Unitronics

Unitronics manufactures industrial automation controllers and their associated development platforms, including products such as UniLogic and Visilogic that are deployed in critical operational technology environments. Vulnerabilities affecting this vendor skew strongly toward critical severity and recur through weakness classes including path traversal, buffer-boundary violations, hard-coded credentials, and embedded malicious code—flaws that reflect both the legacy security posture of embedded firmware and the memory constraints typical of industrial control devices. A moderate share of the vendor's disclosures has attracted confirmed in-the-wild exploitation; defenders should prioritize inventory and assessment of affected controller models and development tooling, particularly those exposed to untrusted networks. Live severity, exploitation activity, and exposure counts are shown alongside this summary.
