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-2009-2726 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-2009-2726/ (Markdown: https://insights.sbomify.com/CVE-2009-2726/index.md)","id":"CVE-2009-2726","markdown":"https://insights.sbomify.com/CVE-2009-2726/index.md","name":"CVE-2009-2726","record":{"aliases":["DEBIAN-CVE-2009-2726","GHSA-9w42-v5mm-2ffh"],"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":"none","summary":"Remote attackers can cause denial of service in Asterisk PBX by sending SIP packets with large sequences of ASCII decimal characters.","user_interaction":"not_required","vuln_class":"denial_of_service"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"asterisk","vendor":"digium"},{"product":"s800i_firmware","vendor":"digium"}],"cvss":{"score":7.8,"severity":"high","source":"nvd","vector":"AV:N/AC:L/Au:N/C:N/I:N/A:C","version":"2.0"},"cwes":[{"id":"CWE-770","name":"Allocation of Resources Without Limits or Throttling"}],"description":"The SIP channel driver in Asterisk Open Source 1.2.x before 1.2.34, 1.4.x before 1.4.26.1, 1.6.0.x before 1.6.0.12, and 1.6.1.x before 1.6.1.4; Asterisk Business Edition A.x.x, B.x.x before B.2.5.9, C.2.x before C.2.4.1, and C.3.x before C.3.1; and Asterisk Appliance s800i 1.2.x before 1.3.0.3 does not use a maximum width when invoking sscanf style functions, which allows remote attackers to cause a denial of service (stack memory consumption) via SIP packets containing large sequences of ASCII decimal characters, as demonstrated via vectors related to (1) the CSeq value in a SIP header, (2) large Content-Length value, and (3) SDP.","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-2009-2726","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":"digium:asterisk","products":["digium:asterisk"],"type":"denial_of_service","year":"2009"},"n_packages":0,"n_references":7,"next":{"headline":"Memory corruption in n/a","id":"CVE-2009-2727"},"packages":[],"prev":{"headline":"Race condition in n/a","id":"CVE-2009-2724"},"products":["n/a"],"published":"2009-08-12","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":"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 cause denial of service in Asterisk PBX by sending SIP packets with large sequences of ASCII decimal characters.","url":"https://insights.sbomify.com/CVE-2009-2726/"}
