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-2009-2053 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-2009-2053/ (Markdown: https://insights.sbomify.com/CVE-2009-2053/index.md)","id":"CVE-2009-2053","markdown":"https://insights.sbomify.com/CVE-2009-2053/index.md","name":"CVE-2009-2053","record":{"aliases":["GHSA-8j74-6x75-vf94"],"analysis":{"component_type":"server_software","fix_type":"upgrade","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"Cisco Unified Communications Manager","requires_auth":"none","summary":"Remote attackers can cause denial of service in Cisco Unified Communications Manager by flooding TCP packets, leading to file-descriptor exhaustion.","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":7.8,"severity":"high","source":"nvd","vector":"AV:N/AC:L/Au:N/C:N/I:N/A:C","version":"2.0"},"cwes":[],"description":"Cisco Unified Communications Manager (aka CUCM, formerly CallManager) 4.x, 5.x before 5.1(3g), 6.x before 6.1(4), 7.0 before 7.0(2a)su1, and 7.1 before 7.1(2) allows remote attackers to cause a denial of service (file-descriptor exhaustion and SCCP outage) via a flood of TCP packets, aka Bug ID CSCsx32236.","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-2009-2053","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":"cisco:unified_communications_manager","products":["cisco:unified_communications_manager"],"type":"denial_of_service","year":"2009"},"n_packages":0,"n_references":6,"next":{"headline":"Denial of service in n/a","id":"CVE-2009-2054"},"packages":[],"prev":{"headline":"Denial of service in n/a","id":"CVE-2009-2052"},"products":["n/a"],"published":"2009-08-27","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":"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 Cisco Unified Communications Manager by flooding TCP packets, leading to file-descriptor exhaustion.","url":"https://insights.sbomify.com/CVE-2009-2053/"}
