Executive Summary

All versions of InSAT MasterSCADA BUK-TS have a security flaw in their MMadmServ web interface that allows attackers to inject operating system commands. This means that a malicious user can send specially crafted input to the vulnerable field, which the system then executes as commands on the underlying operating system.

This vulnerability can lead to remote code execution, allowing attackers to run arbitrary code on the affected system without any authentication.

Impact Analysis

This vulnerability can have severe impacts including unauthorized remote code execution on the affected system. An attacker exploiting this flaw could gain control over the system, potentially leading to data theft, system manipulation, disruption of services, or further attacks within the network.
