An attacker can exploit it over the internet without logging in, and only if a user opens a file or follows a link.\nExploitation: Yes. Attackers have exploited CVE-2019-0541 in the wild since at least 3 Nov 2021.\n\nAffected product: Microsoft Excel Viewer. 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-2019-0541/ (Markdown: https://insights.sbomify.com/CVE-2019-0541/index.md)","id":"CVE-2019-0541","markdown":"https://insights.sbomify.com/CVE-2019-0541/index.md","name":"CVE-2019-0541","record":{"aliases":["GHSA-f832-7fhg-m78h"],"analysis":{"component_type":"browser","fix_type":"patch","impacts":["code_execution"],"network_reachable":"yes","non_default_config":false,"product_category":"Microsoft Office and IE","requires_auth":"none","summary":"Remote attackers can execute arbitrary code via improper input validation in the MSHTML engine affecting Internet Explorer and Microsoft Office.","user_interaction":"required","vuln_class":"code_injection"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"microsoft","cpe":[{"product":"excel_viewer","vendor":"microsoft"},{"product":"internet_explorer","vendor":"microsoft"},{"product":"office","vendor":"microsoft"},{"product":"office_365_proplus","vendor":"microsoft"},{"product":"office_word_viewer","vendor":"microsoft"}],"cvss":{"score":8.8,"severity":"high","source":"cisa-adp","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-77","name":"Improper Neutralization of Special Elements used in a Command"}],"description":"A remote code execution vulnerability exists in the way that the MSHTML engine inproperly validates input, aka \"MSHTML Engine Remote Code Execution Vulnerability.\" This affects Microsoft Office, Microsoft Office Word Viewer, Internet Explorer 9, Internet Explorer 11, Microsoft Excel Viewer, Internet Explorer 10, Office 365 ProPlus.","ecosystems":[],"exploits":{"exploitdb":1,"first_seen":"2019-03-13","github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[{"date":"2019-03-13","kind":"exploitdb","ref":"46536","stars":null,"title":"Microsoft Windows MSHTML Engine - 'Edit' Remote Code Execution"}],"tier":"exploited"},"has_fix":null,"headline":"Microsoft MSHTML Remote Code Execution","id":"CVE-2019-0541","indexable":true,"kev":{"dateAdded":"2021-11-03","dueDate":"2022-05-03","knownRansomwareCampaignUse":"Unknown","product":"MSHTML","requiredAction":"Apply updates per vendor instructions.","vendorProject":"Microsoft","vulnerabilityName":"Microsoft MSHTML Remote Code Execution Vulnerability"},"kind":"cve","links":{"ecosystem":null,"product":"microsoft:excel_viewer","products":["microsoft:excel_viewer","microsoft:internet_explorer","microsoft:office","microsoft:office_365_proplus"],"type":"code_injection","year":"2019"},"n_packages":0,"n_references":3,"next":{"headline":"xterm vulnerable to remote code execution","id":"CVE-2019-0542"},"packages":[],"prev":{"headline":"Security feature bypass in Microsoft Excel Viewer","id":"CVE-2019-0540"},"products":["Internet Explorer 10","Internet Explorer 11","Internet Explorer 9","Microsoft Excel Viewer","Microsoft Office","Microsoft Office Word Viewer","Office"],"published":"2019-01-08","related":[{"cvss_score":8.8,"headline":"Microsoft PowerPoint Memory Corruption","id":"CVE-2015-2424","kev_date_added":"2022-03-03","published":"2015-07-14"},{"cvss_score":7.8,"headline":"Microsoft Graphics Component Memory Corruption","id":"CVE-2013-3906","kev_date_added":"2022-02-15","published":"2013-11-06"},{"cvss_score":9.3,"headline":"Memory corruption in n/a","id":"CVE-2008-0113","kev_date_added":null,"published":"2008-03-11"},{"cvss_score":7.8,"headline":"Memory corruption in Microsoft Excel Viewer","id":"CVE-2018-8432","kev_date_added":null,"published":"2018-10-10"},{"cvss_score":5.5,"headline":"Security feature bypass in Microsoft Excel Viewer","id":"CVE-2019-0540","kev_date_added":null,"published":"2019-03-06"},{"cvss_score":5.5,"headline":"Information disclosure in Microsoft Excel Viewer","id":"CVE-2018-8427","kev_date_added":null,"published":"2018-10-10"}],"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":"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":"attribution","licence":"GPL-2.0-or-later","name":"Exploit-DB"}],"ssvc":{"automatable":"no","exploitation":"active","technical_impact":"total"},"state":"PUBLISHED","updated":"2025-10-21","vendors":["Microsoft"]},"summary":"Remote attackers can execute arbitrary code via improper input validation in the MSHTML engine affecting Internet Explorer and Microsoft Office.","url":"https://insights.sbomify.com/CVE-2019-0541/"}
