Technical details
A stack-based buffer overflow (CWE-121) exists in the Delta Electronics AS320T PLC firmware. The vulnerability is caused by a failure to validate the length of input strings used for file names before copying them into a fixed-size stack buffer. A remote, unauthenticated attacker can exploit this over the network by providing an oversized file name string. Successful exploitation can lead to arbitrary code execution or a denial-of-service (DoS) condition. The issue is addressed in firmware version 1.16.
