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-2024-34476 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-2024-34476/ (Markdown: https://insights.sbomify.com/CVE-2024-34476/index.md)","id":"CVE-2024-34476","markdown":"https://insights.sbomify.com/CVE-2024-34476/index.md","name":"CVE-2024-34476","record":{"aliases":["GHSA-w664-jc4g-5pm6"],"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":"A reachable assertion in Open5GS allows a remote user to crash the AMF service by sending crafted NAS messages.","user_interaction":"not_required","vuln_class":"denial_of_service"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"open5gs","vendor":"open5gs"}],"cvss":{"score":5.3,"severity":"medium","source":"cisa-adp","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-805","name":"Buffer Access with Incorrect Length Value"}],"description":"Open5GS before 2.7.1 is vulnerable to a reachable assertion that can cause an AMF crash via NAS messages from a UE: ogs_nas_encrypt in lib/nas/common/security.c for pkbuf-\u003elen.","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":"Denial of service in n/a","id":"CVE-2024-34476","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":"open5gs:open5gs","products":["open5gs:open5gs"],"type":"denial_of_service","year":"2024"},"n_packages":0,"n_references":2,"next":{"headline":"Privilege escalation in n/a","id":"CVE-2024-34477"},"packages":[],"prev":{"headline":"Denial of service in n/a","id":"CVE-2024-34475"},"products":["n/a"],"published":"2024-05-04","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":"yes","exploitation":"none","technical_impact":"partial"},"state":"PUBLISHED","updated":"2024-08-02","vendors":["n/a"]},"summary":"A reachable assertion in Open5GS allows a remote user to crash the AMF service by sending crafted NAS messages.","url":"https://insights.sbomify.com/CVE-2024-34476/"}
