The vulnerability is due to insufficient validation of user-controlled parameters in HTTP POST requests. An attacker could exploit this vulnerability by sending an HTTP POST request with crafted user parameters that update the system time maliciously. An exploit could allow the attacker to impact the integrity of the system because the user parameters are not properly validated.
