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-2017-2684 in the wild and no public exploit code.\n\nAffected product: SIMATIC Logon All versions \u003c V1.5 SP3 Update 2. 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-2017-2684/ (Markdown: https://insights.sbomify.com/CVE-2017-2684/index.md)","id":"CVE-2017-2684","markdown":"https://insights.sbomify.com/CVE-2017-2684/index.md","name":"CVE-2017-2684","record":{"aliases":["GHSA-h5v3-4rh5-mj9g"],"analysis":{"component_type":"server_software","fix_type":"upgrade","impacts":["security_bypass"],"network_reachable":"yes","non_default_config":false,"product_category":"Siemens SIMATIC Logon","requires_auth":"none","summary":"An attacker with valid username knowledge and access can bypass application-level authentication in Siemens SIMATIC Logon.","user_interaction":"not_required","vuln_class":"auth_bypass"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"siemens","cpe":[{"product":"simatic_logon","vendor":"siemens"}],"cvss":{"score":9,"severity":"critical","source":"nvd","vector":"CVSS:3.0/AV:N/AC:H/PR:N/UI:N/S:C/C:H/I:H/A:H","version":"3.0"},"cwes":[{"id":"CWE-592","name":"DEPRECATED: Authentication Bypass Issues"}],"description":"Siemens SIMATIC Logon prior to V1.5 SP3 Update 2 could allow an attacker with knowledge of a valid user name, and physical or network access to the affected system, to bypass the application-level authentication.","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":"Auth bypass in SIMATIC Logon All versions \u003c V1.5 SP3 Update 2","id":"CVE-2017-2684","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"auth_bypass","year":"2017"},"n_packages":0,"n_references":2,"next":{"headline":"Weak cryptography in SINUMERIK Integrate Operate Clients 2.x and 3.x","id":"CVE-2017-2685"},"packages":[],"prev":{"headline":"Cross-site scripting in RUGGEDCOM NMS All versions \u003c V2.1 (Windows and Linux)","id":"CVE-2017-2683"},"products":["SIMATIC Logon All versions \u003c V1.5 SP3 Update 2"],"published":"2017-02-22","related":[{"cvss_score":7.5,"headline":"Denial of service in SIMATIC Logon All versions before V1.6","id":"CVE-2017-9938","kev_date_added":null,"published":"2017-08-08"}],"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":["n/a"]},"summary":"An attacker with valid username knowledge and access can bypass application-level authentication in Siemens SIMATIC Logon.","url":"https://insights.sbomify.com/CVE-2017-2684/"}
