Detailed vulnerability description
The disclosed vulnerability allows a remote attacker to perform SSRF attacks.
The vulnerability exists in the "copy" function in "application/admin/controller/Article.php" because URL validation only considers whether the URL contains the "csdn" substring. A remote attacker can send a specially crafted HTTP request, trick the application to initiate requests to arbitrary systems and access the content of internal and external network resources.
Successful exploitation of this vulnerability may allow a remote attacker gain access to sensitive data, located in the local network or send malicious requests to other servers from the vulnerable system.
