A heap-based buffer overflow vulnerability exists in the Programming Software Connection CurrDir functionality of AutomationDirect P3-550E 1.2.10.9. A specially crafted network packet can lead to denial of service. An attacker can send an unauthenticated packet to trigger these vulnerability.This CVE tracks the heap corruption that occurs at offset 0xb686c of version 1.2.10.9 of the P3-550E firmware, which occurs when a call to memset relies on an attacker-controlled length value and corrupts any trailing heap allocations.
