This could allow an attacker to dump and debug the firmware, including the manipulation of memory. Further actions could allow to inject public keys of custom created key pairs which are then signed by the LOGO! V8.3 Product CA.\n\nThe vulnerability is related to the specific hardware architecture of the LOGO! V8.3 BM. Siemens has released new hardware versions with the LOGO! V8.4 BM product family for several affected devices in which the vulnerability is fixed and the Product CA private key is rotated. Siemens is working on new hardware versions for the SIPLUS devices to address this issue further. See the chapter \"Additional Information\" below for more details.\n\nFor more information please also refer to the related product support article: \nhttps://support.industry.siemens.com/cs/ww/en/view/109826554/.",
