AWStats 7.0 / 6.0 SQL Injection / Cross Site Scripting / CRLF Injection

`Hello list!  
  
I want to warn you about multiple security vulnerabilities in AWStats.  
  
These are Cross-Site Scripting, Redirector, SQL Injection, HTTP Response  
Splitting and CRLF Injection vulnerabilities in AWStats (in awredir).  
  
-------------------------  
Affected products:  
-------------------------  
  
Vulnerable are all versions of AWStats (6.0, 7.0 and previous versions).  
  
----------  
Details:  
----------  
  
AWStats includes script Advanced Web Redirector (awredir.pl). There were  
already found (by trev and tx) XSS and Redirector vulnerabilities in  
awredir.pl in 2008 (http://sla.ckers.org/forum/read.php?3,23620). They have  
not mentioned about SQL Injection, maybe it was due to that affected  
functionality of the script was turned off by default.  
  
As I found, version awredir 1.1 (build 1.5) was not vulnerable to XSS, but  
version 1.1 (build 1.6) was already vulnerable.  
  
There are XSS, Redirector and SQL Injection vulnerabilities in version 1.1  
of the script. And in version 1.2 the protection was added - parameter key.  
Which can even be not used (if $KEYFORMD5 is empty), or it can be revealed  
by picking up. So the protection with key is not sufficient and can be  
bypassed. The parameter key will be needed for version 1.2 for conducting of  
Redirector, SQL Injection, HTTP Response Splitting and CRLF Injection  
attacks.  
  
In version 1.2 XSS was fixed, but Redirector and SQLi holes were left and  
HTTPRS, CRLF Injection and two new XSS were added.  
  
XSS (WASC-08) (in versions <=1.1):  
  
http://site/awredir.pl?url=javascript:alert(document.cookie)  
  
Redirector (URL Redirector Abuse in WASC 2.0) (WASC-38):  
  
http://site/awredir.pl?url=http://websecurity.com.ua  
  
In version 1.2:  
  
http://site/awredir.pl?key=0f3830803a70cc1636af3548b66ed978&url=http://websecurity.com.ua  
  
SQL Injection (WASC-19):  
  
http://site/awredir.pl?url='%20and%20benchmark(10000,md5(now()))/*  
  
In version 1.2:  
  
http://site/awredir.pl?key=f38ed1cdb04c8bda5386f7755a4e1d3e&url='%20and%20benchmark(10000,md5(now()))/*  
  
SQL Injection attack is possible if $TRACEBASE is turned on and DBI is  
included.  
  
XSS (WASC-08) (in version 1.2):  
  
http://site/awredir.pl?url=%3Cscript%3Ealert(document.cookie)%3C/script%3E  
  
http://site/awredir.pl?key=%3Cscript%3Ealert(document.cookie)%3C/script%3E  
  
HTTP Response Splitting (WASC-25):  
  
http://site/awredir.pl?key=04ed5362e853c72ca275818a7c0c5857&url=%0AHeader:1  
  
CRLF Injection (Improper Input Handling in WASC 2.0) (WASC-20):  
  
http://site/awredir.pl?key=4b9faa91e2529400c4f3c70833b4e4a5&url=%0AText  
  
CRLF Injection in logs is possible at turned on $DEBUG and/or $TRACEFILE.

Timeline:  
------------  
  
2008.07.22 - after informing developers, trev and tx disclosed XSS and  
Redirector holes. After which developers should fixed them correctly (and  
also SQLi) and without adding new holes.  
2011.09.17 - informed developers.  
2011.09.22 - disclosed at my site.  
  
I mentioned about these vulnerabilities at my site:
