Any signed-in user can exploit it over the network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2012-4737 in the wild and no public exploit code.\n\nAffected product: Digium Asterisk. 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-2012-4737/ (Markdown: https://insights.sbomify.com/CVE-2012-4737/index.md)","id":"CVE-2012-4737","markdown":"https://insights.sbomify.com/CVE-2012-4737/index.md","name":"CVE-2012-4737","record":{"aliases":["DEBIAN-CVE-2012-4737","GHSA-5hf4-mrr5-f9rh"],"analysis":{"component_type":"server_software","fix_type":"upgrade","impacts":["security_bypass"],"network_reachable":"yes","non_default_config":false,"product_category":"Asterisk PBX","requires_auth":"low_privilege","summary":"Remote authenticated users can bypass outbound-call restrictions in Asterisk by leveraging peer credentials due to missing ACL enforcement.","user_interaction":"not_required","vuln_class":"auth_bypass"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"asterisk","vendor":"digium"},{"product":"certified_asterisk","vendor":"digium"}],"cvss":{"score":6,"severity":"medium","source":"nvd","vector":"AV:N/AC:M/Au:S/C:P/I:P/A:P","version":"2.0"},"cwes":[{"id":"CWE-264","name":null}],"description":"channels/chan_iax2.c in Asterisk Open Source 1.8.x before 1.8.15.1 and 10.x before 10.7.1, Certified Asterisk 1.8.11 before 1.8.11-cert7, Asterisk Digiumphones 10.x.x-digiumphones before 10.7.1-digiumphones, and Asterisk Business Edition C.3.x before C.3.7.6 does not enforce ACL rules during certain uses of peer credentials, which allows remote authenticated users to bypass intended outbound-call restrictions by leveraging the availability of these credentials.","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":"Auth bypass in n/a","id":"CVE-2012-4737","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":"digium:asterisk","products":["digium:asterisk","digium:certified_asterisk"],"type":"auth_bypass","year":"2012"},"n_packages":0,"n_references":6,"next":{"headline":"Cross-site scripting in n/a","id":"CVE-2012-4739"},"packages":[],"prev":{"headline":"Security feature bypass in n/a","id":"CVE-2012-4736"},"products":["n/a"],"published":"2012-08-31","related":[{"cvss_score":9.8,"headline":"Command injection in n/a","id":"CVE-2017-14100","kev_date_added":null,"published":"2017-09-02"},{"cvss_score":9,"headline":"Privilege escalation in n/a","id":"CVE-2014-8418","kev_date_added":null,"published":"2014-11-24"},{"cvss_score":9,"headline":"Missing authorization in n/a","id":"CVE-2011-1599","kev_date_added":null,"published":"2011-04-27"},{"cvss_score":8.8,"headline":"Memory corruption in n/a","id":"CVE-2017-16671","kev_date_added":null,"published":"2017-11-09"},{"cvss_score":8.8,"headline":"Memory corruption in n/a","id":"CVE-2017-7617","kev_date_added":null,"published":"2017-04-10"},{"cvss_score":7.8,"headline":"Denial of service in n/a","id":"CVE-2009-2726","kev_date_added":null,"published":"2009-08-12"},{"cvss_score":7.8,"headline":"Null dereference in n/a","id":"CVE-2007-1306","kev_date_added":null,"published":"2007-03-07"}],"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 bypass outbound-call restrictions in Asterisk by leveraging peer credentials due to missing ACL enforcement.","url":"https://insights.sbomify.com/CVE-2012-4737/"}
