CVE-2023-43823Network attack vector

Code execution via wTTitleLen stack buffer overflow

Published Jan 18, 2024 · Updated Jun 2, 2025

Stack-based buffer overflow in Delta Electronics DOPSoft 2.00.00.00 through 2.00.07.04 allows remote attackers to execute arbitrary code. The DPS file parser uses the untrusted wTTitleLen field without adequately bounding a stack-buffer operation, allowing crafted title data to overwrite stack memory. Exploitation requires a user to open a specially crafted DPS project file, after which attacker-controlled code runs in the application context.
