An attacker can exploit it over the internet without logging in, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2019-25043 in the wild and no public exploit code.\n\nAffected product: n/a. 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-2019-25043/ (Markdown: https://insights.sbomify.com/CVE-2019-25043/index.md)","id":"CVE-2019-25043","markdown":"https://insights.sbomify.com/CVE-2019-25043/index.md","name":"CVE-2019-25043","record":{"aliases":["DEBIAN-CVE-2019-25043","GHSA-p89w-8r2h-7mjp","UBUNTU-CVE-2019-25043"],"analysis":{"component_type":"server_software","fix_type":"upgrade","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"Web Application Firewall","requires_auth":"none","summary":"A malformed Cookie header causes a worker-process crash in ModSecurity, leading to denial of service for web servers using this WAF.","user_interaction":"not_required","vuln_class":"denial_of_service"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"modsecurity","vendor":"owasp"}],"cvss":{"score":5.3,"severity":"medium","source":"nvd","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:L","version":"3.1"},"cwes":[{"id":"CWE-755","name":"Improper Handling of Exceptional Conditions"}],"description":"ModSecurity 3.x before 3.0.4 mishandles key-value pair parsing, as demonstrated by a \"string index out of range\" error and worker-process crash for a \"Cookie: =abc\" header.","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"none_known"},"has_fix":true,"headline":"Denial of service in n/a","id":"CVE-2019-25043","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"denial_of_service","year":"2019"},"n_packages":0,"n_references":1,"next":{"headline":"Use after free in n/a","id":"CVE-2019-25044"},"packages":[],"prev":{"headline":"Memory corruption in n/a","id":"CVE-2019-25042"},"products":["n/a"],"published":"2021-05-06","related":[{"cvss_score":8.6,"headline":"Security feature bypass in ModSecurity","id":"CVE-2026-52747","kev_date_added":null,"published":"2026-07-10"},{"cvss_score":8.6,"headline":"WAF bypass of the ModSecurity v3 release line","id":"CVE-2024-1019","kev_date_added":null,"published":"2024-01-30"},{"cvss_score":8.2,"headline":"ModSecurity: Unsigned integer underflow in @verifySSN / @verifyCPF / @verifySVNR operators","id":"CVE-2026-42268","kev_date_added":null,"published":"2026-05-12"},{"cvss_score":8.2,"headline":"libModSecurity3 denial of service via segfault when using t:hexDecode on single-character query strings","id":"CVE-2026-30923","kev_date_added":null,"published":"2026-05-05"},{"cvss_score":7.5,"headline":"ModSecurity has possible DoS vulnerability in sanitiseArg action","id":"CVE-2025-48866","kev_date_added":null,"published":"2025-06-02"},{"cvss_score":7.5,"headline":"Trustwave ModSecurity 3.x before 3.0.10 has Inefficient Algorithmic Complexity.","id":"CVE-2023-38285","kev_date_added":null,"published":"2023-07-26"},{"cvss_score":7.5,"headline":"Denial of service in n/a","id":"CVE-2023-28882","kev_date_added":null,"published":"2023-04-28"}],"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":null,"exploitation":null,"technical_impact":null},"state":"PUBLISHED","updated":"2024-08-05","vendors":["n/a"]},"summary":"A malformed Cookie header causes a worker-process crash in ModSecurity, leading to denial of service for web servers using this WAF.","url":"https://insights.sbomify.com/CVE-2019-25043/"}
