{"cve":"CVE-2020-16231","nvd":{"published":"2022-05-19T18:15:08.487","modified":"2026-06-17T02:57:54.333","status":"Modified","description":"The affected Bachmann Electronic M-Base Controllers of version MSYS v1.06.14 and later use weak cryptography to protect device passwords. Affected controllers that are actively supported include MX207, MX213, MX220, MC206, MC212, MC220, and MH230 hardware controllers, and affected end-of-life controller include MC205, MC210, MH212, ME203, CS200, MP213, MP226, MPC240, MPC265, MPC270, MPC293, MPE270, and CPC210 hardware controllers. Security Level 0 is set at default from the manufacturer, which could allow an unauthenticated remote attacker to gain access to the password hashes. Security Level 4 is susceptible if an authenticated remote attacker or an unauthenticated person with physical access to the device reads and decrypts the password to conduct further attacks.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H","score":8.8},"cwes":["CWE-916"],"references":["https://www.cisa.gov/uscert/ics/advisories/icsa-21-026-02","https://www.cisa.gov/uscert/ics/advisories/icsa-21-026-02"],"products":["bachmann:cpc210_firmware","bachmann:cs200_firmware","bachmann:mc205_firmware","bachmann:mc206_firmware","bachmann:mc210_firmware","bachmann:mc212_firmware","bachmann:mc220_firmware","bachmann:me203_firmware","bachmann:mh212_firmware","bachmann:mh230_firmware","bachmann:mp213_firmware","bachmann:mp226_firmware","bachmann:mpc240_firmware","bachmann:mpc265_firmware","bachmann:mpc270_firmware","bachmann:mpc293_firmware","bachmann:mpe270_firmware","bachmann:mx207_firmware","bachmann:mx213_firmware","bachmann:mx220_firmware"],"source":"nvd","synced_at":"2026-10-19T21:31:59.322382750+00:00"},"epss":{"cve":"CVE-2020-16231","score":0.00882,"percentile":0.59181,"date":"2026-10-31"},"kev":null,"osv":[],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
