## Technical details

The Delta Electronics DVP80ES300T PLC (versions 1.08 and prior) is vulnerable to an improper validation of array index (CWE-129). The flaw occurs when the device processes network-based inputs that are used as an index to an array without proper bounds checking. A remote, unauthenticated attacker can exploit this by sending a specially crafted packet to the device, leading to an out-of-bounds read or write. According to the CVSS metrics, the primary impact is a total loss of availability (Denial of Service), as the device may crash or enter an error state.

## Affected products

- Delta Electronics DVP80ES300T <= 1.08
