Horizon Alert
Summary of the vulnerability and why it matters
An authentication bypass vulnerability has been identified in the WebGUI of specific Series UNIVERGE IX-R/IX-V devices, allowing unauthorized users to execute commands on the affected systems. This issue arises from the ability to manipulate WebGUI messages and send them over the internet, potentially leading to unauthorized access and control of network devices.
- Unauthorized command execution via web interface.
- Affects internet-facing network management.
- Confirm relevance and exposure.
Attack Path
How an attacker could exploit the issue
An attacker can target the WebGUI of the Series UNIVERGE IX-R/IX-V by sending specially crafted messages over the internet. This bypasses authentication, allowing them to execute arbitrary command-line interface commands on the device. The vulnerability exists because the WebGUI messages can be tampered with to achieve this bypass.
- Accessible from the internet.
- Tampering with WebGUI messages.
- Bypass authentication, execute CLI commands.
Live Threat
Current exploitation, exposure, and threat context
This vulnerability could allow an unauthenticated attacker to bypass login controls for the WebGUI and execute arbitrary command-line interface commands on the device when messages are tampered with and sent over the internet.
- Device command execution
- Bypass authentication via tampered messages
- Unauthorized administrative access
Operational Fix
Recommended remediation, mitigation, and detection steps
The WebGUI of Series UNIVERGE IX-R/IX-V devices are likely managed by network or infrastructure teams. The first step is to identify all affected devices, confirm their internet reachability, and determine business criticality to prioritize remediation efforts.
- Network or Infrastructure teams own remediation.
- Verify internet-facing instances first.
- Plan for scheduled maintenance window.
