## Technical details

An uncontrolled search path element vulnerability (CWE-427) exists in ABB Control Builder A and 800xA for Advant Master. The vulnerability stems from the application searching for critical resources or libraries in directories that may be writable by a local user. An attacker with low privileges could place a malicious executable or library (such as a DLL) in the search path. Exploitation requires user interaction, typically involving a legitimate user executing the application while the malicious file is present in a high-priority search directory. Successful exploitation allows the attacker to execute code with the privileges of the application, potentially leading to unauthorized system modifications.
