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-2016-8371 in the wild and no public exploit code.\n\nAffected product: Phoenix Contact ILC PLCs. 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-2016-8371/ (Markdown: https://insights.sbomify.com/CVE-2016-8371/index.md)","id":"CVE-2016-8371","markdown":"https://insights.sbomify.com/CVE-2016-8371/index.md","name":"CVE-2016-8371","record":{"aliases":["GHSA-vprp-wv7r-hv9r"],"analysis":{"component_type":"ics_ot","fix_type":"patch","impacts":["security_bypass"],"network_reachable":"yes","non_default_config":false,"product_category":"Phoenix Contact ILC PLC","requires_auth":"none","summary":"Attackers can access the web server of Phoenix Contact ILC PLCs without authentication, bypassing security controls even when enabled.","user_interaction":"not_required","vuln_class":"auth_bypass"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"icscert","cpe":[{"product":"ilc_plcs_firmware","vendor":"phoenixcontact"}],"cvss":{"score":7.3,"severity":"high","source":"nvd","vector":"CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:L/A:L","version":"3.0"},"cwes":[{"id":"CWE-287","name":"Improper Authentication"},{"id":"CWE-592","name":"DEPRECATED: Authentication Bypass Issues"}],"description":"The web server in Phoenix Contact ILC PLCs can be accessed without authenticating even if the authentication mechanism is enabled.","ecosystems":[],"exploits":{"exploitdb":1,"first_seen":"2018-10-12","github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[{"date":"2018-10-12","kind":"exploitdb","ref":"45590","stars":null,"title":"Phoenix Contact WebVisit 2985725 - Authentication Bypass"}],"tier":"poc_unverified"},"has_fix":null,"headline":"Auth bypass in Phoenix Contact ILC PLCs","id":"CVE-2016-8371","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"auth_bypass","year":"2016"},"n_packages":0,"n_references":3,"next":{"headline":"Weak cryptography in Moxa ioLogik E1200 Series before 3.12","id":"CVE-2016-8372"},"packages":[],"prev":{"headline":"Weak cryptography in Mitsubishi Electric MELSEC-Q Series Ethernet Interface Module","id":"CVE-2016-8370"},"products":["Phoenix Contact ILC PLCs"],"published":"2018-04-05","related":[{"cvss_score":7.3,"headline":"Hardcoded credentials in Phoenix Contact ILC PLCs","id":"CVE-2016-8366","kev_date_added":null,"published":"2018-04-05"},{"cvss_score":7.3,"headline":"Missing authorization in Phoenix Contact ILC PLCs","id":"CVE-2016-8380","kev_date_added":null,"published":"2018-04-05"}],"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)"},{"class":"attribution","licence":"GPL-2.0-or-later","name":"Exploit-DB"}],"ssvc":{"automatable":null,"exploitation":null,"technical_impact":null},"state":"PUBLISHED","updated":"2024-09-16","vendors":["Phoenix Contact"]},"summary":"Attackers can access the web server of Phoenix Contact ILC PLCs without authentication, bypassing security controls even when enabled.","url":"https://insights.sbomify.com/CVE-2016-8371/"}
