Platform
Product: Symphony Vendor: http://getsymphony.com/ Vulnerable Version(s): 2.3.1 and probably prior Tested Version: 2.3.1 Vendor Notification: March 13, 2013 Vendor Patch: March 24, 2013 Public Disclosure: April 3, 2013 Vulnerability Type: SQL Injection [CWE-89] CVE Reference: CVE-2013-2559 Risk Level: Medium CVSSv2 Base Score: 5.1 (AV:N/AC:H/Au:N/C:P/I:P/A:P) Solution Status: Fixed by Vendor Discovered and Provided: High-Tech Bridge Security Research Lab ( https://www.htbridge.com/advisory/ ) ----------------------------------------------------------------------------------------------- Advisory Details: High-Tech Bridge Security Research Lab discovered SQL injection vulnerability in Symphony, which can be exploited to alter SQL requests to database of the vulnerable application. 1) SQL Injection in Symphony: CVE-2013-2559 The vulnerability exists due to insufficient filtration of "sort" HTTP GET parameter passed via "/symphony/system/authors/" URL to "/index.php" script. A remote authenticated administrator can execute arbitrary SQL commands in the application's database. Depending on database and system configuration, this PoC (Proof of Concept) code will create "/var/www/file.txt" file, containing users account information (logins, hashed passwords, etc.) from the "authors" table: http://[host]/symphony/system/authors/?order=asc&sort=id%20INTO%20OUTFILE%20%27/var/www/file.txt%27%20--%20 This vulnerability could also be exploited by a remote non-authenticated attacker via CSRF vector, since the application is prone to Cross-Site Request Forgery (CSRF) attacks. In order to do so an attacker should trick the logged-in administrator to visit a web page with CSRF exploit: <img src="http://[host]/symphony/system/authors/?order=asc&sort=id%20INTO%20OUTFILE%20%27/var/www/file.txt%27%20--%20"> ----------------------------------------------------------------------------------------------- Solution: Upgrade to Symphony 2.3.2 More Information: http://getsymphony.com/download/releases/version/2.3.2/ https://github.com/symphonycms/symphony-2/commit/6c8aa4e9c810994f7632837487426867ce50f468 ----------------------------------------------------------------------------------------------- References: [1] High-Tech Bridge Advisory HTB23148 - https://www.htbridge.com/advisory/HTB23148 - SQL Injection Vulnerability in Symphony.
