How to Optimize MySQL

There is a default my.cnf that comes with mysql (4+5) that will make mysql run a bit quicker if you have 2+ gig of ram cp -f /usr/share/mysql/my-large.cnf /etc/my.cnfThere is also my-huge.cnf, or my-medium.cnf depending on your hardware setup.   Check the contents of these my*.cnf files for the one that’s right for you.

*NOTE* the log-bin option is enabled  by default.  This will quickly use a lot of disk space.  It’s recommended to comment out the log-bin line from your /etc/my.cnf, if it exists.


Remember to restart mysql when you are done with your my.cnf tweaking:

Redhat:/sbin/service mysqld restart

FreeBSD:/usr/local/etc/rc.d/mysqld restart

WHMCS SQL injection Exploit

** A patch was released. See  

WHMCS, a popular billing/support/customer management system, is still suffering from critical SQL injection issues. Today, yet another vulnerability, including exploit was released. 

Due to the fact that there is no patch available at this point, I will refrain from linking to any exploit details, but it is pretty trivial to find the respective blog post which includes a script to exploit the vulnerability. WHMCS acknowledged the problem.

The root cause of this problem, as well as prior problems with the software, appears to be a lack in understanding of proper controls to prevent SQL injection. Good input validation is just a start, but prepared statements are a must. Instead, the WHMCS developers used a rather complex (and buggy) function to escape user input and assemble dynamic SQL queries.

The bug is in a function used throughout WHMCS, so the exploit is not limited to a particular URL.

Zabbix 2.0.8 SQL Injection and Remote Code Execution

This exploits an unauthenticated SQL injection vulnerability affecting Zabbix versions 2.0.8 and lower.  The SQL injection issue can be abused in order to retrieve an active session ID.  If an administrator level user is identified, remote code execution can be gained by uploading and executing remote scripts via the 'scripts_exec.php' file.
