ThinkPHP 5.0.23 contains a remote code execution vulnerability that allows unauthenticated attackers to execute arbitrary PHP code by invoking functions through the routing parameter. Attackers can craft requests to the index.php endpoint with malicious function parameters to execute system commands with application privileges.
ThinkPHP Framework before 6.0.14 allows local file inclusion via the lang parameter when the language pack feature is enabled (lang_switch_on=true). An unauthenticated and remote attacker can exploit this to execute arbitrary operating system commands, as demonstrated by including pearcmd.php.
The package topthink/framework before 6.0.12 are vulnerable to Deserialization of Untrusted Data due to insecure unserialize method in the Driver class.
