A CSRF (Cross Site Request Forgery) in the web interface of the Yeahlink Ultra-elegant IP Phone SIP-T41P firmware version 66.83.0.35 allows a remote attacker to trigger code execution or settings modification on the device by providing a crafted link to the victim.
The web application does not, or cannot, sufficiently verify whether a request was intentionally provided by the user who sent the request, which could have originated from an unauthorized actor.
