PowerNews v1.1.0 (nbs) Remote File Inclusion

A remote file inclusion vulnerability exists in PowerNews v1.1.0 due to insufficient sanitization of user-supplied input to the 'nbs' parameter in the 'includes/global.php' script. An attacker can exploit this vulnerability to execute arbitrary PHP code on the vulnerable system by sending a specially crafted HTTP request containing a malicious URL in the 'nbs' parameter.

Mitigation:

Input validation should be used to prevent the inclusion of malicious files.
