Busy box httpd file traversal vulenrability

[bug-finder () hotmail com]

a file traversal attack is possible in busybox's http daemon when you send a url encoded slash like this 
http://attacked-host//%2e%2e/%2e%2e/%2e%2e/%2e%2e/%2e%2e/etc/passwd I have tested with busy box 1.01 and I dont know if 
other versions are vulenrable
