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-2021-27085 in the wild since at least 3 Nov 2021.\n\nAffected product: Microsoft Internet Explorer. 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-2021-27085/ (Markdown: https://insights.sbomify.com/CVE-2021-27085/index.md)","id":"CVE-2021-27085","markdown":"https://insights.sbomify.com/CVE-2021-27085/index.md","name":"CVE-2021-27085","record":{"aliases":["GHSA-vm76-5x29-7jx8"],"analysis":{"component_type":"browser","fix_type":"patch","impacts":["code_execution"],"network_reachable":"yes","non_default_config":false,"product_category":"Internet Explorer browser","requires_auth":"none","summary":"Attackers can execute arbitrary code on systems using Internet Explorer, requiring users to apply Microsoft security patches.","user_interaction":"required","vuln_class":"code_injection"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"microsoft","cpe":[{"product":"internet_explorer","vendor":"microsoft"}],"cvss":{"score":8.8,"severity":"high","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:C/C:L/I:H/A:L/E:P/RL:O/RC:C","version":"3.1"},"cwes":[],"description":"Internet Explorer Remote Code Execution Vulnerability","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"exploited"},"has_fix":null,"headline":"Microsoft Internet Explorer Remote Code Execution","id":"CVE-2021-27085","indexable":true,"kev":{"dateAdded":"2021-11-03","dueDate":"2021-11-17","knownRansomwareCampaignUse":"Unknown","product":"Internet Explorer","requiredAction":"Apply updates per vendor instructions.","vendorProject":"Microsoft","vulnerabilityName":"Microsoft Internet Explorer Remote Code Execution Vulnerability"},"kind":"cve","links":{"ecosystem":null,"product":"microsoft:internet_explorer","products":["microsoft:internet_explorer"],"type":"code_injection","year":"2021"},"n_packages":0,"n_references":1,"next":{"headline":"Windows Services and Controller App Elevation of Privilege Vulnerability","id":"CVE-2021-27086"},"packages":[],"prev":{"headline":"Visual Studio Code Java Extension Pack Remote Code Execution Vulnerability","id":"CVE-2021-27084"},"products":["Internet Explorer 11"],"published":"2021-03-11","related":[{"cvss_score":9.8,"headline":"Microsoft Internet Explorer Memory Corruption","id":"CVE-2014-1776","kev_date_added":"2022-01-28","published":"2014-04-27"},{"cvss_score":8.8,"headline":"Microsoft Internet Explorer Remote Code Execution","id":"CVE-2017-0222","kev_date_added":"2022-02-25","published":"2017-05-12"},{"cvss_score":8.8,"headline":"Microsoft Internet Explorer Privilege Escalation","id":"CVE-2017-0210","kev_date_added":"2022-05-24","published":"2017-04-12"},{"cvss_score":8.8,"headline":"Microsoft Internet Explorer Memory Corruption","id":"CVE-2017-0149","kev_date_added":"2022-05-24","published":"2017-03-17"},{"cvss_score":8.8,"headline":"Microsoft Internet Explorer Memory Corruption","id":"CVE-2015-2502","kev_date_added":"2022-04-13","published":"2015-08-19"},{"cvss_score":8.8,"headline":"Microsoft Internet Explorer Memory Corruption","id":"CVE-2015-2419","kev_date_added":"2022-03-28","published":"2015-07-14"}],"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":"FIRST CVSS licence","name":"CVSS (FIRST)"}],"ssvc":{"automatable":"no","exploitation":"active","technical_impact":"partial"},"state":"PUBLISHED","updated":"2026-08-19","vendors":["Microsoft"]},"summary":"Attackers can execute arbitrary code on systems using Internet Explorer, requiring users to apply Microsoft security patches.","url":"https://insights.sbomify.com/CVE-2021-27085/"}
