Horizon Alert
Summary of the vulnerability and why it matters
A critical command injection vulnerability has been identified in N.V.K. INTER CO., LTD.'s iBSG product. This flaw, located in the network configuration interface, could allow an unauthorized individual to execute arbitrary commands on the affected system, potentially impacting network operations and security. The main concern is confirming relevance and exposure.
- Enables attackers to run commands remotely.
- Critical flaw impacts network gateway security.
- Confirm if your network gateways are affected.
Attack Path
How an attacker could exploit the issue
An attacker could exploit this vulnerability by sending a specially crafted request over the network to the vulnerable device. This request would target the `system_hostname` parameter in the `/manage/network-basic.php` script, allowing the attacker to inject malicious commands that the system would then execute. If successful, this could allow the attacker to compromise the device's integrity and availability.
- Network access is required.
- Injecting commands via `system_hostname` parameter.
- Leads to device compromise and control.
Live Threat
Current exploitation, exposure, and threat context
The iBSG system's network configuration could be compromised through a command injection vulnerability. When supported by the advisory, an unauthenticated attacker could leverage this flaw by sending a specially crafted request to the `system_hostname` parameter on the `/manage/network-basic.php` endpoint. This could allow an attacker to execute arbitrary commands on the affected system.
- System configuration and commands at risk.
- Via unauthenticated network request to `/manage/network-basic.php`.
- Arbitrary command execution on the system.
Operational Fix
Recommended remediation, mitigation, and detection steps
This command injection vulnerability in NVK's Intelligent Broadband Subscriber Gateway (iBSG) likely impacts network or security teams responsible for managing subscriber access and network edge devices. The initial practical step is to identify all deployed iBSG instances, assess their exposure and criticality, and then coordinate with the vendor for a risk-based remediation plan.
- Network or security teams should own this.
- Verify external reachability and business impact.
- Plan remediation with vendor support.
