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-2023-1617 in the wild and no public exploit code.\n\nAffected product: B\u0026R VC4. 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-2023-1617/ (Markdown: https://insights.sbomify.com/CVE-2023-1617/index.md)","id":"CVE-2023-1617","markdown":"https://insights.sbomify.com/CVE-2023-1617/index.md","name":"CVE-2023-1617","record":{"aliases":["GHSA-493h-rq8m-6xjp"],"analysis":{"component_type":"ics_ot","fix_type":"upgrade","impacts":["security_bypass"],"network_reachable":"yes","non_default_config":false,"product_category":"Industrial Automation Visualization","requires_auth":"none","summary":"Unauthenticated attackers can bypass authentication in B\u0026R VC4 visualization modules, potentially accessing sensitive industrial control interfaces.","user_interaction":"not_required","vuln_class":"auth_bypass"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"ABB","cpe":[{"product":"vc4","vendor":"br-automation"}],"cvss":{"score":9.8,"severity":"critical","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-287","name":"Improper Authentication"}],"description":"Improper Authentication vulnerability in B\u0026R Industrial Automation B\u0026R VC4 (VNC-Server modules).  This vulnerability may allow an unauthenticated network-based attacker to bypass the authentication mechanism of the VC4 visualization on affected devices.
