June 10, 2011
Siemens SIMATIC S7-1200 Programmable Logic Controller (PLC)
is prone to a security-bypass vulnerability and a
denial-of-service vulnerability.
Attackers can exploit the security-bypass issue to perform
unauthorized actions in the affected controller system by
sending arbitrary commands through replay attacks.
Attackers can exploit the denial-of-service issue by placing
the affected controller system in a stop/defect state.
