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-2018-16189 in the wild and no public exploit code.\n\nAffected product: Micco Self-Extracting Archives created by UNLHA32.DLL. 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-2018-16189/ (Markdown: https://insights.sbomify.com/CVE-2018-16189/index.md)","id":"CVE-2018-16189","markdown":"https://insights.sbomify.com/CVE-2018-16189/index.md","name":"CVE-2018-16189","record":{"aliases":["GHSA-rcgr-7x99-fxwp"],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["privilege_escalation","code_execution"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"UNLHA32.DLL archive library","requires_auth":"none","summary":"Attackers can execute arbitrary code and gain privileges by placing a malicious DLL in a directory searched by UNLHA32.DLL during archive extraction.","user_interaction":"required","vuln_class":"privilege_escalation"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"jpcert","cpe":[{"product":"unlha32.dll","vendor":"micco"}],"cvss":{"score":7.8,"severity":"high","source":"nvd","vector":"CVSS:3.0/AV:L/AC:L/PR:N/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 Self-Extracting Archives created by UNLHA32.DLL prior to Ver 3.00 allows an attacker 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":"Privilege escalation in Self-Extracting Archives created by UNLHA32.DLL","id":"CVE-2018-16189","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"privilege_escalation","year":"2018"},"n_packages":0,"n_references":2,"next":{"headline":"Other in UNARJ32.DLL for Win32, LHMelting for Win32, and LMLzh32.DLL","id":"CVE-2018-16190"},"packages":[],"prev":{"headline":"SQL injection in RICOH Interactive Whiteboard","id":"CVE-2018-16188"},"products":["Self-Extracting Archives created by UNLHA32.DLL"],"published":"2019-02-13","related":[{"cvss_score":7.8,"headline":"Other in The installer of UNLHA32.DLL","id":"CVE-2019-5911","kev_date_added":null,"published":"2019-02-13"}],"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":["Micco"]},"summary":"Attackers can execute arbitrary code and gain privileges by placing a malicious DLL in a directory searched by UNLHA32.DLL during archive extraction.","url":"https://insights.sbomify.com/CVE-2018-16189/"}
