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-2021-21484 in the wild and no public exploit code.\n\nAffected product: SAP HANA. 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-2021-21484/ (Markdown: https://insights.sbomify.com/CVE-2021-21484/index.md)","id":"CVE-2021-21484","markdown":"https://insights.sbomify.com/CVE-2021-21484/index.md","name":"CVE-2021-21484","record":{"aliases":["GHSA-qq36-2m78-ghvj"],"analysis":{"component_type":"database","fix_type":"configuration_change","impacts":["security_bypass"],"network_reachable":"yes","non_default_config":true,"product_category":"SAP HANA Database","requires_auth":"none","summary":"Attackers can bypass LDAP authentication in SAP HANA if the directory server allows unauthenticated binds, requiring configuration changes to secure the system.","user_interaction":"not_required","vuln_class":"auth_bypass"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"sap","cpe":[{"product":"hana","vendor":"sap"}],"cvss":{"score":7.7,"severity":"high","source":"cna","vector":"CVSS:3.0/AV:N/AC:H/PR:N/UI:N/S:U/C:H/I:H/A:L","version":"3.0"},"cwes":[{"id":"CWE-863","name":"Incorrect Authorization"}],"description":"LDAP authentication in SAP HANA Database version 2.0 can be bypassed if the attached LDAP directory server is configured to enable unauthenticated bind.","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"none_known"},"has_fix":null,"headline":"Auth bypass in SAP HANA","id":"CVE-2021-21484","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"auth_bypass","year":"2021"},"n_packages":0,"n_references":2,"next":{"headline":"Information disclosure in SAP NetWeaver AS for JAVA (Telnet Commands)","id":"CVE-2021-21485"},"packages":[],"prev":{"headline":"Information disclosure in SAP Solution Manager","id":"CVE-2021-21483"},"products":["SAP HANA"],"published":"2021-03-09","related":[{"cvss_score":10,"headline":"Auth bypass in n/a","id":"CVE-2015-7828","kev_date_added":null,"published":"2015-11-10"},{"cvss_score":9.8,"headline":"Code injection in n/a","id":"CVE-2016-6143","kev_date_added":null,"published":"2017-04-13"},{"cvss_score":9.8,"headline":"Weak cryptography in n/a","id":"CVE-2016-6150","kev_date_added":null,"published":"2016-08-05"},{"cvss_score":9.8,"headline":"Memory corruption in n/a","id":"CVE-2016-1928","kev_date_added":null,"published":"2016-01-20"},{"cvss_score":9.3,"headline":"Denial of service in n/a","id":"CVE-2016-1929","kev_date_added":null,"published":"2016-01-20"},{"cvss_score":8.1,"headline":"Auth bypass in n/a","id":"CVE-2016-6144","kev_date_added":null,"published":"2016-08-05"}],"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":"2024-08-03","vendors":["SAP SE"]},"summary":"Attackers can bypass LDAP authentication in SAP HANA if the directory server allows unauthenticated binds, requiring configuration changes to secure the system.","url":"https://insights.sbomify.com/CVE-2021-21484/"}
