Code execution via unchecked DPA length copy
Published Aug 6, 2024 · Updated Aug 6, 2024
Stack-based buffer overflow in Delta Electronics DIAScreen before 1.4.2 allows remote attackers to execute code via a crafted DPA file. The DPA parser copies user-supplied data into a fixed-length stack buffer without first validating its length. Exploitation requires a targeted user to open the malicious file or visit attacker-controlled content, and resulting code runs in the current process.

Exploitability
Present is not the same as exploitable
Compare your product and version with the public record. A matching version still requires validation against your environment.
Is a vulnerable build present?
Compare these published version ranges with your installed build and any vendor patches.
