Affected devices do not properly limit the bandwidth for incoming network packets over their local USB port. This could allow an attacker with physical access to send specially crafted packets with high bandwidth to the affected devices thus forcing them to exhaust their memory and stop responding to any network traffic via the local USB port. Affected devices reset themselves automatically after a successful attack. The protection function is not affected of this vulnerability.
A vulnerability exists in various SIPROTEC 5 devices, specifically in the 6MD84, 6MD85, 6MD86, 6MD89, 6MU85, 7KE85, 7SA82, 7SA86, 7SA87, 7SD82, 7SD86, 7SD87, 7SJ81, 7SJ82, 7SJ85, 7SJ86, 7SK82, 7SK85, 7SL82, 7SL86, 7SL87, 7SS85, 7ST85, 7ST86, 7SX82, 7SX85, 7SY82, 7UM85, 7UT82, 7UT85, 7UT86, 7UT87, 7VE85, 7VK87, 7VU85, and Compact 7SX800 (CP050) product lines. The vulnerability affects all versions prior to V10.0, with specific conditions for some versions. The issue arises because these devices do not adequately restrict the bandwidth of incoming network packets through the local USB port. This flaw could enable an attacker with physical access to send high-bandwidth packets, causing the device to deplete its memory and cease communication over the USB port. After such an attack, the devices automatically reset, although their protective functions remain intact.
Siemens has released version V10.0 for the affected products and recommends updating to this version or later. For SIPROTEC 5 Compact 7SX800 (CP050), all versions prior to V10.0 are affected. General security guidelines can be found on the Siemens Grid Security website.
