It can only be exploited from the same machine or local network, with no action from the victim.\nExploitation: It is not confirmed as exploited in the wild, but public exploit code for CVE-2006-6696 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-2006-6696/ (Markdown: https://insights.sbomify.com/CVE-2006-6696/index.md)","id":"CVE-2006-6696","markdown":"https://insights.sbomify.com/CVE-2006-6696/index.md","name":"CVE-2006-6696","record":{"aliases":["GHSA-fmp2-4wcx-jwx4"],"analysis":{"component_type":"operating_system","fix_type":"patch","impacts":["privilege_escalation"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Microsoft Windows OS","requires_auth":"low_privilege","summary":"Local attackers can escalate privileges by triggering a double free in CSRSS via crafted MessageBox calls in Microsoft Windows.","user_interaction":"not_required","vuln_class":"use_after_free"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"windows_2000","vendor":"microsoft"},{"product":"windows_2003_server","vendor":"microsoft"},{"product":"windows_vista","vendor":"microsoft"},{"product":"windows_xp","vendor":"microsoft"}],"cvss":{"score":6.9,"severity":"medium","source":"nvd","vector":"AV:L/AC:M/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":"Double free vulnerability in Microsoft Windows 2000, XP, 2003, and Vista allows local users to gain privileges by calling the MessageBox function with a MB_SERVICE_NOTIFICATION message with crafted data, which sends a HardError message to Client/Server Runtime Server Subsystem (CSRSS) process, which is not properly handled when invoking the UserHardError and GetHardErrorText functions in WINSRV.DLL.","ecosystems":[],"exploits":{"exploitdb":2,"first_seen":"2006-12-20","github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[{"date":"2006-12-20","kind":"exploitdb","ref":"2967","stars":null,"title":"Microsoft Windows - 'MessageBox' Memory Corruption Local Denial of Service"},{"date":"2006-12-27","kind":"exploitdb","ref":"3024","stars":null,"title":"Microsoft Windows - NtRaiseHardError 'Csrss.exe' Memory Disclosure"}],"tier":"weaponised"},"has_fix":null,"headline":"Use after free in n/a","id":"CVE-2006-6696","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":"microsoft:windows_2000","products":["microsoft:windows_2000","microsoft:windows_2003_server","microsoft:windows_vista","microsoft:windows_xp"],"type":"use_after_free","year":"2006"},"n_packages":0,"n_references":24,"next":{"headline":"Other in n/a","id":"CVE-2006-6697"},"packages":[],"prev":{"headline":"Cross-site scripting in n/a","id":"CVE-2006-6695"},"products":["n/a"],"published":"2006-12-22","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":"Local attackers can escalate privileges by triggering a double free in CSRSS via crafted MessageBox calls in Microsoft Windows.","url":"https://insights.sbomify.com/CVE-2006-6696/"}
