A vulnerability has been identified in LOGO! 8 BM (incl. SIPLUS variants) (All versions < V8.3). The implemented encryption for communication with affected devices is prone to replay attacks due to the usage of a static key. An attacker could change the password or change the configuration on any affected device if using prepared messages that were generated for another device.
