Any signed-in user can exploit it over the network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2018-8300 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-2018-8300/ (Markdown: https://insights.sbomify.com/CVE-2018-8300/index.md)","id":"CVE-2018-8300","markdown":"https://insights.sbomify.com/CVE-2018-8300/index.md","name":"CVE-2018-8300","record":{"aliases":["GHSA-r894-c8ph-2pv7"],"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":"Attackers can execute arbitrary code remotely by exploiting improper validation of application package markup in Microsoft SharePoint.","user_interaction":"not_required","vuln_class":"code_injection"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"microsoft","cpe":[{"product":"sharepoint_enterprise_server","vendor":"microsoft"}],"cvss":{"score":8.8,"severity":"high","source":"nvd","vector":"CVSS:3.0/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H","version":"3.0"},"cwes":[{"id":"CWE-20","name":"Improper Input Validation"}],"description":"A remote code execution vulnerability exists in Microsoft SharePoint when the software fails to check the source markup of an application package, aka \"Microsoft SharePoint Remote Code Execution Vulnerability.\" This affects Microsoft SharePoint.","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":"Code injection in Microsoft SharePoint","id":"CVE-2018-8300","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":"microsoft:sharepoint_enterprise_server","products":["microsoft:sharepoint_enterprise_server"],"type":"code_injection","year":"2018"},"n_packages":0,"n_references":3,"next":{"headline":"Memory corruption in Microsoft Edge","id":"CVE-2018-8301"},"packages":[],"prev":{"headline":"Cross-site scripting in Microsoft SharePoint","id":"CVE-2018-8299"},"products":["Microsoft SharePoint"],"published":"2018-07-11","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":"2024-08-05","vendors":["Microsoft"]},"summary":"Attackers can execute arbitrary code remotely by exploiting improper validation of application package markup in Microsoft SharePoint.","url":"https://insights.sbomify.com/CVE-2018-8300/"}
