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-2022-39063 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-2022-39063/ (Markdown: https://insights.sbomify.com/CVE-2022-39063/index.md)","id":"CVE-2022-39063","markdown":"https://insights.sbomify.com/CVE-2022-39063/index.md","name":"CVE-2022-39063","record":{"aliases":["GHSA-963g-g6x3-46cf"],"analysis":{"component_type":"server_software","fix_type":"patch","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"5G Core Network","requires_auth":"none","summary":"A remote attacker can cause a segmentation fault and denial of service in Open5GS UPF by sending a crafted PFCP Session Establishment Request with an oversized length field.","user_interaction":"not_required","vuln_class":"memory_corruption"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"SNPS","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-676","name":"Use of Potentially Dangerous Function"}],"description":"When Open5GS UPF receives a PFCP Session Establishment Request, it stores related values for building the PFCP Session Establishment Response. Once UPF receives a request, it gets the f_teid_len from incoming message, and then uses it to copy data from incoming message to struct f_teid without checking the maximum length. If the pdi.local_f_teid.len exceeds the maximum length of the struct of f_teid, the memcpy() overwrites the fields (e.g., f_teid_len) after f_teid in the pdr struct. After parsing the request, the UPF starts to build a response. The f_teid_len with its overwritten value is used as a length for memcpy(). A segmentation fault occurs, as a result of a memcpy(), if this overwritten value is large enough.","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":"Memory corruption in Open5GS","id":"CVE-2022-39063","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":"open5gs:open5gs","products":["open5gs:open5gs"],"type":"memory_corruption","year":"2022"},"n_packages":0,"n_references":1,"next":{"headline":"Denial of service in TRÅDFRI smart lighting system","id":"CVE-2022-39064"},"packages":[],"prev":{"headline":"Privilege escalation in SICAM TOOLBOX II","id":"CVE-2022-39062"},"products":["Open5GS"],"published":"2022-09-16","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":"2024-08-03","vendors":["Open5GS"]},"summary":"A remote attacker can cause a segmentation fault and denial of service in Open5GS UPF by sending a crafted PFCP Session Establishment Request with an oversized length field.","url":"https://insights.sbomify.com/CVE-2022-39063/"}
