This vulnerability (CVE-2025-65133) affects the School Management System version 1.0 by manikandan580. It is a SQL injection flaw (CWE-89) that permits remote attackers, without requiring authentication, to craft HTTP requests that alter the logic of SQL queries executed by the application. Successful exploitation can lead to unauthorized disclosure of sensitive database information and potentially full compromise of the system's data integrity and availability. The CVSS v3.1 base score is 9.8 (AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H), reflecting a critical severity with network attack vector, low attack complexity, no privileges or user interaction needed, and high impact on confidentiality, integrity, and availability. No patch or official remediation level has been published, and the affected version detail is unspecified beyond version 1.0. The system is not a cloud service, so remediation depends on vendor or user action.

Exploitation of this vulnerability can lead to complete compromise of the affected system's database, including unauthorized disclosure, modification, or deletion of sensitive data. The critical CVSS score indicates a severe risk to confidentiality, integrity, and availability. Because the vulnerability is exploitable remotely without authentication or user interaction, it poses a significant threat to any deployment of the affected software.

Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is available, users should consider applying web application firewalls or input validation controls to detect and block SQL injection attempts. Monitoring and restricting access to the affected endpoints may reduce exposure. Avoid exposing the vulnerable system to untrusted networks if possible.
