Description
A critical SQL Injection (SQLi) vulnerability has been identified in the authentication module of the system. An unauthenticated, remote attacker (AV:N/PR:N) can exploit this flaw by sending specially crafted SQL queries through the login interface. Due to low attack complexity (AC:L) and the absence of specific requirements (AT:N), the vulnerability allows for a total compromise of the system's configuration data (VC:H/VI:H). While the availability of the service remains unaffected (VA:N), the breach may lead to a limited exposure of sensitive information regarding subsequent or interconnected systems (SC:L).
