CVE-2025-59300

Code execution via DPA parser out-of-bounds write

Published Oct 3, 2025 · Updated Oct 3, 2025

Out-of-bounds write in Delta Electronics DIAScreen before 1.6.1 allows remote attackers to execute code via a crafted DPA file. The DPA file parser fails to validate user-supplied data before writing past the end of an allocated data structure. Exploitation requires the target to visit a malicious page or open a malicious file, and resulting code runs in the current process.
