PHP Web Explorer 0.99b - 'edit.php?File' Traversal Local File Inclusion

source: https://www.securityfocus.com/bid/31595/info
 
PHP Web Explorer is prone to multiple local file-include vulnerabilities because it fails to properly sanitize user-supplied input.
 
An attacker can exploit these vulnerabilities using directory-traversal strings to view local files and execute local scripts within the context of the webserver process. A successful attack can allow the attacker to obtain sensitive information or gain unauthorized access to an affected computer in the context of the vulnerable server.
 
PHP Web Explorer 0.99b is vulnerable; other versions may also be affected.
