An attacker can exploit it over the internet without logging in, with no action from the victim.\nExploitation: It is not confirmed as exploited in the wild, but public exploit code for CVE-2026-45747 exists.\n\nAffected product: Oisf Suricata. No package-level version data is available, so check the vendor advisory linked from the reference page.\n\nTask:\n1. Search the dependency manifests and lockfiles (for example package.json, package-lock.json, requirements.txt, poetry.lock, uv.lock, pom.xml, build.gradle, go.mod, Cargo.lock, Gemfile.lock) and any Dockerfiles for the affected packages, including transitive dependencies.\n2. If an affected version is in use, upgrade it to the fixed version for its release line with the project's package manager, so the lockfile is regenerated. Prefer the smallest upgrade that fixes it.\n3. If there is no fix, or the upgrade would break the build, do not guess: explain the risk and the safest workaround instead.\n4. Run the tests and summarise what changed and why.\n5. If nothing in the project is affected, say so and change nothing.\n\nReference: https://insights.sbomify.com/CVE-2026-45747/ (Markdown: https://insights.sbomify.com/CVE-2026-45747/index.md)","id":"CVE-2026-45747","markdown":"https://insights.sbomify.com/CVE-2026-45747/index.md","name":"CVE-2026-45747","record":{"aliases":["DEBIAN-CVE-2026-45747","GHSA-vfc5-9844-rmhv","UBUNTU-CVE-2026-45747"],"analysis":{"component_type":"server_software","fix_type":"upgrade","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":true,"product_category":"Network IDS/IPS engine","requires_auth":"none","summary":"Attackers can crash Suricata by sending crafted TLS traffic if Lua scripts request certificate info, requiring an upgrade or script modification.","user_interaction":"not_required","vuln_class":"null_dereference"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"GitHub_M","cpe":[{"product":"suricata","vendor":"oisf"}],"cvss":{"score":7.5,"severity":"high","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H","version":"3.1"},"cwes":[{"id":"CWE-476","name":"NULL Pointer Dereference"}],"description":"Suricata is a network Intrusion Detection System, Intrusion Prevention System and Network Security Monitoring engine. Prior to version 7.0.16, the Lua TLS certificate information helper could dereference NULL certificate fields when a Lua script requested certificate information for TLS traffic where some certificate fields were absent. Crafted TLS traffic processed by a deployment using affected Lua TLS scripting could crash Suricata, resulting in denial of service. Version 7.0.16 contains a fix. As a workaround, avoid Lua scripts that call TLS certificate information helpers on untrusted traffic (`TlsGetCertInfo` function), or update scripts to handle missing certificate fields where possible.","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"weaponised"},"has_fix":true,"headline":"Suricata lua/tls: null dereference in TlsGetCertInfo","id":"CVE-2026-45747","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":"oisf:suricata","products":["oisf:suricata"],"type":"null_dereference","year":"2026"},"n_packages":0,"n_references":3,"next":{"headline":"Termix Vulnerable to Remote Code Execution via SSH Tunnel Forward Command Injection","id":"CVE-2026-45748"},"packages":[],"prev":{"headline":"Termix Vulnerable to Arbitrary Command Execution via Session Hijacking","id":"CVE-2026-45746"},"products":["suricata"],"published":"2026-09-10","related":[{"cvss_score":9.8,"headline":"Code injection in n/a","id":"CVE-2023-35853","kev_date_added":null,"published":"2023-06-19"},{"cvss_score":9.8,"headline":"Other in n/a","id":"CVE-2021-37592","kev_date_added":null,"published":"2021-11-19"},{"cvss_score":9.8,"headline":"Integer overflow in n/a","id":"CVE-2018-10244","kev_date_added":null,"published":"2019-04-04"},{"cvss_score":9.4,"headline":"Memory corruption in Suricata","id":"CVE-2026-94083","kev_date_added":null,"published":"2026-09-20"},{"cvss_score":9.4,"headline":"Use after free in Suricata","id":"CVE-2026-94084","kev_date_added":null,"published":"2026-09-20"},{"cvss_score":9.1,"headline":"Suricata http2: protocol-change type confusion can lead to denial of service","id":"CVE-2026-45764","kev_date_added":null,"published":"2026-09-10"},{"cvss_score":8.2,"headline":"Suricata smtp/mime: heap out-of-bounds read quoted-printable decoder","id":"CVE-2026-57228","kev_date_added":null,"published":"2026-09-18"}],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"class":"attribution","licence":"US public information, NVD API terms","name":"NVD"},{"class":"attribution","licence":"CWE Terms of Use","name":"CWE (MITRE)"},{"class":"attribution","licence":"FIRST CVSS licence","name":"CVSS (FIRST)"}],"ssvc":{"automatable":"yes","exploitation":"poc","technical_impact":"partial"},"state":"PUBLISHED","updated":"2026-09-10","vendors":["OISF"]},"summary":"Attackers can crash Suricata by sending crafted TLS traffic if Lua scripts request certificate info, requiring an upgrade or script modification.","url":"https://insights.sbomify.com/CVE-2026-45747/"}
