Advisory Details:
High-Tech Bridge Security Research Lab discovered SQL injection vulnerability in b2evolution, which can be exploited to alter SQL requests passed to the vulnerable application's database. 1) SQL Injection in b2evolution: CVE-2013-2945 The vulnerability exists due to insufficient validation of HTTP GET parameter "show_statuses" in "/blogs/admin.php" script. A remote authenticated administrator can execute arbitrary SQL commands in application's database. Depending on database and system configuration, PoC code below will create a "/tmp/file.txt" file, containing MySQL version: http://[host]/blogs/admin.php?submit=Search&ctrl=items&tab=full&blog=1&show_ statuses[]=1') )) UNION SELECT version() INTO OUTFILE '/tmp/file.txt' -- This vulnerability is also exploitable via CSRF vector, since the application is prone to Cross-Site Request Forgery (CSRF) attacks. In order to do so an attacker should trick a logged-in administrator to visit malicious web page with CSRF exploit. Basic CSRF exploit: <img src="http://[host]/blogs/admin.php?submit=Search&ctrl=items&tab=full&blog=1& show_statuses[]=1') )) UNION SELECT version() INTO OUTFILE '/tmp/file.txt' --">
