CVE-2019-10050 1 Oisf 1 Suricata 2024-11-21 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 2024-11-21 N/A
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 2024-11-21 N/A
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 2024-11-21 N/A
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 2024-11-21 N/A
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 2024-11-21 N/A
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 2024-11-21 N/A
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 2024-11-21 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 2024-11-21 N/A
Suricata before 1.4.6 allows remote attackers to cause a denial of service (crash) via a malformed SSL record.
CVE-2024-47522 1 Oisf 1 Suricata 2024-10-22 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 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 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 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 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-2024-45797 1 Oisf 1 Libhtp 2024-10-18 7.5 High
LibHTP is a security-aware parser for the HTTP protocol and the related bits and pieces. Prior to version 0.5.49, unbounded processing of HTTP request and response headers can lead to excessive CPU time and memory utilization, possibly leading to extreme slowdowns. This issue is addressed in 0.5.49.
