CVE-2019-5620: ABB MicroSCADA wserver.exe Remote Code Execution

ABB MicroSCADA wserver.exe Remote Code Execution

Description

This module exploits a remote stack buffer overflow vulnerability in ABB MicroSCADA. The issue is due to the handling of unauthenticated EXECUTE operations on the wserver.exe component, which allows arbitrary commands. The component is disabled by default, but required when a project uses the SCIL function WORKSTATION_CALL. This module has been tested successfully on ABB MicroSCADA Pro SYS600 9.3 on Windows XP SP3 and Windows 7 SP1.

Module Options

To display the available options, load the module within the Metasploit console and run the commands ‘show options’ or 'show advanced’:

msf > use exploit/windows/scada/abb_wserver_exec
msf exploit(abb_wserver_exec) > show targets
    ...targets...
msf exploit(abb_wserver_exec) > set TARGET < target-id >
msf exploit(abb_wserver_exec) > show options
    ...show and set options...
msf exploit(abb_wserver_exec) > exploit

Time is precious, so I don’t want to do something manually that I can automate. Leveraging the Metasploit Framework when automating any task keeps us from having to re-create the wheel as we can use the existing libraries and focus our efforts where it matters.
