In Suricata before 6.0.13, an adversary who controls an external source of Lua rules may be able to execute Lua code

CVE-2023-35853 9.8 - Critical - June 19, 2023

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.

In Suricata before 6.0.13 (when there is an adversary who controls an external source of rules), a dataset filename

CVE-2023-35852 7.5 - High - June 19, 2023

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.

Directory traversal

Directory Traversal vulnerability found in Pfsense v.2.1.3 and Pfsense Suricata v.1.4.6 pkg v.1.0.1

CVE-2020-19678 7.5 - High - April 06, 2023

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.

Directory traversal

An issue was discovered in Suricata before 6.0.4

CVE-2021-45098 7.5 - High - December 16, 2021

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.

Suricata before 5.0.8 and 6.x before 6.0.4 allows TCP evasion via a client with a crafted TCP/IP stack

CVE-2021-37592 9.8 - Critical - November 19, 2021

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.

Memory Corruption

Suricata before 5.0.7 and 6.x before 6.0.3 has a "critical evasion

CVE-2021-35063 7.5 - High - July 22, 2021

Suricata before 5.0.7 and 6.x before 6.0.3 has a "critical evasion."

In OISF LibHTP before 0.5.31

CVE-2019-17420 5.3 - Medium - October 10, 2019

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.

Improper Input Validation

Open Information Security Foundation Suricata prior to version 4.1.3 is affected by: Denial of Service - TCP/HTTP detection bypass

CVE-2019-1010279 7.5 - High - July 18, 2019

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.

Improper Verification of Cryptographic Signature

Open Information Security Foundation Suricata prior to version 4.1.2 is affected by: Denial of Service - DNS detection bypass

CVE-2019-1010251 7.5 - High - July 18, 2019

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.

Improper Input Validation

A buffer over-read issue was discovered in Suricata 4.1.x before 4.1.4

CVE-2019-10050 7.5 - High - May 13, 2019

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.

Out-of-bounds Read

CVE-2018-10243 9.8 - Critical - April 04, 2019

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.

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

CVE-2018-1000167 7.8 - High - April 18, 2018

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.
