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-2007-5538 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-2007-5538/ (Markdown: https://insights.sbomify.com/CVE-2007-5538/index.md)","id":"CVE-2007-5538","markdown":"https://insights.sbomify.com/CVE-2007-5538/index.md","name":"CVE-2007-5538","record":{"aliases":["GHSA-76f8-93vw-4mch"],"analysis":{"component_type":"server_software","fix_type":"upgrade","impacts":["code_execution","denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"Cisco Unified Communications Manager","requires_auth":"none","summary":"Remote attackers can execute arbitrary code or cause denial of service via a buffer overflow in the TFTP service of Cisco Unified Communications Manager.","user_interaction":"not_required","vuln_class":"memory_corruption"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"unified_callmanager","vendor":"cisco"},{"product":"unified_communications_manager","vendor":"cisco"}],"cvss":{"score":10,"severity":"critical","source":"nvd","vector":"AV:N/AC:L/Au:N/C:C/I:C/A:C","version":"2.0"},"cwes":[{"id":"CWE-119","name":"Improper Restriction of Operations within the Bounds of a Memory Buffer"}],"description":"Buffer overflow in the Centralized TFTP File Locator Service in Cisco Unified Communications Manager (CUCM, formerly CallManager) 5.1 before 5.1(3), and Unified CallManager 5.0, allows remote attackers to execute arbitrary code or cause a denial of service via unspecified vectors involving the processing of filenames, aka CSCsh47712.","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":"Memory corruption in n/a","id":"CVE-2007-5538","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":"cisco:unified_communications_manager","products":["cisco:unified_communications_manager"],"type":"memory_corruption","year":"2007"},"n_packages":0,"n_references":7,"next":{"headline":"Privilege escalation in n/a","id":"CVE-2007-5539"},"packages":[],"prev":{"headline":"Denial of service in n/a","id":"CVE-2007-5537"},"products":["n/a"],"published":"2007-10-18","related":[{"cvss_score":10,"headline":"Memory corruption in n/a","id":"CVE-2008-0027","kev_date_added":null,"published":"2008-01-17"},{"cvss_score":10,"headline":"Integer overflow in n/a","id":"CVE-2006-5278","kev_date_added":null,"published":"2007-07-15"},{"cvss_score":9.3,"headline":"Memory corruption in n/a","id":"CVE-2006-5277","kev_date_added":null,"published":"2007-07-15"},{"cvss_score":7.8,"headline":"Denial of service in n/a","id":"CVE-2009-2864","kev_date_added":null,"published":"2009-09-28"},{"cvss_score":7.8,"headline":"Denial of service in n/a","id":"CVE-2008-1744","kev_date_added":null,"published":"2008-05-16"},{"cvss_score":7.8,"headline":"Denial of service in n/a","id":"CVE-2007-5537","kev_date_added":null,"published":"2007-10-18"}],"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 execute arbitrary code or cause denial of service via a buffer overflow in the TFTP service of Cisco Unified Communications Manager.","url":"https://insights.sbomify.com/CVE-2007-5538/"}
