| CVE-2013-5919 | 2 Oisf, Openinfosecfoundation | 2 Suricata, Suricata | 2024-11-21 | 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. | |||||
| CVE-2018-10242 | 2 Debian, Oisf | 2 Debian Linux, Suricata | 2024-10-22 | 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-2019-18792 | 2 Debian, Oisf | 2 Debian Linux, Suricata | 2024-10-22 | 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 | 2024-10-22 | 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-2018-10244 | 1 Oisf | 1 Suricata | 2024-10-22 | 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-2024-47522 | 1 Oisf | 1 Suricata | 2024-10-22 | N/A | 7.5 HIGH |
| Suricata is a network Intrusion Detection System, Intrusion Prevention System and Network Security Monitoring engine. Prior to version 7.0.7, invalid ALPN in TLS/QUIC traffic when JA4 matching/logging is enabled can lead to Suricata aborting with a panic. This issue has been addressed in 7.0.7. One may disable ja4 as a workaround. | |||||
| CVE-2024-47188 | 1 Oisf | 1 Suricata | 2024-10-22 | N/A | 7.5 HIGH |
| Suricata is a network Intrusion Detection System, Intrusion Prevention System and Network Security Monitoring engine. Prior to version 7.0.7, missing initialization of the random seed for "thash" leads to byte-range tracking having predictable hash table behavior. This can lead to an attacker forcing lots of data into a single hash bucket, leading to severe performance degradation. This issue has been addressed in 7.0.7. | |||||
| CVE-2024-47187 | 1 Oisf | 1 Suricata | 2024-10-22 | N/A | 7.5 HIGH |
| Suricata is a network Intrusion Detection System, Intrusion Prevention System and Network Security Monitoring engine. Prior to version 7.0.7, missing initialization of the random seed for "thash" leads to datasets having predictable hash table behavior. This can lead to dataset file loading to use excessive time to load, as well as runtime performance issues during traffic handling. This issue has been addressed in 7.0.7. As a workaround, avoid loading datasets from untrusted sources. Avoid dataset rules that track traffic in rules. | |||||
| CVE-2024-45796 | 1 Oisf | 1 Suricata | 2024-10-22 | N/A | 5.3 MEDIUM |
| Suricata is a network Intrusion Detection System, Intrusion Prevention System and Network Security Monitoring engine. Prior to version 7.0.7, a logic error during fragment reassembly can lead to failed reassembly for valid traffic. An attacker could craft packets to trigger this behavior.This issue has been addressed in 7.0.7. | |||||
| CVE-2024-45795 | 1 Oisf | 1 Suricata | 2024-10-22 | N/A | 7.5 HIGH |
| Suricata is a network Intrusion Detection System, Intrusion Prevention System and Network Security Monitoring engine. Prior to version 7.0.7, rules using datasets with the non-functional / unimplemented "unset" option can trigger an assertion during traffic parsing, leading to denial of service. This issue is addressed in 7.0.7. As a workaround, use only trusted and well tested rulesets. | |||||
| CVE-2024-37151 | 1 Oisf | 1 Suricata | 2024-07-12 | N/A | 7.5 HIGH |
| Suricata is a network Intrusion Detection System, Intrusion Prevention System and Network Security Monitoring engine. Mishandling of multiple fragmented packets using the same IP ID value can lead to packet reassembly failure, which can lead to policy bypass. Upgrade to 7.0.6 or 6.0.20. When using af-packet, enable `defrag` to reduce the scope of the problem. | |||||
| CVE-2024-38534 | 1 Oisf | 1 Suricata | 2024-07-12 | N/A | 7.5 HIGH |
| Suricata is a network Intrusion Detection System, Intrusion Prevention System and Network Security Monitoring engine. Crafted modbus traffic can lead to unlimited resource accumulation within a flow. Upgrade to 7.0.6. Set a limited stream.reassembly.depth to reduce the issue. | |||||
| CVE-2024-38535 | 1 Oisf | 1 Suricata | 2024-07-12 | N/A | 7.5 HIGH |
| Suricata is a network Intrusion Detection System, Intrusion Prevention System and Network Security Monitoring engine. Suricata can run out of memory when parsing crafted HTTP/2 traffic. Upgrade to 6.0.20 or 7.0.6. | |||||
| CVE-2024-38536 | 1 Oisf | 1 Suricata | 2024-07-12 | N/A | 7.5 HIGH |
| Suricata is a network Intrusion Detection System, Intrusion Prevention System and Network Security Monitoring engine. A memory allocation failure due to `http.memcap` being reached leads to a NULL-ptr reference leading to a crash. Upgrade to 7.0.6. | |||||
| CVE-2023-35853 | 1 Oisf | 1 Suricata | 2024-02-28 | N/A | 9.8 CRITICAL |
| In Suricata before 6.0.13, an adversary who controls an external source of Lua rules may be able to execute Lua code. This is addressed in 6.0.13 by disabling Lua unless allow-rules is true in the security lua configuration section. | |||||
| CVE-2023-35852 | 1 Oisf | 1 Suricata | 2024-02-28 | N/A | 7.5 HIGH |
| In Suricata before 6.0.13 (when there is an adversary who controls an external source of rules), a dataset filename, that comes from a rule, may trigger absolute or relative directory traversal, and lead to write access to a local filesystem. This is addressed in 6.0.13 by requiring allow-absolute-filenames and allow-write (in the datasets rules configuration section) if an installation requires traversal/writing in this situation. | |||||
| CVE-2020-19678 | 2 Oisf, Pfsense | 3 Suricata, Pfsense, Suricata Package | 2024-02-28 | 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-2021-37592 | 1 Oisf | 1 Suricata | 2024-02-28 | 7.5 HIGH | 9.8 CRITICAL |
| Suricata before 5.0.8 and 6.x before 6.0.4 allows TCP evasion via a client with a crafted TCP/IP stack that can send a certain sequence of segments. | |||||
| CVE-2021-45098 | 2 Debian, Oisf | 2 Debian Linux, Suricata | 2024-02-28 | 5.0 MEDIUM | 7.5 HIGH |
| An issue was discovered in Suricata before 6.0.4. It is possible to bypass/evade any HTTP-based signature by faking an RST TCP packet with random TCP options of the md5header from the client side. After the three-way handshake, it's possible to inject an RST ACK with a random TCP md5header option. Then, the client can send an HTTP GET request with a forbidden URL. The server will ignore the RST ACK and send the response HTTP packet for the client's request. These packets will not trigger a Suricata reject action. | |||||
| CVE-2021-35063 | 3 Debian, Fedoraproject, Oisf | 3 Debian Linux, Fedora, Suricata | 2024-02-28 | 5.0 MEDIUM | 7.5 HIGH |
| Suricata before 5.0.7 and 6.x before 6.0.3 has a "critical evasion." | |||||
