| 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). |

Additional Advisory Data
Solutions
CNA: The vulnerability has been fixed by the vendor through improved input validation logic and parameterized queries: It is recommended to update to firmware version 5.3 or higher. This version mitigates the risk by ensuring that SQL queries are handled securely, effectively neutralizing the injection vector.
Workarounds
CNA: If an immediate firmware update is not feasible, network-level controls must be implemented to reduce the attack surface: * Access Restriction: Limit access to the management or login panel using an Allowlist. All connection attempts from untrusted networks or the public internet must be strictly blocked. * Network Segmentation: Isolate the management interface within a dedicated management VLAN, accessible only through a secure corporate VPN.
