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-2023-0052 in the wild and no public exploit code.\n\nAffected product: SAUTER Controls Nova 106 (EYK300F001) BACnet communication card. 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-2023-0052/ (Markdown: https://insights.sbomify.com/CVE-2023-0052/index.md)","id":"CVE-2023-0052","markdown":"https://insights.sbomify.com/CVE-2023-0052/index.md","name":"CVE-2023-0052","record":{"aliases":["GHSA-fr44-f297-ppg9"],"analysis":{"component_type":"ics_ot","fix_type":"patch","impacts":["code_execution","data_modify"],"network_reachable":"yes","non_default_config":false,"product_category":"SAUTER Controls Nova","requires_auth":"none","summary":"Unauthorized users can execute commands and modify configurations on SAUTER Controls Nova devices due to missing authentication for critical functions.","user_interaction":"not_required","vuln_class":"missing_authorization"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"icscert","cpe":[{"product":"modunet300_ey-am300f001_firmware","vendor":"sauter-controls"},{"product":"modunet300_ey-am300f002_firmware","vendor":"sauter-controls"},{"product":"nova_106_eyk300f001_firmware","vendor":"sauter-controls"},{"product":"nova_220_eyk220f001_firmware","vendor":"sauter-controls"},{"product":"nova_230_eyk230f001_firmware","vendor":"sauter-controls"}],"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-306","name":"Missing Authentication for Critical Functionality"}],"description":"SAUTER Controls Nova 200–220 Series with firmware version 3.3-006 and prior and BACnetstac version 4.2.1 and prior allows the execution of commands without credentials.
