It can only be exploited from the same machine or local network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2009-2516 in the wild and no public exploit code.\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-2009-2516/ (Markdown: https://insights.sbomify.com/CVE-2009-2516/index.md)","id":"CVE-2009-2516","markdown":"https://insights.sbomify.com/CVE-2009-2516/index.md","name":"CVE-2009-2516","record":{"aliases":["GHSA-24fj-8422-2v9w"],"analysis":{"component_type":"operating_system","fix_type":"patch","impacts":["privilege_escalation"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Windows Kernel","requires_auth":"low_privilege","summary":"Local attackers can gain privileges by exploiting a NULL pointer dereference in the Windows kernel via a crafted PE file.","user_interaction":"not_required","vuln_class":"null_dereference"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"microsoft","cpe":[{"product":"windows_2000","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":7.1,"severity":"high","source":"cisa-adp","vector":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:N/A:H","version":"3.1"},"cwes":[{"id":"CWE-20","name":"Improper Input Validation"},{"id":"CWE-476","name":"NULL Pointer Dereference"}],"description":"The kernel in Microsoft Windows 2000 SP4, XP SP2 and SP3, Server 2003 SP2, Vista Gold and SP1, and Server 2008 Gold does not properly validate data sent from user mode, which allows local users to gain privileges via a crafted PE .exe file that triggers a NULL pointer dereference during chain traversal, aka \"Windows Kernel NULL Pointer Dereference Vulnerability.\"","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":"Null dereference in n/a","id":"CVE-2009-2516","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":"microsoft:windows_2000","products":["microsoft:windows_2000","microsoft:windows_server_2003","microsoft:windows_server_2008","microsoft:windows_vista","microsoft:windows_xp"],"type":"null_dereference","year":"2009"},"n_packages":0,"n_references":4,"next":{"headline":"Denial of service in n/a","id":"CVE-2009-2517"},"packages":[],"prev":{"headline":"Integer overflow in n/a","id":"CVE-2009-2515"},"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)"}],"ssvc":{"automatable":"no","exploitation":"none","technical_impact":"partial"},"state":"PUBLISHED","updated":"2025-01-21","vendors":["n/a"]},"summary":"Local attackers can gain privileges by exploiting a NULL pointer dereference in the Windows kernel via a crafted PE file.","url":"https://insights.sbomify.com/CVE-2009-2516/"}
