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-2019-0558 in the wild and no public exploit code.\n\nAffected product: Microsoft Sharepoint 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-2019-0558/ (Markdown: https://insights.sbomify.com/CVE-2019-0558/index.md)","id":"CVE-2019-0558","markdown":"https://insights.sbomify.com/CVE-2019-0558/index.md","name":"CVE-2019-0558","record":{"aliases":["GHSA-rvmf-46hh-x3rp"],"analysis":{"component_type":"server_software","fix_type":"patch","impacts":["code_execution","data_read"],"network_reachable":"yes","non_default_config":false,"product_category":"Microsoft SharePoint Server","requires_auth":"low_privilege","summary":"Attackers can execute arbitrary scripts in user browsers via unsanitized web requests in Microsoft SharePoint Server.","user_interaction":"required","vuln_class":"xss"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"microsoft","cpe":[{"product":"business_productivity_servers","vendor":"microsoft"},{"product":"sharepoint_server","vendor":"microsoft"}],"cvss":{"score":5.4,"severity":"medium","source":"cisa-adp","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:R/S:C/C:L/I:L/A:N","version":"3.1"},"cwes":[{"id":"CWE-79","name":"Improper Neutralization of Input During Web Page Generation"}],"description":"A cross-site-scripting (XSS) vulnerability exists when Microsoft SharePoint Server does not properly sanitize a specially crafted web request to an affected SharePoint server, aka \"Microsoft Office SharePoint XSS Vulnerability.\" This affects Microsoft SharePoint Server, Microsoft SharePoint, Microsoft Business Productivity Servers.
