CVE-2018-7242 describes a critical vulnerability (CVSS 9.8) in Schneider Electric's Modicon Premium, Quantum, M340, and BMXNOR0200 controllers, affecting all versions of their communication modules. The flaw stems from the use of vulnerable hash algorithms for password encryption, making them susceptible to hash collision attacks. This allows an unauthenticated attacker to remotely compromise the system with high impact on confidentiality, integrity, and availability. Despite its severity, there is no evidence of active exploitation, public exploit code, or significant community discussion, and it is not listed in CISA's KEV catalog.
