Low risk9th percentile - higher than 9% of all known CVEs
Summary
The request handler of Fanvil x7a firmware version 2.6.0.1182 does not enforce any cross-origin resource protection for any state-changing request performed against the applications. Due to the lack of protection, the cross-origin boundary can be completely bypassed, allowing for Cross-Site Request Forgery Attacks against any endpoint.
Risk Assessment
An attacker can trick an authenticated administrator into unknowingly performing unauthorized operations on the device, potentially leading to configuration changes or full takeover of the VoIP phone.
Recommendation
Update Fanvil x7a firmware to a version newer than 2.6.0.1182 as soon as the vendor releases a fix, and restrict access to the management interface to trusted networks only.
