Any signed-in user can exploit it over the network, and only if a user opens a file or follows a link."},"fix_prompt":"Check this codebase for CVE-2021-42320 and fix it if it is affected.\n\nWhat it is: CVE-2021-42320 is a high-severity vulnerability in Microsoft Sharepoint Enterprise Server, published on 15 Dec 2021. Any signed-in user can exploit it over the network, and only if a user opens a file or follows a link.\nExploitation: There is no known exploitation of CVE-2021-42320 in the wild and no public exploit code.\n\nAffected product: Microsoft Sharepoint Enterprise Server. 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-2021-42320/ (Markdown: https://insights.sbomify.com/CVE-2021-42320/index.md)","id":"CVE-2021-42320","markdown":"https://insights.sbomify.com/CVE-2021-42320/index.md","name":"CVE-2021-42320","record":{"aliases":["GHSA-7f8g-xqpj-293g"],"analysis":{"component_type":"server_software","fix_type":"patch","impacts":["security_bypass"],"network_reachable":"yes","non_default_config":false,"product_category":"SharePoint Server","requires_auth":"low_privilege","summary":"Attackers can spoof content in Microsoft SharePoint Server, potentially misleading users or bypassing security controls.","user_interaction":"required","vuln_class":"other"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"microsoft","cpe":[{"product":"sharepoint_enterprise_server","vendor":"microsoft"},{"product":"sharepoint_server","vendor":"microsoft"}],"cvss":{"score":8,"severity":"high","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:R/S:U/C:H/I:H/A:H/E:U/RL:O/RC:C","version":"3.1"},"cwes":[{"id":"CWE-290","name":"Authentication Bypass by Spoofing"}],"description":"Microsoft SharePoint Server Spoofing 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":"Microsoft SharePoint Server Spoofing Vulnerability","id":"CVE-2021-42320","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":"microsoft:sharepoint_enterprise_server","products":["microsoft:sharepoint_enterprise_server","microsoft:sharepoint_server"],"type":"other","year":"2021"},"n_packages":0,"n_references":1,"next":{"headline":"Microsoft Exchange Server Remote Code Execution","id":"CVE-2021-42321"},"packages":[],"prev":{"headline":"Visual Studio Elevation of Privilege Vulnerability","id":"CVE-2021-42319"},"products":["Microsoft SharePoint Enterprise Server 2016","Microsoft SharePoint Server 2019","Microsoft SharePoint Server Subscription Edition"],"published":"2021-12-15","related":[{"cvss_score":9.8,"headline":"Microsoft SharePoint Remote Code Execution","id":"CVE-2019-0604","kev_date_added":"2021-11-03","published":"2019-03-06"},{"cvss_score":7.2,"headline":"Microsoft SharePoint Server Code Injection","id":"CVE-2023-24955","kev_date_added":"2024-03-26","published":"2023-05-09"},{"cvss_score":6.5,"headline":"Microsoft SharePoint Improper Authentication","id":"CVE-2025-49706","kev_date_added":"2025-07-22","published":"2025-07-08"},{"cvss_score":9.9,"headline":"Microsoft SharePoint Remote Code Execution Vulnerability","id":"CVE-2020-1210","kev_date_added":null,"published":"2020-09-11"},{"cvss_score":9.9,"headline":"Microsoft SharePoint Remote Code Execution Vulnerability","id":"CVE-2020-1595","kev_date_added":null,"published":"2020-09-11"},{"cvss_score":8.8,"headline":"Microsoft SharePoint Server Remote Code Execution Vulnerability","id":"CVE-2025-47163","kev_date_added":null,"published":"2025-06-10"},{"cvss_score":8.8,"headline":"Microsoft SharePoint Server Remote Code Execution Vulnerability","id":"CVE-2025-47166","kev_date_added":null,"published":"2025-06-10"}],"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":"2024-08-04","vendors":["Microsoft"]},"summary":"Attackers can spoof content in Microsoft SharePoint Server, potentially misleading users or bypassing security controls.","url":"https://insights.sbomify.com/CVE-2021-42320/"}
