Unspecified Vulnerability in Siemens LOGO! BM (Base Module) Devices

Siemens LOGO! BM (Base Module) devices are used for basic small-scale automation tasks. An unspecified vulnerability exists in the Siemens LOGO! BM (Base Module) device due to the susceptibility of the affected device to electromagnetic fault injection. An attacker could exploit the vulnerability to allow injection of a public key for a custom created key pair, which is then signed by the product CA. Generating a custom certificate allows communication and emulation with any device of the same version.
