- Vulnerable GPON home routers
- Command injection flaw
- Unauthorized command execution
- Business disruption and data issues
Attack Path
How an attacker could exploit the issue
This vulnerability allows an attacker to execute arbitrary commands on a vulnerable router. The attacker can then leverage this access to gain control over the device. This could lead to the disruption of network services, data exfiltration, or further compromise of connected systems. The attack is facilitated by the router's method of saving and displaying ping test results.
- Exposure condition: Internet-facing router with web management interface.
- Attacker starting point: Unauthenticated network access.
- Trigger and result: Send crafted ping request, execute commands, retrieve output.
Live Threat
Current exploitation, exposure, and threat context
This vulnerability could allow an attacker to execute arbitrary commands on affected routers. The command injection occurs through a specific parameter in a web request. Successful exploitation can lead to the execution of malicious code and retrieval of sensitive information.
- Likely attacker skill level: Basic
- Required access or conditions: Network access
- Business risk or urgency: High
Priority actions
Operational Fix
Recommended remediation, mitigation, and detection steps
The identified command injection vulnerability in Dasan GPON home routers allows unauthenticated attackers to execute arbitrary commands and retrieve output through a network-accessible interface. This could lead to a compromise of the affected devices and potentially the broader network infrastructure. Organizations using these routers should prioritize identifying all instances within their environment and taking immediate steps to mitigate the associated risks.
- Identify all deployed Dasan GPON routers.
- Isolate or disable affected devices.
- Replace or decommission identified routers.
