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-2021-1718 in the wild and no public exploit code.\n\nAffected product: Microsoft Sharepoint Foundation. 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-2021-1718/ (Markdown: https://insights.sbomify.com/CVE-2021-1718/index.md)","id":"CVE-2021-1718","markdown":"https://insights.sbomify.com/CVE-2021-1718/index.md","name":"CVE-2021-1718","record":{"aliases":["GHSA-c6r7-5wvw-95cj"],"analysis":{"component_type":"server_software","fix_type":"patch","impacts":["data_modify"],"network_reachable":"yes","non_default_config":false,"product_category":"SharePoint Server","requires_auth":"low_privilege","summary":"An attacker can tamper with data in Microsoft SharePoint Server, requiring a patch to mitigate the risk.","user_interaction":"required","vuln_class":"other"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"microsoft","cpe":[{"product":"sharepoint_foundation","vendor":"microsoft"}],"cvss":{"score":8,"severity":"high","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:R/S:U/C:H/I:H/A:H/E:U/RL:O/RC:C","version":"3.1"},"cwes":[],"description":"Microsoft SharePoint Server Tampering 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":"Microsoft SharePoint Server Tampering Vulnerability","id":"CVE-2021-1718","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":"microsoft:sharepoint_foundation","products":["microsoft:sharepoint_foundation"],"type":"other","year":"2021"},"n_packages":0,"n_references":1,"next":{"headline":"Microsoft SharePoint Elevation of Privilege Vulnerability","id":"CVE-2021-1719"},"packages":[],"prev":{"headline":"Microsoft SharePoint Server Spoofing Vulnerability","id":"CVE-2021-1717"},"products":["Microsoft SharePoint Foundation 2010 Service Pack 2"],"published":"2021-01-12","related":[{"cvss_score":9.3,"headline":"Privilege escalation in n/a","id":"CVE-2014-2816","kev_date_added":null,"published":"2014-08-12"},{"cvss_score":8.8,"headline":"Microsoft SharePoint Server Remote Code Execution Vulnerability","id":"CVE-2023-21742","kev_date_added":null,"published":"2023-01-10"},{"cvss_score":8.8,"headline":"Microsoft SharePoint Server Remote Code Execution Vulnerability","id":"CVE-2023-21744","kev_date_added":null,"published":"2023-01-10"},{"cvss_score":8.8,"headline":"Microsoft SharePoint Server Remote Code Execution Vulnerability","id":"CVE-2022-44690","kev_date_added":null,"published":"2022-12-13"},{"cvss_score":8.8,"headline":"Microsoft SharePoint Server Remote Code Execution Vulnerability","id":"CVE-2022-41036","kev_date_added":null,"published":"2022-10-11"},{"cvss_score":8.8,"headline":"Microsoft SharePoint Server Remote Code Execution Vulnerability","id":"CVE-2022-41037","kev_date_added":null,"published":"2022-10-11"},{"cvss_score":8.8,"headline":"Microsoft SharePoint Server Remote Code Execution Vulnerability","id":"CVE-2022-41038","kev_date_added":null,"published":"2022-10-11"}],"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":"FIRST CVSS licence","name":"CVSS (FIRST)"}],"ssvc":{"automatable":"no","exploitation":"none","technical_impact":"total"},"state":"PUBLISHED","updated":"2024-11-19","vendors":["Microsoft"]},"summary":"An attacker can tamper with data in Microsoft SharePoint Server, requiring a patch to mitigate the risk.","url":"https://insights.sbomify.com/CVE-2021-1718/"}
