CVE-2025-4940 is a SQL Injection vulnerability identified in version 1.0 of the '1000 Projects Daily College Class Work Report Book' software. The vulnerability resides in the /admin_info.php file, specifically in the handling of the 'batch' parameter. An attacker can remotely manipulate this parameter to inject malicious SQL code, potentially allowing unauthorized access or modification of the backend database. The vulnerability does not require any authentication or user interaction, making it exploitable over the network by unauthenticated attackers. The CVSS 4.0 base score is 6.9, indicating a medium severity level, with the vector highlighting network attack vector (AV:N), low attack complexity (AC:L), no privileges required (PR:N), no user interaction (UI:N), and limited impact on confidentiality, integrity, and availability (VC:L, VI:L, VA:L). Although the exploit has been publicly disclosed, there are no known exploits actively used in the wild at this time. The vulnerability's root cause is improper sanitization or validation of the 'batch' parameter, which allows SQL commands to be injected and executed on the database server. This could lead to unauthorized data disclosure, data manipulation, or potentially further compromise of the system depending on the database privileges and application architecture. The lack of a patch link suggests that a fix may not yet be available, increasing the urgency for affected organizations to implement mitigations.

For European organizations using the '1000 Projects Daily College Class Work Report Book' software, this vulnerability poses a significant risk to the confidentiality and integrity of educational data, including student records and class reports. Exploitation could lead to unauthorized access to sensitive academic information, data tampering, or disruption of reporting functions. Given the software's use in educational institutions, a successful attack could undermine trust, violate data protection regulations such as GDPR, and result in reputational damage. The remote and unauthenticated nature of the exploit increases the risk of widespread attacks, especially in institutions with internet-facing installations of the affected software. Additionally, compromised systems could be leveraged for further attacks within the network, potentially affecting other critical educational infrastructure.

Immediate mitigation steps include restricting external access to the /admin_info.php endpoint through network-level controls such as firewalls or VPNs, limiting exposure to trusted internal networks only. Organizations should implement web application firewalls (WAFs) with rules to detect and block SQL injection patterns targeting the 'batch' parameter. Input validation and sanitization should be enforced at the application level to reject malicious input. Until an official patch is released, administrators should monitor logs for suspicious activity related to the 'batch' parameter and conduct regular security audits. Additionally, applying the principle of least privilege to the database user accounts used by the application can reduce the impact of a successful injection. Backup procedures should be reviewed and tested to ensure data recovery in case of compromise. Finally, organizations should stay updated with vendor advisories for any forthcoming patches or updates.
