A vulnerability has been identified in SICAM TOOLBOX II (All versions < V07.11). During establishment of a https connection to the TLS server of a managed device, the affected application doesn't check the extended key usage attribute of that device's certificate. This could allow an attacker to execute an on-path network (MitM) attack.
SEC Consult warns of adversary-in-the-middle attacks due to missing certificate validation in Siemens SICAM Toolbox II device communication; fixed in version 07.11.
