An attacker can exploit it over the internet without logging in, with no action from the victim.\nExploitation: It is not confirmed as exploited in the wild, but public exploit code for CVE-2009-2511 exists.\n\nAffected product: Microsoft Windows 2000. 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-2009-2511/ (Markdown: https://insights.sbomify.com/CVE-2009-2511/index.md)","id":"CVE-2009-2511","markdown":"https://insights.sbomify.com/CVE-2009-2511/index.md","name":"CVE-2009-2511","record":{"aliases":["GHSA-f8c8-v22w-8vv8"],"analysis":{"component_type":"operating_system","fix_type":"patch","impacts":["security_bypass"],"network_reachable":"yes","non_default_config":false,"product_category":"Windows CryptoAPI","requires_auth":"none","summary":"Man-in-the-middle attackers can spoof SSL servers via malformed X.509 certificates exploiting an integer overflow in Windows CryptoAPI.","user_interaction":"not_required","vuln_class":"integer_overflow"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"microsoft","cpe":[{"product":"windows_2000","vendor":"microsoft"},{"product":"windows_7","vendor":"microsoft"},{"product":"windows_server_2003","vendor":"microsoft"},{"product":"windows_server_2008","vendor":"microsoft"},{"product":"windows_vista","vendor":"microsoft"},{"product":"windows_xp","vendor":"microsoft"}],"cvss":{"score":7.5,"severity":"high","source":"nvd","vector":"AV:N/AC:L/Au:N/C:P/I:P/A:P","version":"2.0"},"cwes":[{"id":"CWE-189","name":null}],"description":"Integer overflow in the CryptoAPI component in Microsoft Windows 2000 SP4, Windows XP SP2 and SP3, Windows Server 2003 SP2, Windows Vista Gold, SP1, and SP2, Windows Server 2008 Gold, SP2, and R2, and Windows 7 allows man-in-the-middle attackers to spoof arbitrary SSL servers and other entities via an X.509 certificate that has a malformed ASN.1 Object Identifier (OID) and was issued by a legitimate Certification Authority, aka \"Integer Overflow in X.509 Object Identifiers Vulnerability.\"","ecosystems":[],"exploits":{"exploitdb":1,"first_seen":"2009-08-05","github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[{"date":"2009-08-05","kind":"exploitdb","ref":"33264","stars":null,"title":"Microsoft Internet Explorer 8 - X.509 Certificate Common Name Encoding Multiple Security Bypass Vulnerabilities"}],"tier":"weaponised"},"has_fix":null,"headline":"Integer overflow in n/a","id":"CVE-2009-2511","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":"microsoft:windows_2000","products":["microsoft:windows_2000","microsoft:windows_7","microsoft:windows_server_2003","microsoft:windows_server_2008","microsoft:windows_vista","microsoft:windows_xp"],"type":"integer_overflow","year":"2009"},"n_packages":0,"n_references":3,"next":{"headline":"Memory corruption in n/a","id":"CVE-2009-2512"},"packages":[],"prev":{"headline":"Security feature bypass in n/a","id":"CVE-2009-2510"},"products":["n/a"],"published":"2009-10-14","related":[{"cvss_score":9.8,"headline":"Microsoft Windows Buffer Overflow","id":"CVE-2008-4250","kev_date_added":"2026-05-20","published":"2008-10-23"},{"cvss_score":7.8,"headline":"Microsoft Windows Kernel Exception Handler","id":"CVE-2010-0232","kev_date_added":"2022-03-03","published":"2010-01-21"},{"cvss_score":7.8,"headline":"Microsoft Windows Improper Input Validation","id":"CVE-2009-1123","kev_date_added":"2022-03-03","published":"2009-06-10"},{"cvss_score":7.8,"headline":"Microsoft Windows Privilege Escalation","id":"CVE-2002-0367","kev_date_added":"2022-03-03","published":"2003-04-02"},{"cvss_score":10,"headline":"Memory corruption in n/a","id":"CVE-2010-0269","kev_date_added":null,"published":"2010-04-14"},{"cvss_score":10,"headline":"Weak cryptography in n/a","id":"CVE-2010-0231","kev_date_added":null,"published":"2010-02-10"},{"cvss_score":10,"headline":"Auth bypass in n/a","id":"CVE-2009-3677","kev_date_added":null,"published":"2009-12-09"}],"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)"},{"class":"attribution","licence":"GPL-2.0-or-later","name":"Exploit-DB"}],"ssvc":{"automatable":null,"exploitation":null,"technical_impact":null},"state":"PUBLISHED","updated":"2024-08-07","vendors":["n/a"]},"summary":"Man-in-the-middle attackers can spoof SSL servers via malformed X.509 certificates exploiting an integer overflow in Windows CryptoAPI.","url":"https://insights.sbomify.com/CVE-2009-2511/"}
