6.c (https://github.com/OISF/suricata/pull/3590/commits/11f3659f64a4e42e90cb3c09fcef66894205aefe, https://github.com/OISF/suricata/pull/3590/commits/8357ef3f8ffc7d99ef6571350724160de356158b). The attack vector is: An attacker can trigger the vulnerability by sending a specifically crafted network request. The fixed version is: 4.1.2. | |||||
| CVE-2018-10244 | 1 Oisf | 1 Suricata | 2026-06-17 | 7.5 HIGH | 9.8 CRITICAL |
| Suricata version 4.0.4 incorrectly handles the parsing of an EtherNet/IP PDU. A malformed PDU can cause the parsing code to read beyond the allocated data because DecodeENIPPDU in app-layer-enip-commmon.c has an integer overflow during a length check. | |||||
| CVE-2018-10243 | 1 Oisf | 1 Libhtp | 2026-06-17 | 7.5 HIGH | 9.8 CRITICAL |
| htp_parse_authorization_digest in htp_parsers.c in LibHTP 0.5.26 allows remote attackers to cause a heap-based buffer over-read via an authorization digest header. | |||||
| CVE-2018-10242 | 2 Debian, Oisf | 2 Debian Linux, Suricata | 2026-06-17 | 5.0 MEDIUM | 7.5 HIGH |
| Suricata version 4.0.4 incorrectly handles the parsing of the SSH banner. A malformed SSH banner can cause the parsing code to read beyond the allocated data because SSHParseBanner in app-layer-ssh.c lacks a length check. | |||||
| CVE-2018-1000167 | 1 Oisf | 1 Suricata-update | 2026-06-17 | 9.3 HIGH | 7.8 HIGH |
| OISF suricata-update version 1.0.0a1 contains an Insecure Deserialization vulnerability in the insecure yaml.load-Function as used in the following files: config.py:136, config.py:142, sources.py:99 and sources.py:131. The "list-sources"-command is affected by this bug. that can result in Remote Code Execution(even as root if suricata-update is called by root). This attack appears to be exploitable via a specially crafted yaml-file at https://www.openinfosecfoundation.org/rules/index.yaml. This vulnerability appears to have been fixed in 1.0.0b1. | |||||
| CVE-2015-0928 | 1 Oisf | 1 Libhtp | 2026-06-17 | 5.0 MEDIUM | 7.5 HIGH |
| libhtp 0.5.15 allows remote attackers to cause a denial of service (NULL pointer dereference). | |||||
| CVE-2013-5919 | 2 Oisf, Openinfosecfoundation | 2 Suricata, Suricata | 2026-06-16 | 5.0 MEDIUM | N/A |
| Suricata before 1.4.6 allows remote attackers to cause a denial of service (crash) via a malformed SSL record. | |||||
