Vulnerability from variot - Updated: 2025-12-20 19:39

In AzeoTech DAQFactory release 20.7 (Build 2555), an Out-of-bounds Write vulnerability can be exploited by an attacker to cause the program to write data past the end of an allocated memory buffer. This can lead to arbitrary code execution or a system crash. This vulnerability allows remote attackers to execute arbitrary code on affected installations of AzeoTech DAQFactory. User interaction is required to exploit this vulnerability in that the target must visit a malicious page or open a malicious file.The specific flaw exists within the parsing of CTL files. An attacker can leverage this vulnerability to execute code in the context of the current process. AzeoTech DAQFactory is a data acquisition and monitoring software developed by AzeoTech, a US-based company, commonly used in industrial automation.
