Suricata

Bug #418

Updated by Victor Julien almost 12 years ago

To avoid confusion with actual escaped characters this function should escape stray backslashes.   

 Example:  

 <pre> 
 nc www.openinfosecfoundation.org 80 
 GET /foo/\x80 HTTP/1.0                                          

 HTTP/1.1 404 Not Found 
 Date: Fri, 02 Mar 2012 19:41:33 GMT 
 Server:   
 Content-Length: 206 
 Connection: close 
 Content-Type: text/html; charset=iso-8859-1 

 </pre> 
 In Suricata this request will look like this in the http.log. 

 <pre> 
 03/02/2012-14:24:34.652663 <hostname unknown> [**] /foo/\x80 [**] <useragent unknown> [**] <no referer> [**] GET [**] HTTP/1.0 [**] 404 [**] 206 bytes [**].... 
 </pre> 

 Similar request in an Apache log.. 

 <pre> 
 127.0.0.1 - - [01/Feb/2012:09:23:52 -0600] "GET /foo/\\x80 HTTP/1.0" 404 484 "-" "-" 
 </pre>
