iniNet Solutions GmbH SCADA Webserver
Act Now10ICS-CERT ICSA-17-264-04Sep 21, 2017
Attack VectorNetwork
Auth RequiredNone
ComplexityLow
User InteractionNone needed
Summary
The iniNet Webserver is vulnerable to authentication bypass due to improper authentication mechanisms (CWE-287). The vulnerability is remotely exploitable with low complexity and requires no credentials. It affects all versions below 2.02.0100. The iniNet Webserver is a third-party component used by many different vendors in their SCADA and industrial control products, particularly in the energy sector.
What this means
What could happen
An attacker on the network can gain unauthorized administrative access to SCADA systems using the iniNet Webserver without credentials, potentially allowing them to modify control setpoints, view sensitive process data, or disrupt operations.
Who's at risk
Energy utilities and critical infrastructure operators using SCADA systems that include the vulnerable iniNet Webserver component should be concerned. This impacts HMI (human-machine interface) servers, remote terminal units (RTUs), and other control system equipment from vendors that bundle the iniNet Webserver in versions prior to 2.02.0100.
How it could be exploited
An attacker accesses the iniNet Webserver web interface over the network and bypasses the authentication mechanism due to improper implementation of authentication checks. Once authenticated, the attacker can interact with the underlying SCADA system with administrative privileges.
Prerequisites
- Network access to the iniNet Webserver management interface (typically port 80 or 443)
- iniNet Webserver version below 2.02.0100 installed on the system
- No additional credentials or special configuration required

Remediation & Mitigation
0/5
Do now
0/2WORKAROUNDRestrict network access to the iniNet Webserver management interface using firewall rules to allow only trusted engineering workstations and authorized personnel
WORKAROUNDDisable remote access to the iniNet Webserver web interface if not required for operations; restrict to local network access only
Schedule — requires maintenance window
0/2Patching may require device reboot — plan for process interruption
HOTFIXIdentify all devices and systems in your environment using the iniNet Webserver; contact your equipment vendors to confirm if they have released patches that update or replace the vulnerable component
HOTFIXIf your vendor has released a patched version of their product (incorporating iniNet Webserver 2.02.0100 or later), apply the update during a planned maintenance window
Long-term hardening
0/1HARDENINGImplement network segmentation to isolate SCADA systems and control equipment from untrusted networks (e.g., corporate IT, internet)
