An attacker can exploit it over the internet without logging in, and only if a user opens a file or follows a link.\nExploitation: There is no known exploitation of CVE-2020-0647 in the wild and no public exploit code.\n\nAffected product: Microsoft Office Online 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-2020-0647/ (Markdown: https://insights.sbomify.com/CVE-2020-0647/index.md)","id":"CVE-2020-0647","markdown":"https://insights.sbomify.com/CVE-2020-0647/index.md","name":"CVE-2020-0647","record":{"aliases":["GHSA-r3cv-6vrm-m2pf"],"analysis":{"component_type":"server_software","fix_type":"patch","impacts":["security_bypass"],"network_reachable":"yes","non_default_config":false,"product_category":"Office Online Server","requires_auth":"none","summary":"Attackers can spoof content in Microsoft Office Online due to improper origin validation in cross-origin communications.","user_interaction":"required","vuln_class":"other"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"microsoft","cpe":[{"product":"office_online_server","vendor":"microsoft"}],"cvss":{"score":5.4,"severity":"medium","source":"nvd","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:L/I:L/A:N","version":"3.1"},"cwes":[{"id":"CWE-346","name":"Origin Validation Error"}],"description":"A spoofing vulnerability exists when Office Online does not validate origin in cross-origin communications correctly, aka 'Microsoft Office Online 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":"Other in Office Online Server","id":"CVE-2020-0647","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":"microsoft:office_online_server","products":["microsoft:office_online_server"],"type":"other","year":"2020"},"n_packages":0,"n_references":1,"next":{"headline":"Windows RSoP Service Application Elevation of Privilege Vulnerability","id":"CVE-2020-0648"},"packages":[],"prev":{"headline":"Microsoft .NET Framework Remote Code Execution","id":"CVE-2020-0646"},"products":["Office Online Server"],"published":"2020-01-14","related":[{"cvss_score":7.8,"headline":"Microsoft Excel Remote Code Execution Vulnerability","id":"CVE-2022-33648","kev_date_added":null,"published":"2022-08-09"},{"cvss_score":7.8,"headline":"Memory corruption in Microsoft Office","id":"CVE-2017-8743","kev_date_added":null,"published":"2017-09-13"},{"cvss_score":6.5,"headline":"Microsoft Excel Denial of Service Vulnerability","id":"CVE-2023-23396","kev_date_added":null,"published":"2023-03-14"},{"cvss_score":6.1,"headline":"Cross-site scripting in Microsoft Office Online Server","id":"CVE-2020-1442","kev_date_added":null,"published":"2020-07-14"},{"cvss_score":5.5,"headline":"Microsoft Office Information Disclosure Vulnerability","id":"CVE-2022-30159","kev_date_added":null,"published":"2022-06-15"},{"cvss_score":5.5,"headline":"Microsoft Office Information Disclosure Vulnerability","id":"CVE-2022-30171","kev_date_added":null,"published":"2022-06-15"},{"cvss_score":5.5,"headline":"Microsoft Office Information Disclosure Vulnerability","id":"CVE-2022-30172","kev_date_added":null,"published":"2022-06-15"}],"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 Office Online due to improper origin validation in cross-origin communications.","url":"https://insights.sbomify.com/CVE-2020-0647/"}
