Details have emerged about multiple security vulnerabilities in two implementations of the Manufacturing Message Specification ( MMS ) protocol that, if successfully exploited, could have severe impacts in industrial environments. "The vulnerabilities could allow an attacker to crash an industrial device or in some cases, enable remote code execution," Claroty researchers Mashav Sapir and Vera Mens said in a new analysis. MMS is an OSI application layer messaging protocol that enables remote control and monitoring of industrial devices by exchanging supervisory control information in an application-agnostic manner. Specifically, it allows for communication between intelligent electronic devices ( IEDs ) and supervisory control and data acquisition (SCADA) systems or programmable logic controllers (PLCs). The five shortcomings identified by the operational technology security company impact MZ Automation's libIEC61850 library and Triangle MicroWorks' TMW IEC 61...
