Core Server HMI Service (Coreservice.exe) in Scadatec Limited Procyon SCADA 1.06, and other versions before 1.14, allows remote attackers to cause a denial of service (crash) and possibly execute arbitrary code via a long password to the Telnet (TCP/23) port, which triggers an out-of-bounds read or write, leading to a stack-based buffer overflow.
The product performs operations on a memory buffer, but it reads from or writes to a memory location outside the buffer's intended boundary. This may result in read or write operations on unexpected memory locations that could be linked to other variables, data structures, or internal program data.
