It can only be exploited from the same machine or local network, and only if a user opens a file or follows a link.\nExploitation: There is no known exploitation of CVE-2017-2157 in the wild and no public exploit code.\n\nAffected product: Japan Agency for Local Authority Information Systems Installer for The Public Certification Service for Individuals \"The JPKI user's software (for Windows 7 and later)\". 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-2017-2157/ (Markdown: https://insights.sbomify.com/CVE-2017-2157/index.md)","id":"CVE-2017-2157","markdown":"https://insights.sbomify.com/CVE-2017-2157/index.md","name":"CVE-2017-2157","record":{"aliases":["GHSA-x8rm-c2pf-m49v"],"analysis":{"component_type":"desktop_application","fix_type":"upgrade","impacts":["privilege_escalation"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"JPKI user software","requires_auth":"low_privilege","summary":"Remote attackers can gain privileges via a Trojan horse DLL due to an untrusted search path in the JPKI user software installer.","user_interaction":"required","vuln_class":"other"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"jpcert","cpe":[{"product":"the_public_certification_service_for_individuals","vendor":"jpki"}],"cvss":{"score":7.3,"severity":"high","source":"nvd","vector":"CVSS:3.0/AV:L/AC:L/PR:L/UI:R/S:U/C:H/I:H/A:H","version":"3.0"},"cwes":[{"id":"CWE-426","name":"Untrusted Search Path"}],"description":"Untrusted search path vulnerability in installers for The Public Certification Service for Individuals \"The JPKI user's software (for Windows 7 and later)\" Ver3.1 and earlier, The Public Certification Service for Individuals \"The JPKI user's software (for Windows Vista)\", The Public Certification Service for Individuals \"The JPKI user's software\" Ver2.6 and earlier that were available until April 27, 2017 allows remote attackers to gain privileges via a Trojan horse DLL in an unspecified directory.","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":"Other in Installer for The Public Certification Service for Individuals \"The JPKI user's software (for Windows 7 and later)\"","id":"CVE-2017-2157","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"other","year":"2017"},"n_packages":0,"n_references":2,"next":{"headline":"Path traversal in Lhaplus","id":"CVE-2017-2158"},"packages":[],"prev":{"headline":"Path traversal in Vivaldi installer for Windows","id":"CVE-2017-2156"},"products":["Installer for The Public Certification Service for Individuals \"The JPKI user's software (for Windows 7 and later)\"","Installer for The Public Certification Service for Individuals \"The JPKI user's software (for Windows Vista)\"","Installer for The Public Certification Service for Individuals \"The JPKI user's software\""],"published":"2017-05-12","related":[{"cvss_score":7.8,"headline":"Privilege escalation in The Public Certification Service for Individuals \"The JPKI user's software (for Windows 7 and later)\"","id":"CVE-2016-4902","kev_date_added":null,"published":"2017-06-09"}],"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":"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":"2024-08-05","vendors":["Japan Agency for Local Authority Information Systems"]},"summary":"Remote attackers can gain privileges via a Trojan horse DLL due to an untrusted search path in the JPKI user software installer.","url":"https://insights.sbomify.com/CVE-2017-2157/"}
