  WebServer 4 Everyone Directory Traversal Bug
------------------------------------------------------------------------

SUMMARY

 <http://www.freeware.lt/body_w4a_us.html> WebServer 4 Everyone is an easy
to use web server, however, the product has been found to contain a
security vulnerability that would allow an attacker to cause it to display
files that reside outside the bounding HTML root directory.

DETAILS

Vulnerable systems:
 * WebServer 4 Everyone version 1.22

Immune systems:
 * WebServer 4 Everyone version 1.23

A security problem is caused by the character '\' (%5c). Since it is not
filtered out from incoming requests, the server will follow the path in
the URI that the attacker give until it reaches the file requested.

Example:
http://host/%5c%2e%2e%5c%2e%2e%5c%2e%2e%5cboot.ini
Or
GET /\..\..\..\..\..\boot.ini HTTP/1.0
