A vulnerability has been identified in LOGO! 8 BM (incl. SIPLUS variants) (All versions < V8.3), LOGO! Soft Comfort (All versions < V8.3). The encryption of program data for the affected devices uses a static key. An attacker could use this key to extract confidential information from protected program files.
The use of a hard-coded cryptographic key significantly increases the possibility that encrypted data may be recovered.
