Any signed-in user can exploit it over the network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2022-42705 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-2022-42705/ (Markdown: https://insights.sbomify.com/CVE-2022-42705/index.md)","id":"CVE-2022-42705","markdown":"https://insights.sbomify.com/CVE-2022-42705/index.md","name":"CVE-2022-42705","record":{"aliases":["ALPINE-CVE-2022-42705","DEBIAN-CVE-2022-42705","GHSA-89gw-96wv-f4r4","UBUNTU-CVE-2022-42705"],"analysis":{"component_type":"server_software","fix_type":"patch","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"Asterisk PBX","requires_auth":"low_privilege","summary":"A remote authenticated attacker can crash the Asterisk PBX server by triggering a use-after-free condition during concurrent subscription activities.","user_interaction":"not_required","vuln_class":"use_after_free"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"asterisk","vendor":"sangoma"},{"product":"certified_asterisk","vendor":"sangoma"}],"cvss":{"score":6.5,"severity":"medium","source":"cisa-adp","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H","version":"3.1"},"cwes":[{"id":"CWE-416","name":"Use After Free"}],"description":"A use-after-free in res_pjsip_pubsub.c in Sangoma Asterisk 16.28, 18.14, 19.6, and certified/18.9-cert2 may allow a remote authenticated attacker to crash Asterisk (denial of service) by performing activity on a subscription via a reliable transport at the same time that Asterisk is also performing activity on that subscription.","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":"Use after free in n/a","id":"CVE-2022-42705","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"use_after_free","year":"2022"},"n_packages":0,"n_references":3,"next":{"headline":"Path traversal in n/a","id":"CVE-2022-42706"},"packages":[],"prev":{"headline":"Cross-site scripting in n/a","id":"CVE-2022-42704"},"products":["n/a"],"published":"2022-12-05","related":[{"cvss_score":9.8,"headline":"Path traversal in n/a","id":"CVE-2024-57520","kev_date_added":null,"published":"2025-02-05"},{"cvss_score":7.7,"headline":"Using malformed From header can forge identity with \";\" or NULL in name portion","id":"CVE-2025-47779","kev_date_added":null,"published":"2025-05-22"},{"cvss_score":7.5,"headline":"Asterisk can crash from a specifically malformed Authorization header in an incoming SIP request","id":"CVE-2025-57767","kev_date_added":null,"published":"2025-08-28"},{"cvss_score":7.5,"headline":"Memory corruption in n/a","id":"CVE-2022-37325","kev_date_added":null,"published":"2022-12-05"},{"cvss_score":7,"headline":"Asterisk Unsafe Shell Sourcing in safe_asterisk Leads to Local Privilege Escalation","id":"CVE-2025-1131","kev_date_added":null,"published":"2025-09-23"},{"cvss_score":6.5,"headline":"Asterisk remotely exploitable leak of RTP UDP ports and internal resources","id":"CVE-2025-54995","kev_date_added":null,"published":"2025-08-28"},{"cvss_score":6.5,"headline":"Asterisk is Vulnerable to Remote DoS and possible RCE Attacks During Memory Allocation","id":"CVE-2025-49832","kev_date_added":null,"published":"2025-08-01"}],"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":"no","exploitation":"none","technical_impact":"partial"},"state":"PUBLISHED","updated":"2025-04-24","vendors":["n/a"]},"summary":"A remote authenticated attacker can crash the Asterisk PBX server by triggering a use-after-free condition during concurrent subscription activities.","url":"https://insights.sbomify.com/CVE-2022-42705/"}
