Siemens FactoryLink 8 CSService Logging Path Param Buffer Overflow



This module exploits a vulnerability found on Siemens FactoryLink 8. The vulnerability occurs when CSService.exe processes a CSMSG_ListFiles_REQ message, the user-supplied path first gets converted to ANSI format (CodePage 0), and then gets handled by a logging routine where proper bounds checking is not done, therefore causing a stack-based buffer overflow, and results arbitrary code execution.

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/factorylink_csservice
msf exploit(factorylink_csservice) > show targets
msf exploit(factorylink_csservice) > set TARGET < target-id >
msf exploit(factorylink_csservice) > show options
    ...show and set options...
msf exploit(factorylink_csservice) > 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.
