A vulnerability has been identified in LOGO! 8 BM (incl. SIPLUS variants) (All versions < V8.3). Affected devices load firmware updates without checking the authenticity. Furthermore the integrity of the unencrypted firmware is only verified by a non-cryptographic method. This could allow an attacker to manipulate a firmware update and flash it to the device.
The product does not sufficiently verify the origin or authenticity of data, in a way that causes it to accept invalid data.
