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-2021-44108 in the wild and no public exploit code.\n\nAffected product: Open5gs Open5gs. 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-2021-44108/ (Markdown: https://insights.sbomify.com/CVE-2021-44108/index.md)","id":"CVE-2021-44108","markdown":"https://insights.sbomify.com/CVE-2021-44108/index.md","name":"CVE-2021-44108","record":{"aliases":["GHSA-w96w-f34f-w457"],"analysis":{"component_type":"server_software","fix_type":"upgrade","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"5G Core Network","requires_auth":"none","summary":"Remote attackers can cause a denial of service in Open5GS AMF via a crafted SBI request due to a null pointer dereference.","user_interaction":"not_required","vuln_class":"null_dereference"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"open5gs","vendor":"open5gs"}],"cvss":{"score":7.5,"severity":"high","source":"nvd","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":"A null pointer dereference in src/amf/namf-handler.c in Open5GS 2.3.6 and earlier allows remote attackers to Denial of Service via a crafted sbi request to amf.","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"none_known"},"has_fix":false,"headline":"Null dereference in n/a","id":"CVE-2021-44108","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":"open5gs:open5gs","products":["open5gs:open5gs"],"type":"null_dereference","year":"2021"},"n_packages":0,"n_references":2,"next":{"headline":"Memory corruption in n/a","id":"CVE-2021-44109"},"packages":[],"prev":{"headline":"SQL injection in n/a","id":"CVE-2021-44098"},"products":["n/a"],"published":"2022-04-05","related":[{"cvss_score":9.8,"headline":"Memory corruption in n/a","id":"CVE-2024-40130","kev_date_added":null,"published":"2024-07-16"},{"cvss_score":9.8,"headline":"Missing authorization in n/a","id":"CVE-2021-28122","kev_date_added":null,"published":"2021-03-10"},{"cvss_score":8.8,"headline":"Hardcoded credentials in n/a","id":"CVE-2021-25863","kev_date_added":null,"published":"2021-01-26"},{"cvss_score":8.7,"headline":"Reachable Assertion vulnerability in Open5GS","id":"CVE-2025-41067","kev_date_added":null,"published":"2025-10-27"},{"cvss_score":8.7,"headline":"Reachable Assertion vulnerability in Open5GS","id":"CVE-2025-41068","kev_date_added":null,"published":"2025-10-27"},{"cvss_score":8.6,"headline":"Denial of service in n/a","id":"CVE-2023-37015","kev_date_added":null,"published":"2025-01-22"},{"cvss_score":8.6,"headline":"Denial of service in n/a","id":"CVE-2023-37016","kev_date_added":null,"published":"2025-01-22"}],"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":"2024-08-04","vendors":["n/a"]},"summary":"Remote attackers can cause a denial of service in Open5GS AMF via a crafted SBI request due to a null pointer dereference.","url":"https://insights.sbomify.com/CVE-2021-44108/"}
