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-2011-2561 in the wild and no public exploit code.\n\nAffected product: Cisco Unified Communications Manager. 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-2011-2561/ (Markdown: https://insights.sbomify.com/CVE-2011-2561/index.md)","id":"CVE-2011-2561","markdown":"https://insights.sbomify.com/CVE-2011-2561/index.md","name":"CVE-2011-2561","record":{"aliases":["GHSA-jxqj-hhh8-m26w"],"analysis":{"component_type":"server_software","fix_type":"upgrade","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":true,"product_category":"Cisco Unified Communications Manager","requires_auth":"none","summary":"Remote attackers can cause a service outage in Cisco Unified Communications Manager by sending crafted SIP calls using the g729ar8 codec.","user_interaction":"not_required","vuln_class":"denial_of_service"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"cisco","cpe":[{"product":"unified_communications_manager","vendor":"cisco"}],"cvss":{"score":7.1,"severity":"high","source":"nvd","vector":"AV:N/AC:M/Au:N/C:N/I:N/A:C","version":"2.0"},"cwes":[{"id":"CWE-399","name":null}],"description":"The SIP process in Cisco Unified Communications Manager (aka CUCM, formerly CallManager) 7.x before 7.1(5b)su4 and 8.x before 8.0(1) does not properly handle SDP data within a SIP call in certain situations related to use of the g729ar8 codec for a Media Termination Point (MTP), which allows remote attackers to cause a denial of service (service outage) via a crafted call, aka Bug ID CSCtc61990.","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"none_known"},"has_fix":null,"headline":"Denial of service in n/a","id":"CVE-2011-2561","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":"cisco:unified_communications_manager","products":["cisco:unified_communications_manager"],"type":"denial_of_service","year":"2011"},"n_packages":0,"n_references":1,"next":{"headline":"Denial of service in n/a","id":"CVE-2011-2562"},"packages":[],"prev":{"headline":"Denial of service in n/a","id":"CVE-2011-2560"},"products":["n/a"],"published":"2011-08-29","related":[{"cvss_score":8.6,"headline":"Cisco Unified Communications Manager Server-Side Request Forgery (SSRF)","id":"CVE-2026-20230","kev_date_added":"2026-06-25","published":"2026-06-03"},{"cvss_score":8.2,"headline":"Cisco Unified Communications Products Code Injection","id":"CVE-2026-20045","kev_date_added":"2026-01-21","published":"2026-01-21"},{"cvss_score":10,"headline":"Cisco Unified Communications Manager Static SSH Credentials Vulnerability","id":"CVE-2025-20309","kev_date_added":null,"published":"2025-07-02"},{"cvss_score":10,"headline":"Information disclosure in n/a","id":"CVE-2011-1643","kev_date_added":null,"published":"2011-08-29"},{"cvss_score":9.9,"headline":"Deserialization in Cisco Packaged Contact Center Enterprise","id":"CVE-2024-20253","kev_date_added":null,"published":"2024-01-26"},{"cvss_score":9,"headline":"Information disclosure in n/a","id":"CVE-2009-0632","kev_date_added":null,"published":"2009-03-12"},{"cvss_score":8.8,"headline":"SQL injection in Cisco Unified Communications Manager","id":"CVE-2017-6757","kev_date_added":null,"published":"2017-08-07"}],"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":"2024-09-17","vendors":["n/a"]},"summary":"Remote attackers can cause a service outage in Cisco Unified Communications Manager by sending crafted SIP calls using the g729ar8 codec.","url":"https://insights.sbomify.com/CVE-2011-2561/"}
