Microsoft security researchers have discovered over two dozen critical remote code execution vulnerabilities in Internet of Things devices and Operational Technology industrial systems.

Threat actors can exploit them to trigger system crashes and execute malicious code remotely on vulnerable IoT and OT systems.

"Our research shows that memory allocation implementations written throughout the years as part of IoT devices and embedded software have not incorporated proper input validations," the Microsoft Security Response Center team said.

"Without these input validations, an attacker could exploit the memory allocation function to perform a heap overflow, resulting in execution of malicious code on a target device."

Vulnerable IoT and OT devices impacted by the BadAlloc vulnerabilities can be found on consumer, medical, and industrial networks.

Minimize network exposure for all control system devices and/or systems, and ensure that they are not accessible from the Internet.
