PLANET IGS-5225-8P2T4S industrial managed switch V1 and V2 firmware versions before 1.2412b260707 and 2.2412b260519 use MD5-based password hashing, a cryptographic algorithm with known weaknesses. An attacker who obtains the device configuration file can recover the privileged-mode access password.
