Descriptions

A vulnerability has been identified in SIMATIC CP 343-1 (6GK7343-1EX30-0XE0) (All versions), SIMATIC CP 343-1 Lean (6GK7343-1CX10-0XE0) (All versions), SIPLUS NET CP 343-1 (6AG1343-1EX30-7XE0) (All versions), SIPLUS NET CP 343-1 Lean (6AG1343-1CX10-2XE0) (All versions). Affected products incorrectly validate TCP sequence numbers. This could allow an unauthenticated remote attacker to create a denial of service condition by injecting spoofed TCP RST packets.

Se ha identificado una vulnerabilidad en:
SIMATIC CP 343-1 (6GK7343-1EX30-0XE0) (todas las versiones),
SIMATIC CP 343-1 Lean (6GK7343-1CX10-0XE0) (todas las versiones),
