An attacker can exploit it over the internet without logging in, and only if a user opens a file or follows a link.\nExploitation: There is no known exploitation of CVE-2020-16884 in the wild and no public exploit code.\n\nAffected product: Microsoft Edge. 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-2020-16884/ (Markdown: https://insights.sbomify.com/CVE-2020-16884/index.md)","id":"CVE-2020-16884","markdown":"https://insights.sbomify.com/CVE-2020-16884/index.md","name":"CVE-2020-16884","record":{"aliases":["GHSA-6pf2-gv4h-7wj3"],"analysis":{"component_type":"browser","fix_type":"patch","impacts":["code_execution","privilege_escalation"],"network_reachable":"yes","non_default_config":false,"product_category":"Internet Explorer BHO","requires_auth":"none","summary":"Remote code execution via memory corruption in IEToEdge BHO allows attackers to execute arbitrary code with user privileges.","user_interaction":"required","vuln_class":"memory_corruption"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"microsoft","cpe":[{"product":"edge","vendor":"microsoft"}],"cvss":{"score":4.2,"severity":"medium","source":"cna","vector":"CVSS:3.1/AV:N/AC:H/PR:N/UI:R/S:U/C:L/I:L/A:N/E:P/RL:O/RC:C","version":"3.1"},"cwes":[{"id":"CWE-787","name":"Out-of-bounds Write"}],"description":"\u003cp\u003eA remote code execution vulnerability exists in the way that the IEToEdge Browser Helper Object (BHO) plugin on Internet Explorer handles objects in memory. The vulnerability could corrupt memory in such a way that an attacker could execute arbitrary code in the context of the current user. An attacker who successfully exploited the vulnerability could gain the same user rights as the current user.\u003c/p\u003e\n\u003cp\u003eIn a web-based attack scenario, an attacker could host a specially crafted website that is designed to exploit this vulnerability and then convince a user to view the website. An attacker would have no way to force users to view the attacker-controlled content. Instead, an attacker would have to convince users to take action, typically by getting them to click a link in an email message or in an Instant Messenger message that takes users to the attacker's website, or by opening an attachment sent through email. If the current user is logged on with administrative user rights, an attacker who successfully exploited the vulnerability could take control of an affected system. An attacker could then install programs; view, change, or delete data; or create new accounts with full user rights.\u003c/p\u003e\n\u003cp\u003eThe security update addresses the vulnerability by modifying how the IEToEdge BHO plug-in handles objects in memory.\u003c/p\u003e","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":"Internet Explorer Browser Helper Object (BHO) Memory Corruption Vulnerability","id":"CVE-2020-16884","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":"microsoft:edge","products":["microsoft:edge"],"type":"memory_corruption","year":"2020"},"n_packages":0,"n_references":1,"next":{"headline":"Windows Storage VSP Driver Elevation of Privilege Vulnerability","id":"CVE-2020-16885"},"packages":[],"prev":{"headline":"Visual Studio JSON Remote Code Execution Vulnerability","id":"CVE-2020-16881"},"products":["Microsoft Edge (Chromium-based)"],"published":"2020-09-11","related":[{"cvss_score":8.8,"headline":"Microsoft Internet Explorer Memory Corruption","id":"CVE-2021-26411","kev_date_added":"2021-11-03","published":"2021-03-11"},{"cvss_score":8.8,"headline":"Microsoft Edge Memory Corruption","id":"CVE-2016-7200","kev_date_added":"2022-03-28","published":"2016-11-10"},{"cvss_score":8.8,"headline":"Microsoft Edge Memory Corruption","id":"CVE-2016-7201","kev_date_added":"2022-03-28","published":"2016-11-10"},{"cvss_score":8.1,"headline":"Microsoft Edge and Internet Explorer Type Confusion","id":"CVE-2017-0037","kev_date_added":"2022-03-28","published":"2017-02-26"},{"cvss_score":6.5,"headline":"Microsoft Internet Explorer and Edge Information Disclosure","id":"CVE-2016-3351","kev_date_added":"2022-05-24","published":"2016-09-14"},{"cvss_score":9.8,"headline":"Memory corruption in Microsoft ChakraCore","id":"CVE-2017-0028","kev_date_added":null,"published":"2017-07-14"},{"cvss_score":9.8,"headline":"ChakraCore RCE Vulnerability","id":"CVE-2017-0223","kev_date_added":null,"published":"2017-05-15"}],"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":"no","exploitation":"none","technical_impact":"partial"},"state":"PUBLISHED","updated":"2024-11-18","vendors":["Microsoft"]},"summary":"Remote code execution via memory corruption in IEToEdge BHO allows attackers to execute arbitrary code with user privileges.","url":"https://insights.sbomify.com/CVE-2020-16884/"}
