Freewill Solutions IFIS new trading web application version 20.01.01.04 is vulnerable to unauthenticated remote code execution. Successful exploitation of this vulnerability allows an attacker to run arbitrary shell commands on the affected host.
Freewill Solutions IFIS new trading web application passes a user controlled variable directly to a shell_exec function call on a specific report page. To exploit the vulnerability, an attacker can add shell meta characters to the user controlled variable so that the application executes attacker specified commands.
An attacker with access to the applications web interface can execute code on the remote host. This level of access allows for complete compromise of the affected machine.
The CERT/CC is currently unaware of a practical solution to this problem.
Thanks to Sameer Mohite (Mandiant) for reporting the vulnerability.
