An attacker can exploit it over the internet without logging in, and only if a user opens a file or follows a link.\nExploitation: It is not confirmed as exploited in the wild, but public exploit code for CVE-2016-7203 exists.\n\nAffected packages and fixed versions:\n- Microsoft.ChakraCore (NuGet): affected all versions; fixed in 1.2.2\n- Microsoft.ChakraCore (NuGet): affected all versions; fixed in 1.2.2\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-2016-7203/ (Markdown: https://insights.sbomify.com/CVE-2016-7203/index.md)","id":"CVE-2016-7203","markdown":"https://insights.sbomify.com/CVE-2016-7203/index.md","name":"CVE-2016-7203","record":{"aliases":["GHSA-wcvc-rhfj-997g"],"analysis":{"component_type":"browser","fix_type":"patch","impacts":["code_execution","denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"Microsoft Edge","requires_auth":"none","summary":"Remote attackers can execute arbitrary code or cause denial of service via a crafted website exploiting memory corruption in the Chakra engine.","user_interaction":"required","vuln_class":"memory_corruption"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"microsoft","cpe":[{"product":"edge","vendor":"microsoft"}],"cvss":{"score":7.5,"severity":"high","source":"nvd","vector":"CVSS:3.0/AV:N/AC:H/PR:N/UI:R/S:U/C:H/I:H/A:H","version":"3.0"},"cwes":[{"id":"CWE-119","name":"Improper Restriction of Operations within the Bounds of a Memory Buffer"}],"description":"The Chakra JavaScript scripting engine in Microsoft Edge allows remote attackers to execute arbitrary code or cause a denial of service (memory corruption) via a crafted web site, aka \"Scripting Engine Memory Corruption Vulnerability,\" a different vulnerability than CVE-2016-7200, CVE-2016-7201, CVE-2016-7202, CVE-2016-7208, CVE-2016-7240, CVE-2016-7242, and CVE-2016-7243.","ecosystems":["NuGet"],"exploits":{"exploitdb":1,"first_seen":"2016-11-18","github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[{"date":"2016-11-18","kind":"exploitdb","ref":"40787","stars":null,"title":"Microsoft Edge - 'Array.splice' Heap Overflow"}],"tier":"weaponised"},"has_fix":true,"headline":"ChakraCore RCE Vulnerability","id":"CVE-2016-7203","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":"NuGet","product":"microsoft:edge","products":["microsoft:edge"],"type":"memory_corruption","year":"2016"},"n_packages":2,"n_references":4,"next":{"headline":"Information disclosure in n/a","id":"CVE-2016-7204"},"packages":[{"ecosystem":"NuGet","fixed":["1.2.2"],"introduced":["0"],"last_affected":[],"package":"Microsoft.ChakraCore","purl":null,"source":"GHSA-wcvc-rhfj-997g"},{"ecosystem":"NuGet","fixed":["1.2.2"],"introduced":["0"],"last_affected":[],"package":"Microsoft.ChakraCore","purl":"pkg:nuget/Microsoft.ChakraCore","source":"GHSA-wcvc-rhfj-997g"}],"prev":{"headline":"ChakraCore RCE Vulnerability","id":"CVE-2016-7202"},"products":["n/a"],"published":"2016-11-10","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":"CC BY 4.0","name":"GitHub Advisory Database","prefix":"GHSA"},{"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)"},{"class":"attribution","licence":"GPL-2.0-or-later","name":"Exploit-DB"}],"ssvc":{"automatable":null,"exploitation":null,"technical_impact":null},"state":"PUBLISHED","updated":"2024-08-06","vendors":["n/a"]},"summary":"Remote attackers can execute arbitrary code or cause denial of service via a crafted website exploiting memory corruption in the Chakra engine.","url":"https://insights.sbomify.com/CVE-2016-7203/"}
