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-2002-1561 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-2002-1561/ (Markdown: https://insights.sbomify.com/CVE-2002-1561/index.md)","id":"CVE-2002-1561","markdown":"https://insights.sbomify.com/CVE-2002-1561/index.md","name":"CVE-2002-1561","record":{"aliases":["GHSA-vff3-5vfq-9m5f"],"analysis":{"component_type":"operating_system","fix_type":"patch","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"Windows RPC service","requires_auth":"none","summary":"Remote attackers can disable the RPC service on Windows systems by sending a malformed packet to the Endpoint Mapper, causing a denial of service.","user_interaction":"not_required","vuln_class":"null_dereference"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"windows_2000","vendor":"microsoft"},{"product":"windows_2000_terminal_services","vendor":"microsoft"},{"product":"windows_nt","vendor":"microsoft"},{"product":"windows_xp","vendor":"microsoft"}],"cvss":{"score":5,"severity":"medium","source":"nvd","vector":"AV:N/AC:L/Au:N/C:N/I:N/A:P","version":"2.0"},"cwes":[],"description":"The RPC component in Windows 2000, Windows NT 4.0, and Windows XP allows remote attackers to cause a denial of service (disabled RPC service) via a malformed packet to the RPC Endpoint Mapper at TCP port 135, which triggers a null pointer dereference.","ecosystems":[],"exploits":{"exploitdb":4,"first_seen":"2002-10-18","github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[{"date":"2002-10-18","kind":"exploitdb","ref":"21953","stars":null,"title":"Microsoft Windows XP/2000/NT 4.0 - RPC Service Denial of Service (3)"},{"date":"2002-10-18","kind":"exploitdb","ref":"21954","stars":null,"title":"Microsoft Windows XP/2000/NT 4.0 - RPC Service Denial of Service (4)"},{"date":"2002-10-22","kind":"exploitdb","ref":"21951","stars":null,"title":"Microsoft Windows XP/2000/NT 4.0 - RPC Service Denial of Service (1)"},{"date":"2002-10-22","kind":"exploitdb","ref":"21952","stars":null,"title":"Microsoft Windows XP/2000/NT 4.0 - RPC Service Denial of Service (2)"}],"tier":"weaponised"},"has_fix":null,"headline":"Null dereference in n/a","id":"CVE-2002-1561","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":"microsoft:windows_2000","products":["microsoft:windows_2000","microsoft:windows_nt","microsoft:windows_xp"],"type":"null_dereference","year":"2002"},"n_packages":0,"n_references":5,"next":{"headline":"Path traversal in n/a","id":"CVE-2002-1562"},"packages":[],"prev":{"headline":"Auth bypass in n/a","id":"CVE-2002-1560"},"products":["n/a"],"published":"2003-03-26","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":"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":"2024-08-08","vendors":["n/a"]},"summary":"Remote attackers can disable the RPC service on Windows systems by sending a malformed packet to the Endpoint Mapper, causing a denial of service.","url":"https://insights.sbomify.com/CVE-2002-1561/"}
