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-2017-11843 in the wild and no public exploit code.\n\nAffected product: Microsoft Chakracore. 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-2017-11843/ (Markdown: https://insights.sbomify.com/CVE-2017-11843/index.md)","id":"CVE-2017-11843","markdown":"https://insights.sbomify.com/CVE-2017-11843/index.md","name":"CVE-2017-11843","record":{"aliases":["GHSA-jx2p-r863-cg3f"],"analysis":{"component_type":"browser","fix_type":"patch","impacts":["code_execution"],"network_reachable":"yes","non_default_config":false,"product_category":"Microsoft Edge/IE","requires_auth":"none","summary":"Memory corruption in the scripting engine allows attackers to execute arbitrary code with current user privileges via malicious web content.","user_interaction":"required","vuln_class":"memory_corruption"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"microsoft","cpe":[{"product":"chakracore","vendor":"microsoft"},{"product":"edge","vendor":"microsoft"},{"product":"internet_explorer","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":"ChakraCore and Internet Explorer in Microsoft Windows 7 SP1, Windows Server 2008 and R2 SP1, Windows 8.1 and Windows RT 8.1, Windows Server 2012 R2, and Microsoft Edge and Internet Explorer in Windows 10 Gold, 1511, 1607, 1703, 1709, Windows Server 2016 and Windows Server, version 1709 allows an attacker to gain the same user rights as the current user, due to how the scripting engine handles objects in memory, aka \"Scripting Engine Memory Corruption Vulnerability\".
