The vulnerability stems from weak authentication mechanisms within the application, potentially allowing an attacker with valid, low-privileged credentials to elevate their access to higher levels within the system. Successful exploitation would grant the attacker unauthorized access to sensitive data, configuration settings, and administrative functions within the Business Central environment.
