Any signed-in user can exploit it over the network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2020-1595 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-2020-1595/ (Markdown: https://insights.sbomify.com/CVE-2020-1595/index.md)","id":"CVE-2020-1595","markdown":"https://insights.sbomify.com/CVE-2020-1595/index.md","name":"CVE-2020-1595","record":{"aliases":["GHSA-85x5-vr9q-4m59"],"analysis":{"component_type":"server_software","fix_type":"patch","impacts":["code_execution"],"network_reachable":"yes","non_default_config":false,"product_category":"Microsoft SharePoint","requires_auth":"low_privilege","summary":"An attacker can execute arbitrary code by sending specially formatted input to a SharePoint API, requiring user interaction to access the endpoint.","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":9.9,"severity":"critical","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:C/C:H/I:H/A:H/E:P/RL:O/RC:C","version":"3.1"},"cwes":[{"id":"CWE-494","name":"Download of Code Without Integrity Check"}],"description":"\u003cp\u003eA remote code execution vulnerability exists in Microsoft SharePoint where APIs aren't properly protected from unsafe data input.
