Application Details
ThinkCMF is a content management framework built on the ThinkPHP+MYSQL combination.
Vulnerability
ThinkCMF is vulnerable to cross-site request forgery, caused by improper validation of user-supplied input.
Identification
By persuading an authenticated user to visit a malicious Web site, a remote attacker could send a malformed HTTP request to add a super admin user to the system. An attacker could exploit this vulnerability to perform cross-site scripting attacks, Web cache poisoning, and other malicious activities.
