Any signed-in user can exploit it over the network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2020-1439 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-2020-1439/ (Markdown: https://insights.sbomify.com/CVE-2020-1439/index.md)","id":"CVE-2020-1439","markdown":"https://insights.sbomify.com/CVE-2020-1439/index.md","name":"CVE-2020-1439","record":{"aliases":["GHSA-7vrg-q6mv-3q9x"],"analysis":{"component_type":"server_software","fix_type":"patch","impacts":["code_execution"],"network_reachable":"yes","non_default_config":false,"product_category":"SharePoint Server","requires_auth":"low_privilege","summary":"Remote attackers can execute arbitrary code on SharePoint Server via unsafe XML deserialization in PerformancePoint Services.","user_interaction":"not_required","vuln_class":"deserialization"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"microsoft","cpe":[{"product":"sharepoint_enterprise_server","vendor":"microsoft"},{"product":"sharepoint_foundation","vendor":"microsoft"},{"product":"sharepoint_server","vendor":"microsoft"}],"cvss":{"score":8.8,"severity":"high","source":"nvd","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-502","name":"Deserialization of Untrusted Data"}],"description":"A remote code execution vulnerability exists in PerformancePoint Services for SharePoint Server when the software fails to check the source markup of XML file input, aka 'PerformancePoint Services Remote Code Execution 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":"Deserialization in Microsoft SharePoint Enterprise Server","id":"CVE-2020-1439","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":"microsoft:sharepoint_enterprise_server","products":["microsoft:sharepoint_enterprise_server","microsoft:sharepoint_foundation","microsoft:sharepoint_server"],"type":"deserialization","year":"2020"},"n_packages":0,"n_references":2,"next":{"headline":"Microsoft SharePoint Server Tampering Vulnerability","id":"CVE-2020-1440"},"packages":[],"prev":{"headline":"Privilege escalation in Windows","id":"CVE-2020-1438"},"products":["Microsoft SharePoint Enterprise Server","Microsoft SharePoint Foundation","Microsoft SharePoint Server"],"published":"2020-07-14","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":"Remote attackers can execute arbitrary code on SharePoint Server via unsafe XML deserialization in PerformancePoint Services.","url":"https://insights.sbomify.com/CVE-2020-1439/"}
