A serious vulnerability has been found in yet another computerized 
control system that runs some of the world's most critical 
infrastructure, this time in a product sold by a vendor known as the ABB 

According to researchers from C4 - a firm specializing in the security 
of so-called SCADA, or Supervisory Control And Data Acquisition, systems
- ABB's Process Communication Unit (PCU) 400 suffers from a critical 
buffer overflow bug.

"The vulnerability was exploited by C4 to verify it can be used for 
arbitrary code execution by an unauthorized attacker," researcher Idan 
Ofrat wrote in this advisory [1] published on Thursday. "In addition, an 
attacker can use his control over the FEP server to insert a generic 
electric grid order to cause harm to the grid."

The vulnerable software controls critical national infrastructure, 
including electrical grids. The vulnerability affects versions 4.4, 4.5, 
and 4.6, and possibly others, the C4 advisory warns.

ABB has issued a patch for the bug.
