An attacker can exploit it over the internet without logging in, with no action from the victim.\nExploitation: It is not confirmed as exploited in the wild, but public exploit code for CVE-2020-27507 exists.\n\nAffected product: n/a. 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-2020-27507/ (Markdown: https://insights.sbomify.com/CVE-2020-27507/index.md)","id":"CVE-2020-27507","markdown":"https://insights.sbomify.com/CVE-2020-27507/index.md","name":"CVE-2020-27507","record":{"aliases":["DEBIAN-CVE-2020-27507","DLA-3438-1","GHSA-q52j-c5xj-88qf","UBUNTU-CVE-2020-27507"],"analysis":{"component_type":"server_software","fix_type":"upgrade","impacts":["denial_of_service","code_execution"],"network_reachable":"yes","non_default_config":false,"product_category":"Kamailio SIP server","requires_auth":"none","summary":"A buffer overflow in Kamailio SIP server allows remote attackers to crash the service or potentially execute arbitrary code via crafted INVITE requests.","user_interaction":"not_required","vuln_class":"memory_corruption"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"kamailio","vendor":"kamailio"}],"cvss":{"score":9.8,"severity":"critical","source":"cisa-adp","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-120","name":"Buffer Copy without Checking Size of Input"}],"description":"The Kamailio SIP before 5.5.0 server mishandles INVITE requests with duplicated fields and overlength tag, leading to a buffer overflow that crashes the server or possibly have unspecified other impact.","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"weaponised"},"has_fix":true,"headline":"Memory corruption in n/a","id":"CVE-2020-27507","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"memory_corruption","year":"2020"},"n_packages":0,"n_references":3,"next":{"headline":"Information disclosure in n/a","id":"CVE-2020-27508"},"packages":[],"prev":{"headline":"Auth bypass in n/a","id":"CVE-2020-27488"},"products":["n/a"],"published":"2023-03-15","related":[{"cvss_score":9.8,"headline":"File upload in n/a","id":"CVE-2013-7426","kev_date_added":null,"published":"2017-08-29"},{"cvss_score":7.8,"headline":"Path traversal in n/a","id":"CVE-2015-1590","kev_date_added":null,"published":"2017-09-07"},{"cvss_score":7.8,"headline":"Privilege escalation in n/a","id":"CVE-2015-1591","kev_date_added":null,"published":"2017-06-27"},{"cvss_score":7.5,"headline":"Denial of service in n/a","id":"CVE-2026-52022","kev_date_added":null,"published":"2026-09-01"},{"cvss_score":7.5,"headline":"Denial of service in n/a","id":"CVE-2026-52023","kev_date_added":null,"published":"2026-09-01"},{"cvss_score":7.5,"headline":"Kamailio Core: TCP Data Processing Vulnerability","id":"CVE-2026-39863","kev_date_added":null,"published":"2026-04-08"}],"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":"poc","technical_impact":"total"},"state":"PUBLISHED","updated":"2025-02-27","vendors":["n/a"]},"summary":"A buffer overflow in Kamailio SIP server allows remote attackers to crash the service or potentially execute arbitrary code via crafted INVITE requests.","url":"https://insights.sbomify.com/CVE-2020-27507/"}
