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-2016-2161 in the wild and no public exploit code.\n\nAffected product: Apache Http Server. 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-2016-2161/ (Markdown: https://insights.sbomify.com/CVE-2016-2161/index.md)","id":"CVE-2016-2161","markdown":"https://insights.sbomify.com/CVE-2016-2161/index.md","name":"CVE-2016-2161","record":{"aliases":["DEBIAN-CVE-2016-2161","GHSA-3v6f-955w-932h","UBUNTU-CVE-2016-2161"],"analysis":{"component_type":"server_software","fix_type":"upgrade","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"Apache HTTP Server","requires_auth":"none","summary":"Malicious input to mod_auth_digest causes Apache HTTP Server to crash persistently, leading to denial of service.","user_interaction":"not_required","vuln_class":"denial_of_service"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"apache","cpe":[{"product":"http_server","vendor":"apache"}],"cvss":{"score":7.5,"severity":"high","source":"nvd","vector":"CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H","version":"3.0"},"cwes":[{"id":"CWE-20","name":"Improper Input Validation"},{"id":"CWE-823","name":"Use of Out-of-range Pointer Offset"}],"description":"In Apache HTTP Server versions 2.4.0 to 2.4.23, malicious input to mod_auth_digest can cause the server to crash, and each instance continues to crash even for subsequently valid requests.","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 Apache HTTP Server","id":"CVE-2016-2161","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":"apache:http_server","products":["apache:http_server"],"type":"denial_of_service","year":"2016"},"n_packages":0,"n_references":27,"next":{"headline":"Apache Struts XSS Vulnerability","id":"CVE-2016-2162"},"packages":[],"prev":{"headline":"Privilege escalation in n/a","id":"CVE-2016-2160"},"products":["Apache HTTP Server"],"published":"2017-07-27","related":[{"cvss_score":9.8,"headline":"Apache HTTP Server Path Traversal","id":"CVE-2021-42013","kev_date_added":"2021-11-03","published":"2021-10-07"},{"cvss_score":9.1,"headline":"Apache HTTP Server Improper Escaping of Output","id":"CVE-2024-38475","kev_date_added":"2025-05-01","published":"2024-07-01"},{"cvss_score":9,"headline":"Apache HTTP Server-Side Request Forgery (SSRF)","id":"CVE-2021-40438","kev_date_added":"2021-12-01","published":"2021-09-16"},{"cvss_score":7.8,"headline":"Apache HTTP Server Privilege Escalation","id":"CVE-2019-0211","kev_date_added":"2021-11-03","published":"2019-04-08"},{"cvss_score":7.5,"headline":"Apache HTTP Server Path Traversal","id":"CVE-2021-41773","kev_date_added":"2021-11-03","published":"2021-10-05"},{"cvss_score":10,"headline":"Use after free in n/a","id":"CVE-2010-0425","kev_date_added":null,"published":"2010-03-05"},{"cvss_score":10,"headline":"Auth bypass in n/a","id":"CVE-2005-2700","kev_date_added":null,"published":"2005-09-06"}],"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":"2024-09-16","vendors":["Apache Software Foundation"]},"summary":"Malicious input to mod_auth_digest causes Apache HTTP Server to crash persistently, leading to denial of service.","url":"https://insights.sbomify.com/CVE-2016-2161/"}
