An attacker can exploit it over the internet without logging in, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2017-11767 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- Microsoft.ChakraCore (NuGet): affected all versions; fixed in 1.6.2\n- Microsoft.ChakraCore (NuGet): affected all versions; fixed in 1.6.2\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-2017-11767/ (Markdown: https://insights.sbomify.com/CVE-2017-11767/index.md)","id":"CVE-2017-11767","markdown":"https://insights.sbomify.com/CVE-2017-11767/index.md","name":"CVE-2017-11767","record":{"aliases":["GHSA-c79v-2rjq-965m"],"analysis":{"component_type":"library","fix_type":"patch","impacts":["code_execution"],"network_reachable":"yes","non_default_config":false,"product_category":"ChakraCore JavaScript engine","requires_auth":"none","summary":"An attacker can execute arbitrary code with current user privileges due to memory corruption in the ChakraCore scripting engine.","user_interaction":"not_required","vuln_class":"memory_corruption"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"microsoft","cpe":[{"product":"chakracore","vendor":"microsoft"}],"cvss":{"score":9.8,"severity":"critical","source":"nvd","vector":"CVSS:3.0/AV:N/AC:L/PR:N/UI:N/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 allows an attacker to gain the same user rights as the current user, due to the way that the ChakraCore scripting engine handles objects in memory, aka \"Scripting Engine Memory Corruption Vulnerability\".","ecosystems":["NuGet"],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"none_known"},"has_fix":true,"headline":"ChakraCore vulnerable to privilege escalation","id":"CVE-2017-11767","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":"NuGet","product":"microsoft:chakracore","products":["microsoft:chakracore"],"type":"memory_corruption","year":"2017"},"n_packages":2,"n_references":3,"next":{"headline":"Information disclosure in Windows Media Player","id":"CVE-2017-11768"},"packages":[{"ecosystem":"NuGet","fixed":["1.6.2"],"introduced":["0"],"last_affected":[],"package":"Microsoft.ChakraCore","purl":null,"source":"GHSA-c79v-2rjq-965m"},{"ecosystem":"NuGet","fixed":["1.6.2"],"introduced":["0"],"last_affected":[],"package":"Microsoft.ChakraCore","purl":"pkg:nuget/Microsoft.ChakraCore","source":"GHSA-c79v-2rjq-965m"}],"prev":{"headline":"Memory corruption in Microsoft Edge","id":"CVE-2017-11766"},"products":["ChakraCore"],"published":"2017-11-02","related":[{"cvss_score":7.5,"headline":"ChakraCore Scripting Engine Type Confusion","id":"CVE-2018-8298","kev_date_added":"2022-03-03","published":"2018-07-11"},{"cvss_score":4.2,"headline":"Microsoft Edge and Internet Explorer Memory Corruption","id":"CVE-2020-0878","kev_date_added":"2021-11-03","published":"2020-09-11"},{"cvss_score":9.8,"headline":"ChakraCore RCE Vulnerability","id":"CVE-2018-8500","kev_date_added":null,"published":"2018-10-10"},{"cvss_score":9.8,"headline":"ChakraCore RCE Vulnerability","id":"CVE-2017-8658","kev_date_added":null,"published":"2017-08-11"},{"cvss_score":8.8,"headline":"Scripting Engine Memory Corruption Vulnerability","id":"CVE-2020-1555","kev_date_added":null,"published":"2020-08-17"},{"cvss_score":8.1,"headline":"ChakraCore RCE Vulnerability","id":"CVE-2020-1073","kev_date_added":null,"published":"2020-06-09"}],"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)"}],"ssvc":{"automatable":null,"exploitation":null,"technical_impact":null},"state":"PUBLISHED","updated":"2024-09-16","vendors":["Microsoft Corporation"]},"summary":"An attacker can execute arbitrary code with current user privileges due to memory corruption in the ChakraCore scripting engine.","url":"https://insights.sbomify.com/CVE-2017-11767/"}
