Technical details

A stack-based buffer overflow (CWE-121) exists in Delta Electronics ASDA-Soft versions 7.2.2.0 and prior. The vulnerability is triggered when the application processes a malformed file or input, leading to an out-of-bounds write (CWE-787) on the stack. While the attack vector is local, it requires user interaction (UI:R), such as opening a malicious project file. Successful exploitation can result in arbitrary code execution with the privileges of the application or a complete application crash. Users are advised to update to version 7.2.6.0 or later to mitigate this risk.
