This vulnerability allows local attackers to escalate privileges on vulnerable installations of ABB MicroSCADA 9.3 with FP 1-2-3. An attacker must first obtain the ability to execute low-privileged code on the target system in order to exploit this vulnerability. The specific flaw exists within the configuration of the access controls for the installed product files. The installation procedure leaves critical files open to manipulation by any authenticated user. An attacker can leverage this vulnerability to escalate privileges to SYSTEM. Was ZDI-CAN-5097.
The product does not restrict or incorrectly restricts access to a resource from an unauthorized actor.

Access control involves the use of several protection mechanisms such as:
When any mechanism is not applied or otherwise fails, attackers can compromise the security of the product by gaining privileges, reading sensitive information, executing commands, evading detection, etc. There are two distinct behaviors that can introduce access control weaknesses:
