Technical details

An out-of-bounds write vulnerability (CWE-787) exists in AzeoTech DAQFactory release 20.7 (Build 2555) and prior. The flaw is triggered when the application improperly handles memory allocation while parsing specially crafted .ctl files. An attacker can exploit this by providing a malicious file to a user; upon opening, the program writes data past the end of an allocated buffer. This memory corruption can be leveraged to achieve arbitrary code execution in the context of the current process or cause a denial-of-service (system crash). The vulnerability is addressed in DAQFactory Release 21.1.
