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-2021-30641 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- apache (Bitnami): affected from 2.4.39; fixed in 2.4.47\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-2021-30641/ (Markdown: https://insights.sbomify.com/CVE-2021-30641/index.md)","id":"CVE-2021-30641","markdown":"https://insights.sbomify.com/CVE-2021-30641/index.md","name":"CVE-2021-30641","record":{"aliases":["ALPINE-CVE-2021-30641","AZL-6478","BIT-apache-2021-30641","CLEANSTART-2026-MG62687","DEBIAN-CVE-2021-30641","GHSA-jfgv-4796-2jw7","UBUNTU-CVE-2021-30641"],"analysis":{"component_type":"server_software","fix_type":"upgrade","impacts":["security_bypass"],"network_reachable":"yes","non_default_config":true,"product_category":"Apache HTTP Server","requires_auth":"none","summary":"Attackers can bypass security controls by exploiting unexpected URL matching behavior when MergeSlashes is disabled in Apache HTTP Server.","user_interaction":"not_required","vuln_class":"security_feature_bypass"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"apache","cpe":[{"product":"http_server","vendor":"apache"},{"product":"debian_linux","vendor":"debian"},{"product":"fedora","vendor":"fedoraproject"},{"product":"enterprise_manager_ops_center","vendor":"oracle"},{"product":"instantis_enterprisetrack","vendor":"oracle"},{"product":"zfs_storage_appliance_kit","vendor":"oracle"}],"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:L/A:N","version":"3.1"},"cwes":[],"description":"Apache HTTP Server versions 2.4.39 to 2.4.46 Unexpected matching behavior with 'MergeSlashes OFF'","ecosystems":["Bitnami"],"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":"Unexpected URL matching with 'MergeSlashes OFF'","id":"CVE-2021-30641","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":"Bitnami","product":"apache:http_server","products":["apache:http_server","debian:debian_linux","fedoraproject:fedora","oracle:enterprise_manager_ops_center","oracle:instantis_enterprisetrack","oracle:zfs_storage_appliance_kit"],"type":"security_feature_bypass","year":"2021"},"n_packages":1,"n_references":12,"next":{"headline":"Command injection in Symantec Security Analytics","id":"CVE-2021-30642"},"packages":[{"ecosystem":"Bitnami","fixed":["2.4.47"],"introduced":["2.4.39"],"last_affected":[],"package":"apache","purl":"pkg:bitnami/apache","source":"BIT-apache-2021-30641"}],"prev":{"headline":"Auth weakness in JNDIRealm","id":"CVE-2021-30640"},"products":["Apache HTTP Server"],"published":"2021-06-10","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":"Apache-2.0","name":"Bitnami","prefix":"BIT"},{"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":"FIRST CVSS licence","name":"CVSS (FIRST)"}],"ssvc":{"automatable":null,"exploitation":null,"technical_impact":null},"state":"PUBLISHED","updated":"2024-08-03","vendors":["Apache Software Foundation"]},"summary":"Attackers can bypass security controls by exploiting unexpected URL matching behavior when MergeSlashes is disabled in Apache HTTP Server.","url":"https://insights.sbomify.com/CVE-2021-30641/"}
