CVE-2025-59299

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 malicious DPA file. The DPA parser fails to validate user-controlled data before writing it past the end of an allocated data structure. Execution requires a user to open the crafted file or visit a malicious page, and the resulting code runs with the current DIAScreen process privileges.
