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-2020-0663 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-2020-0663/ (Markdown: https://insights.sbomify.com/CVE-2020-0663/index.md)","id":"CVE-2020-0663","markdown":"https://insights.sbomify.com/CVE-2020-0663/index.md","name":"CVE-2020-0663","record":{"aliases":["GHSA-r6w6-2q7f-ww58"],"analysis":{"component_type":"browser","fix_type":"patch","impacts":["privilege_escalation","data_read"],"network_reachable":"yes","non_default_config":false,"product_category":"Microsoft Edge browser","requires_auth":"none","summary":"Attackers can bypass cross-domain policies in Microsoft Edge to access and inject information across domains, leading to privilege escalation.","user_interaction":"required","vuln_class":"security_feature_bypass"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"microsoft","cpe":[{"product":"edge","vendor":"microsoft"}],"cvss":{"score":4.2,"severity":"medium","source":"nvd","vector":"CVSS:3.1/AV:N/AC:H/PR:N/UI:R/S:U/C:L/I:L/A:N","version":"3.1"},"cwes":[],"description":"An elevation of privilege vulnerability exists when Microsoft Edge does not properly enforce cross-domain policies, which could allow an attacker to access information from one domain and inject it into another domain.In a web-based attack scenario, an attacker could host a website that is used to attempt to exploit the vulnerability, aka 'Microsoft Edge Elevation of Privilege 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":"Security feature bypass in Microsoft Edge (EdgeHTML-based) on Windows 10 Version 1803 for 32-bit Systems","id":"CVE-2020-0663","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":"microsoft:edge","products":["microsoft:edge"],"type":"security_feature_bypass","year":"2020"},"n_packages":0,"n_references":1,"next":{"headline":"Active Directory Information Disclosure Vulnerability","id":"CVE-2020-0664"},"packages":[],"prev":{"headline":"Memory corruption in Windows","id":"CVE-2020-0662"},"products":["Microsoft Edge (EdgeHTML-based) on Windows 10 Version 1803 for 32-bit Systems","Microsoft Edge (EdgeHTML-based) on Windows 10 Version 1803 for ARM64-based Systems","Microsoft Edge (EdgeHTML-based) on Windows 10 Version 1803 for x64-based Systems","Microsoft Edge (EdgeHTML-based) on Windows 10 Version 1809 for 32-bit Systems","Microsoft Edge (EdgeHTML-based) on Windows 10 Version 1809 for ARM64-based Systems","Microsoft Edge (EdgeHTML-based) on Windows 10 Version 1809 for x64-based Systems","Microsoft Edge (EdgeHTML-based) on Windows 10 Version 1903 for 32-bit Systems","Microsoft Edge (EdgeHTML-based) on Windows 10 Version 1903 for ARM64-based Systems","Microsoft Edge (EdgeHTML-based) on Windows 10 Version 1903 for x64-based Systems","Microsoft Edge (EdgeHTML-based) on Windows 10 Version 1909 for 32-bit Systems","Microsoft Edge (EdgeHTML-based) on Windows 10 Version 1909 for ARM64-based Systems","Microsoft Edge (EdgeHTML-based) on Windows 10 Version 1909 for x64-based Systems","Microsoft Edge (EdgeHTML-based) on Windows Server 2019"],"published":"2020-02-11","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":"FIRST CVSS licence","name":"CVSS (FIRST)"}],"ssvc":{"automatable":null,"exploitation":null,"technical_impact":null},"state":"PUBLISHED","updated":"2024-08-04","vendors":["Microsoft"]},"summary":"Attackers can bypass cross-domain policies in Microsoft Edge to access and inject information across domains, leading to privilege escalation.","url":"https://insights.sbomify.com/CVE-2020-0663/"}
