An attacker can exploit it over the internet without logging in, and only if a user opens a file or follows a link."},"fix_prompt":"Check this codebase for CVE-2018-8414 and fix it if it is affected.\n\nWhat it is: CVE-2018-8414 is a high-severity path traversal vulnerability in Microsoft Windows 10, published on 15 Aug 2018. An attacker can exploit it over the internet without logging in, and only if a user opens a file or follows a link.\nExploitation: Yes. Attackers have exploited CVE-2018-8414 in the wild since at least 25 Mar 2022.\n\nAffected product: Microsoft Windows 10. 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-2018-8414/ (Markdown: https://insights.sbomify.com/CVE-2018-8414/index.md)","id":"CVE-2018-8414","markdown":"https://insights.sbomify.com/CVE-2018-8414/index.md","name":"CVE-2018-8414","record":{"aliases":["GHSA-xg99-mpwj-gf2c"],"analysis":{"component_type":"operating_system","fix_type":"patch","impacts":["code_execution"],"network_reachable":"yes","non_default_config":false,"product_category":"Windows Shell","requires_auth":"none","summary":"Attackers can execute arbitrary code by exploiting improper file path validation in the Windows Shell.","user_interaction":"required","vuln_class":"path_traversal"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"microsoft","cpe":[{"product":"windows_10_1703","vendor":"microsoft"},{"product":"windows_10_1709","vendor":"microsoft"},{"product":"windows_10_1803","vendor":"microsoft"},{"product":"windows_server_1709","vendor":"microsoft"},{"product":"windows_server_1803","vendor":"microsoft"}],"cvss":{"score":8.8,"severity":"high","source":"cisa-adp","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-20","name":"Improper Input Validation"}],"description":"A remote code execution vulnerability exists when the Windows Shell does not properly validate file paths, aka \"Windows Shell Remote Code Execution Vulnerability.\" This affects Windows 10 Servers, Windows 10.","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":"2018-08-24","github_poc":1,"max_poc_stars":21,"metasploit":0,"nuclei":0,"refs":[{"date":"2018-08-24T18:09:29Z","kind":"github_poc","ref":"https://github.com/whereisr0da/CVE-2018-8414-POC","stars":21,"title":"Simple poc of CVE-2018-8414 Windows Package Setting RCE Vulnerability"}],"tier":"exploited"},"has_fix":null,"headline":"Microsoft Windows Shell Remote Code Execution","id":"CVE-2018-8414","indexable":true,"kev":{"dateAdded":"2022-03-25","dueDate":"2022-04-15","knownRansomwareCampaignUse":"Unknown","product":"Windows","requiredAction":"Apply updates per vendor instructions.","vendorProject":"Microsoft","vulnerabilityName":"Microsoft Windows Shell Remote Code Execution Vulnerability"},"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"path_traversal","year":"2018"},"n_packages":0,"n_references":3,"next":{"headline":"Code injection in PowerShell Core","id":"CVE-2018-8415"},"packages":[],"prev":{"headline":"Code injection in Windows 10","id":"CVE-2018-8413"},"products":["Windows 10","Windows 10 Servers"],"published":"2018-08-15","related":[{"cvss_score":7.8,"headline":"Microsoft Windows AppX Deployment Server Privilege Escalation","id":"CVE-2019-1253","kev_date_added":"2022-03-15","published":"2019-09-11"},{"cvss_score":7.8,"headline":"Microsoft Windows AppX Deployment Service (AppXSVC) Privilege Escalation","id":"CVE-2019-1129","kev_date_added":"2022-03-15","published":"2019-07-29"},{"cvss_score":7.8,"headline":"Microsoft Windows AppX Deployment Service (AppXSVC) Privilege Escalation","id":"CVE-2019-0841","kev_date_added":"2022-03-15","published":"2019-04-09"}],"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":"open","licence":"CC0 1.0","name":"CISA KEV"},{"class":"attribution","licence":"CWE Terms of Use","name":"CWE (MITRE)"},{"class":"attribution","licence":"FIRST CVSS licence","name":"CVSS (FIRST)"},{"class":"open","licence":"CC0","name":"PoC-in-GitHub"}],"ssvc":{"automatable":"no","exploitation":"active","technical_impact":"total"},"state":"PUBLISHED","updated":"2025-10-21","vendors":["Microsoft"]},"summary":"Attackers can execute arbitrary code by exploiting improper file path validation in the Windows Shell.","url":"https://insights.sbomify.com/CVE-2018-8414/"}
