PHP Live Helper libsecure.php code execution
| phplivehelper-libsecure-code-execution (44570) |  High Risk |
Description:
PHP Live Helper could allow a remote attacker to execute arbitrary code on the system, caused by the improper validation of user-supplied input passed to the libsecure.php script when register_globals is enabled. By sending a specially-crafted URL request, an attacker could exploit this vulnerability to overwrite the "database info" and "language file setting" db config file variables and execute arbitrary PHP code on the vulnerable system.
