CVE-2024-39354

Code execution via DPA file stack overflow

Published Nov 11, 2024 · Updated Nov 11, 2024

Stack-based buffer overflow in Delta Electronics DIAScreen before 1.5.0 allows remote attackers to execute arbitrary code via a crafted DPA file. The CEtherIPTagItem DPA parser copies user-supplied data into a fixed-length stack buffer without validating its length. A user must visit a malicious page or open the file, and injected code runs in the context of the DIAScreen process.
