Technical details

A type confusion vulnerability (CWE-843) exists in AzeoTech DAQFactory release 20.7 (Build 2555) and earlier. The flaw occurs during the parsing of .ctl files when the application accesses a resource using an incompatible type, leading to memory corruption. An attacker can exploit this by providing a malicious .ctl file that, when opened by a user, triggers the vulnerability. This can result in arbitrary code execution in the context of the current process. The issue is resolved in DAQFactory Release 21.1.
