## Description

WWBN AVideo through commit 9c39d8c8 contains a cross-site request forgery vulnerability in the get_domain() and isSameDomain() functions that fail to properly validate referer origins. Attackers can forge requests from sibling subdomains or unparseable long-gTLD origins to perform administrative ObjectYPT writes including live server configuration changes.
