Zinho's Security Advisory  

Desc: Maxwebportal 1.3.5 and prior 
Risk: High 


MaxWebPortal is probably the most spread ASP based web portal script. 
I've found multiple XSS and Sql injection that could easily lead to password strealing or  portal defacement. 

Proof of concept: 

Working Exploits: http://www.hackerscenter.com/archive/view.asp?id=2542 


XSS : 
--- Temporary XSS 
1./post.asp?method=Topic&FORUM_ID=1&  CAT_ID=1&Forum_Title=%00General+Chat&mod="><plaintext> 

2. /post.asp?method=Topic&FORUM_ID=1&  CAT_ID=1&Forum_Title=%00General+Chat&M="><plaintext> 

3. /post.asp?method=Topic&FORUM_ID=1&  CAT_ID=1&Forum_Title=%00General+Chat&type="><plaintext> 


---- Permanent XSS 
Try Posting using this url: 
1 ./post.asp?method=Topic&FORUM_ID=1& CAT_ID=1&Forum_Title=http://<plaintext> 






SQL Injections: 

1. fpassword parameter into function "ChkUser" defined into inc_functions.asp is not  checked. An SQL injection can be 
taken. 


2. "txtAddress", "message" and "subject" parameters into post_info.asp are not sanitized.  


3."andor" parameter added to the sql string on line 140 of search.asp 
search.asp?mode=DoIt  (Issued with method POST). An SQL injection can be taken 

4. verkey on line 132 of pop_profile.asp is not sanitized. An SQL injection can be taken 
pop_profile.asp?verkey=' 

5. SQL injection through Cookie alteration in pop_profile.asp (and all the other functions   that use authentication 
through Cookies) 

Anyone can change the password in the cokie to "'" and inject sql in the ChkUsr2  function 


6.  pm_delete2.asp Sql injection on line 85 - "Remove" parm is not sanitized 

7.  pm_delete2.asp - "Delete" parm is not sanitized 



Venodr has been contacted one month ago. 
They released the new version 1.3.6 that *should* (I've not checked) all the above.
