It can only be exploited from the same machine or local network, and only if a user opens a file or follows a link.\nExploitation: Yes. Attackers have exploited CVE-2017-11826 in the wild since at least 3 Mar 2022.\n\nAffected product: Microsoft Office Compatibility Pack. 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-2017-11826/ (Markdown: https://insights.sbomify.com/CVE-2017-11826/index.md)","id":"CVE-2017-11826","markdown":"https://insights.sbomify.com/CVE-2017-11826/index.md","name":"CVE-2017-11826","record":{"aliases":["GHSA-4qcg-gx82-4h36"],"analysis":{"component_type":"desktop_application","fix_type":"patch","impacts":["code_execution"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Microsoft Office","requires_auth":"none","summary":"Remote attackers can execute arbitrary code by exploiting improper memory handling in Microsoft Office and related server components.","user_interaction":"required","vuln_class":"memory_corruption"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"microsoft","cpe":[{"product":"office_compatibility_pack","vendor":"microsoft"},{"product":"office_online_server","vendor":"microsoft"},{"product":"office_web_apps_server","vendor":"microsoft"},{"product":"office_word_viewer","vendor":"microsoft"},{"product":"sharepoint_enterprise_server","vendor":"microsoft"},{"product":"sharepoint_server","vendor":"microsoft"},{"product":"word","vendor":"microsoft"}],"cvss":{"score":7.8,"severity":"high","source":"cisa-adp","vector":"CVSS:3.1/AV:L/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-119","name":"Improper Restriction of Operations within the Bounds of a Memory Buffer"}],"description":"Microsoft Office 2010, SharePoint Enterprise Server 2010, SharePoint Server 2010, Web Applications, Office Web Apps Server 2010 and 2013, Word Viewer, Word 2007, 2010, 2013 and 2016, Word Automation Services, and Office Online Server allow remote code execution when the software fails to properly handle objects in memory.","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":"2018-02-09","github_poc":1,"max_poc_stars":8,"metasploit":0,"nuclei":0,"refs":[{"date":"2018-02-09T17:20:53Z","kind":"github_poc","ref":"https://github.com/thatskriptkid/CVE-2017-11826","stars":8,"title":"Exploit for CVE-2017-11826"}],"tier":"exploited"},"has_fix":null,"headline":"Microsoft Office Remote Code Execution","id":"CVE-2017-11826","indexable":true,"kev":{"dateAdded":"2022-03-03","dueDate":"2022-03-24","knownRansomwareCampaignUse":"Unknown","product":"Office","requiredAction":"Apply updates per vendor instructions.","vendorProject":"Microsoft","vulnerabilityName":"Microsoft Office Remote Code Execution Vulnerability"},"kind":"cve","links":{"ecosystem":null,"product":"microsoft:office_compatibility_pack","products":["microsoft:office_compatibility_pack","microsoft:office_online_server","microsoft:office_web_apps_server","microsoft:sharepoint_enterprise_server","microsoft:sharepoint_server","microsoft:word"],"type":"memory_corruption","year":"2017"},"n_packages":0,"n_references":6,"next":{"headline":"Memory corruption in Internet Explorer, Microsoft Edge","id":"CVE-2017-11827"},"packages":[],"prev":{"headline":"Memory corruption in Microsoft Office 2016, Microsoft Office 2016 for Mac","id":"CVE-2017-11825"},"products":["Microsoft Office"],"published":"2017-10-13","related":[{"cvss_score":7.8,"headline":"Microsoft Word Remote Code Execution","id":"CVE-2012-2539","kev_date_added":"2022-03-28","published":"2012-12-12"},{"cvss_score":9.3,"headline":"Memory corruption in n/a","id":"CVE-2015-1759","kev_date_added":null,"published":"2015-06-10"},{"cvss_score":9.3,"headline":"Use after free in n/a","id":"CVE-2015-1651","kev_date_added":null,"published":"2015-04-14"},{"cvss_score":9.3,"headline":"Code injection in n/a","id":"CVE-2014-6356","kev_date_added":null,"published":"2014-12-11"},{"cvss_score":9.3,"headline":"Code injection in n/a","id":"CVE-2014-6333","kev_date_added":null,"published":"2014-11-11"},{"cvss_score":9.3,"headline":"Memory corruption in n/a","id":"CVE-2014-6334","kev_date_added":null,"published":"2014-11-11"}],"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":"open","licence":"CC0 1.0","name":"CISA KEV"},{"class":"attribution","licence":"CWE Terms of Use","name":"CWE (MITRE)"},{"class":"attribution","licence":"FIRST CVSS licence","name":"CVSS (FIRST)"},{"class":"open","licence":"CC0","name":"PoC-in-GitHub"}],"ssvc":{"automatable":"no","exploitation":"active","technical_impact":"total"},"state":"PUBLISHED","updated":"2025-10-21","vendors":["Microsoft Corporation"]},"summary":"Remote attackers can execute arbitrary code by exploiting improper memory handling in Microsoft Office and related server components.","url":"https://insights.sbomify.com/CVE-2017-11826/"}
