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-2018-16166 in the wild and no public exploit code.\n\nAffected product: JPCERT Coordination Center LogonTracer. 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-2018-16166/ (Markdown: https://insights.sbomify.com/CVE-2018-16166/index.md)","id":"CVE-2018-16166","markdown":"https://insights.sbomify.com/CVE-2018-16166/index.md","name":"CVE-2018-16166","record":{"aliases":["GHSA-264h-j8r7-hf4r"],"analysis":{"component_type":"web_application","fix_type":"upgrade","impacts":["data_read","denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"LogonTracer","requires_auth":"none","summary":"Remote attackers can exploit XML External Entity vulnerabilities in LogonTracer to read sensitive data or cause denial of service.","user_interaction":"required","vuln_class":"xxe"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"jpcert","cpe":[{"product":"logontracer","vendor":"jpcert"}],"cvss":{"score":8.8,"severity":"high","source":"nvd","vector":"CVSS:3.0/AV:N/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H","version":"3.0"},"cwes":[{"id":"CWE-611","name":"Improper Restriction of XML External Entity Reference"}],"description":"LogonTracer 1.2.0 and earlier allows remote attackers to conduct XML External Entity (XXE) attacks via unspecified vectors.","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"none_known"},"has_fix":false,"headline":"XML external entity in LogonTracer","id":"CVE-2018-16166","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"xxe","year":"2018"},"n_packages":0,"n_references":2,"next":{"headline":"Command injection in LogonTracer","id":"CVE-2018-16167"},"packages":[],"prev":{"headline":"Cross-site scripting in LogonTracer","id":"CVE-2018-16165"},"products":["LogonTracer"],"published":"2019-01-09","related":[{"cvss_score":9.8,"headline":"Command injection in LogonTracer","id":"CVE-2018-16167","kev_date_added":null,"published":"2019-01-09"},{"cvss_score":9.8,"headline":"Code injection in LogonTracer","id":"CVE-2018-16168","kev_date_added":null,"published":"2019-01-09"},{"cvss_score":8.7,"headline":"An OS command Injection issue exists in LogonTracer prior to v2.0.0.","id":"CVE-2026-33277","kev_date_added":null,"published":"2026-04-27"},{"cvss_score":6.1,"headline":"Cross-site scripting in LogonTracer","id":"CVE-2018-16165","kev_date_added":null,"published":"2019-01-09"},{"cvss_score":5.1,"headline":"Code injection in LogonTracer","id":"CVE-2026-33566","kev_date_added":null,"published":"2026-04-27"}],"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":["JPCERT Coordination Center"]},"summary":"Remote attackers can exploit XML External Entity vulnerabilities in LogonTracer to read sensitive data or cause denial of service.","url":"https://insights.sbomify.com/CVE-2018-16166/"}
