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.","state":"PUBLIC","assigner":"cve@mitre.org","published_at":"2021-12-16 05:15:00","updated_at":"2022-01-04 16:48:00"},"problem_types":["NVD-CWE-noinfo"],"metrics":[],"references":[{"url":"https://github.com/OISF/suricata/releases","name":"https://github.com/OISF/suricata/releases","refsource":"MISC","tags":[],"title":"Releases · OISF/suricata · GitHub","mime":"text/html","httpstatus":"200","archivestatus":"200"},{"url":"https://forum.suricata.io/t/suricata-6-0-4-and-5-0-8-released/1942","name":"https://forum.suricata.io/t/suricata-6-0-4-and-5-0-8-released/1942","refsource":"MISC","tags":[],"title":"Suricata 6.0.4 and 5.0.8 released - Announcements - Suricata","mime":"text/html","httpstatus":"200","archivestatus":"200"},{"url":"https://github.com/OISF/suricata/commit/50e2b973eeec7172991bf8f544ab06fb782b97df","name":"https://github.com/OISF/suricata/commit/50e2b973eeec7172991bf8f544ab06fb782b97df","refsource":"MISC","tags":[],"title":"stream/tcp: handle RST with MD5 or AO header · OISF/suricata@50e2b97 · GitHub","mime":"text/html","httpstatus":"200","archivestatus":"404"},{"url":"https://redmine.openinfosecfoundation.org/issues/4710","name":"https://redmine.openinfosecfoundation.org/issues/4710","refsource":"MISC","tags":[],"title":"Security #4710: tcp: Bypass of Payload Detection on TCP RST with options of MD5header - Suricata - Open Information Security Foundation","mime":"text/html","httpstatus":"200","archivestatus":"404"},{"url":"https://www.cve.org/CVERecord?id=CVE-2021-45098","name":"CVE Program record","refsource":"CVE.ORG","tags":["canonical"]},{"url":"https://nvd.nist.gov/vuln/detail/CVE-2021-45098","name":"NVD vulnerability detail","refsource":"NVD","tags":["canonical","analysis"]}],"affected":[],"timeline":[],"solutions":[],"workarounds":[],"exploits":[],"credits":[],"nvd_cpes":[{"cve_year":"2021","cve_id":"45098","vulnerable":"1","versionEndIncluding":"","cpe1":"cpe","cpe2":"2.3","cpe3":"o","cpe4":"debian","cpe5":"debian_linux","cpe6":"10.0","cpe7":"*","cpe8":"*","cpe9":"*","cpe10":"*","cpe11":"*","cpe12":"*","cpe13":"*"},{"cve_year":"2021","cve_id":"45098","vulnerable":"1","versionEndIncluding":"","cpe1":"cpe","cpe2":"2.3","cpe3":"o","cpe4":"debian","cpe5":"debian_linux","cpe6":"11.0","cpe7":"*","cpe8":"*","cpe9":"*","cpe10":"*","cpe11":"*","cpe12":"*","cpe13":"*"},{"cve_year":"2021","cve_id":"45098","vulnerable":"1","versionEndIncluding":"","cpe1":"cpe","cpe2":"2.3","cpe3":"o","cpe4":"debian","cpe5":"debian_linux","cpe6":"9.0","cpe7":"*","cpe8":"*","cpe9":"*","cpe10":"*","cpe11":"*","cpe12":"*","cpe13":"*"},{"cve_year":"2021","cve_id":"45098","vulnerable":"1","versionEndIncluding":"","cpe1":"cpe","cpe2":"2.3","cpe3":"a","cpe4":"oisf","cpe5":"suricata","cpe6":"*","cpe7":"*","cpe8":"*","cpe9":"*","cpe10":"*","cpe11":"*","cpe12":"*","cpe13":"*"}],"vendor_comments":[],"enrichments":{"kev":null,"epss":null,"legacy_qids":[{"cve":"CVE-2021-45098","qid":"182402","title":"Debian Security Update for suricata (CVE-2021-45098)"},{"cve":"CVE-2021-45098","qid":"502188","title":"Alpine Linux Security Update for suricata"},{"cve":"CVE-2021-45098","qid":"505423","title":"Alpine Linux Security Update for suricata"}]},"source_records":{"cve_program":{"CVE_data_meta":{"ASSIGNER":"cve@mitre.org","ID":"CVE-2021-45098","STATE":"PUBLIC"},"affects":{"vendor":{"vendor_data":[{"product":{"product_data":[{"product_name":"n/a","version":{"version_data":[{"version_value":"n/a"}]}}]},"vendor_name":"n/a"}]}},"data_format":"MITRE","data_type":"CVE","data_version":"4.0","description":{"description_data":[{"lang":"eng","value":"An issue was discovered in Suricata before 6.0.4.
