An attacker needs administrator access to exploit it, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2020-16231 in the wild and no public exploit code.\n\nAffected product: Bachmann Electronic, GmbH M1 Hardware Controller CPC210. 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-2020-16231/ (Markdown: https://insights.sbomify.com/CVE-2020-16231/index.md)","id":"CVE-2020-16231","markdown":"https://insights.sbomify.com/CVE-2020-16231/index.md","name":"CVE-2020-16231","record":{"aliases":["GHSA-hqr7-c67h-hjrc"],"analysis":{"component_type":"ics_ot","fix_type":"patch","impacts":["account_takeover","privilege_escalation"],"network_reachable":"yes","non_default_config":false,"product_category":"Bachmann M1 controller","requires_auth":"high_privilege","summary":"Weak password hashing in Bachmann M1 controllers allows attackers to recover credentials and gain unauthorized access to industrial control systems.","user_interaction":"not_required","vuln_class":"weak_cryptography"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"icscert","cpe":[{"product":"cpc210_firmware","vendor":"bachmann"},{"product":"cs200_firmware","vendor":"bachmann"},{"product":"mc205_firmware","vendor":"bachmann"},{"product":"mc206_firmware","vendor":"bachmann"},{"product":"mc210_firmware","vendor":"bachmann"},{"product":"mc212_firmware","vendor":"bachmann"},{"product":"mc220_firmware","vendor":"bachmann"},{"product":"me203_firmware","vendor":"bachmann"},{"product":"mh212_firmware","vendor":"bachmann"},{"product":"mh230_firmware","vendor":"bachmann"},{"product":"mp213_firmware","vendor":"bachmann"},{"product":"mp226_firmware","vendor":"bachmann"},{"product":"mpc240_firmware","vendor":"bachmann"},{"product":"mpc265_firmware","vendor":"bachmann"},{"product":"mpc270_firmware","vendor":"bachmann"},{"product":"mpc293_firmware","vendor":"bachmann"},{"product":"mpe270_firmware","vendor":"bachmann"},{"product":"mx207_firmware","vendor":"bachmann"},{"product":"mx213_firmware","vendor":"bachmann"},{"product":"mx220_firmware","vendor":"bachmann"}],"cvss":{"score":7.2,"severity":"high","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:H/UI:N/S:U/C:H/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-916","name":"Use of Password Hash With Insufficient Computational Effort"}],"description":"The affected Bachmann Electronic M-Base Controllers of version MSYS v1.06.14 and later use weak cryptography to protect device passwords.
