Any signed-in user can exploit it over the network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2011-4063 in the wild and no public exploit code.\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-2011-4063/ (Markdown: https://insights.sbomify.com/CVE-2011-4063/index.md)","id":"CVE-2011-4063","markdown":"https://insights.sbomify.com/CVE-2011-4063/index.md","name":"CVE-2011-4063","record":{"aliases":["DEBIAN-CVE-2011-4063","GHSA-wxfw-gh9x-v224"],"analysis":{"component_type":"server_software","fix_type":"upgrade","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"Asterisk PBX","requires_auth":"low_privilege","summary":"Remote authenticated users can crash the Asterisk SIP daemon via malformed requests due to improper variable initialization.","user_interaction":"not_required","vuln_class":"denial_of_service"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"open_source","vendor":"asterisk"}],"cvss":{"score":6.8,"severity":"medium","source":"nvd","vector":"AV:N/AC:L/Au:S/C:N/I:N/A:C","version":"2.0"},"cwes":[{"id":"CWE-20","name":"Improper Input Validation"}],"description":"chan_sip.c in the SIP channel driver in Asterisk Open Source 1.8.x before 1.8.7.1 and 10.x before 10.0.0-rc1 does not properly initialize variables during request parsing, which allows remote authenticated users to cause a denial of service (daemon crash) via a malformed request.","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"none_known"},"has_fix":true,"headline":"Denial of service in n/a","id":"CVE-2011-4063","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"denial_of_service","year":"2011"},"n_packages":0,"n_references":7,"next":{"headline":"Cross-site scripting in n/a","id":"CVE-2011-4064"},"packages":[],"prev":{"headline":"Memory corruption in n/a","id":"CVE-2011-4062"},"products":["n/a"],"published":"2011-10-21","related":[{"cvss_score":7.5,"headline":"Memory corruption in n/a","id":"CVE-2013-2685","kev_date_added":null,"published":"2013-03-29"},{"cvss_score":6.5,"headline":"Missing authorization in n/a","id":"CVE-2012-2414","kev_date_added":null,"published":"2012-04-30"},{"cvss_score":6.5,"headline":"Memory corruption in n/a","id":"CVE-2012-2415","kev_date_added":null,"published":"2012-04-30"},{"cvss_score":6.5,"headline":"Denial of service in n/a","id":"CVE-2012-2416","kev_date_added":null,"published":"2012-04-30"},{"cvss_score":5.8,"headline":"Other in n/a","id":"CVE-2008-1333","kev_date_added":null,"published":"2008-03-20"},{"cvss_score":4.3,"headline":"Null dereference in n/a","id":"CVE-2012-0885","kev_date_added":null,"published":"2012-01-25"}],"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":"2024-08-06","vendors":["n/a"]},"summary":"Remote authenticated users can crash the Asterisk SIP daemon via malformed requests due to improper variable initialization.","url":"https://insights.sbomify.com/CVE-2011-4063/"}
