WEINVIEW EBPro: Buffer overflow in UtilityManagerEx.exe allows code execution
Summary
WEINVIEW EBPro v6.10.01.510_20251022, the Windows engineering software for Weintek HMI panels, contains a buffer overflow in the component UtilityManagerEx.exe. According to the CVE record, a remote attacker can execute arbitrary code without authentication, which could lead to full control of the affected workstation. The sources do not explain which network input reaches the vulnerable component, so the real exposure depends on where EBPro is installed and reachable.
