CVE-2025-70521
UnknownSummary
The management portal's diagnostic ping tool of Fanvil x7a firmware version 2.6.0.1182 does not handle user-supplied input securely. The lack of secure user input handling allows any unauthenticated attacker to inject commands and run code in the underlying Android operating system.
Risk Assessment
An unauthenticated attacker can remotely execute arbitrary commands in the device's operating system, resulting in full compromise of the VoIP phone.
Recommendation
Update Fanvil x7a firmware to a version newer than 2.6.0.1182 once the vendor releases a fix, and isolate VoIP devices in a dedicated VLAN.
