The ABB IDAL FTP server is vulnerable to a buffer overflow when a long string is sent by an authenticated attacker. This overflow is handled, but terminates the process. An authenticated attacker can send a FTP command string of 472 bytes or more to overflow a buffer, causing an exception that terminates the server.
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.
