Does this matter?

High impact if exploited, but EPSS currently rates exploitation as unlikely (1.92%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.

Description

Vulnerable hash algorithms exists in Schneider Electric's Modicon Premium, Modicon Quantum, Modicon M340, and BMXNOR0200 controllers in all versions of the communication modules. The algorithm used to encrypt the password is vulnerable to hash collision attacks.
