Control Builder A
Monthly
Uncontrolled Search Path Element (DLL hijacking) in ABB Control Builder A and 800xA for Advant Master enables a local low-privileged attacker to achieve high-integrity code execution on industrial engineering workstations. Affected versions span Control Builder A through 1.4/4 and 800xA for Advant Master through 6.2.0-1, covering multiple release branches of ABB's flagship OT automation suite. No public exploit or CISA KEV listing is identified at time of analysis, limiting immediate mass-exploitation risk, though OT environments running these ICS platforms warrant targeted patching prioritization given integrity-impact severity.
