CVE-2020-6780Network attack vector

Credential disclosure via brute-forceable MD5 password hashes

Published Jan 25, 2021 · Updated Sep 17, 2024

Password-hash weakness in Bosch FSM-2500 and FSM-5000 5.2 and earlier allows remote authenticated users to recover user passwords. The server database stores user passwords as MD5 hashes, permitting offline brute-force recovery after credential records are dumped. Administrative database privileges are required, and the bounded consequence is disclosure of other users' credentials and recoverable plaintext passwords.
