This attack could pose a serious security threat. You should take immediate action to stop any damage or prevent further damage from happening.
This signature detects attempt of leveraging a remote code execution vulnerability in ABB MicroSCADA which could result in executing arbitrary code in the context of the affected process.
ABB MicroSCADA is a system for real-time monitoring and control of primary and secondary equipment.
ABB MicroSCADA is prone to a remote code-execution vulnerability because it fails to properly sanitize user-supplied input before using it in a 'CreateProcessA()' call. Specifically, this issue that exists in the 'wserver.exe' program. This issue can be exploited to execute remote code by supplying an UNC path to an attacker-controlled binary.
Attackers can exploit this issue to execute arbitrary code in the context of the affected process.
