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-2011-4598 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-2011-4598/ (Markdown: https://insights.sbomify.com/CVE-2011-4598/index.md)","id":"CVE-2011-4598","markdown":"https://insights.sbomify.com/CVE-2011-4598/index.md","name":"CVE-2011-4598","record":{"aliases":["DEBIAN-CVE-2011-4598","GHSA-w869-x8wp-7hr5"],"analysis":{"component_type":"server_software","fix_type":"upgrade","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":true,"product_category":"Asterisk PBX","requires_auth":"none","summary":"Remote attackers can crash the Asterisk daemon via crafted SIP requests when automon is enabled, causing denial of service.","user_interaction":"not_required","vuln_class":"null_dereference"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"redhat","cpe":[{"product":"asterisk","vendor":"digium"}],"cvss":{"score":4.3,"severity":"medium","source":"nvd","vector":"AV:N/AC:M/Au:N/C:N/I:N/A:P","version":"2.0"},"cwes":[{"id":"CWE-200","name":"Exposure of Sensitive Information to an Unauthorized Actor"}],"description":"The handle_request_info function in channels/chan_sip.c in Asterisk Open Source 1.6.2.x before 1.6.2.21 and 1.8.x before 1.8.7.2, when automon is enabled, allows remote attackers to cause a denial of service (NULL pointer dereference and daemon crash) via a crafted sequence of SIP requests.","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":"Null dereference in n/a","id":"CVE-2011-4598","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":"digium:asterisk","products":["digium:asterisk"],"type":"null_dereference","year":"2011"},"n_packages":0,"n_references":6,"next":{"headline":"Memory corruption in n/a","id":"CVE-2011-4599"},"packages":[],"prev":{"headline":"Information disclosure in n/a","id":"CVE-2011-4597"},"products":["n/a"],"published":"2011-12-15","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":"2024-08-07","vendors":["n/a"]},"summary":"Remote attackers can crash the Asterisk daemon via crafted SIP requests when automon is enabled, causing denial of service.","url":"https://insights.sbomify.com/CVE-2011-4598/"}
