CVE-2024-51064 identifies a critical SQL Injection vulnerability in the Phpgurukul Teachers Record Management System version 2.1. The vulnerability exists in the admin/queries.php script, specifically through the 'tid' parameter, which is improperly sanitized, allowing attackers to inject malicious SQL queries. This flaw enables unauthenticated remote attackers to manipulate backend database queries, potentially extracting sensitive data, modifying records, or causing denial of service by corrupting database integrity. The vulnerability is classified under CWE-89 (Improper Neutralization of Special Elements used in an SQL Command). The CVSS v3.1 base score is 9.8, reflecting network attack vector (AV:N), low attack complexity (AC:L), no privileges required (PR:N), no user interaction (UI:N), and full impact on confidentiality (C:H), integrity (I:H), and availability (A:H). No patches or official fixes have been released at the time of publication, and no known exploits have been observed in the wild, though the criticality suggests high exploitation potential. The vulnerability affects all installations of version 2.1 of this software, which is used primarily in educational environments to manage teacher records and related data. Attackers exploiting this vulnerability could gain unauthorized access to sensitive educational data, alter records, or disrupt system operations.

The impact of CVE-2024-51064 is severe for organizations using Phpgurukul Teachers Record Management System v2.1. Successful exploitation can lead to full database compromise, exposing sensitive teacher and student information, including personal identifiable information (PII), grades, and administrative data. Integrity of records can be compromised, leading to data manipulation or deletion, which can disrupt educational operations and damage institutional trust. Availability may also be affected if attackers corrupt or delete critical data, causing system downtime. The lack of authentication requirement and ease of exploitation increase the risk of widespread attacks. Educational institutions, especially those with limited cybersecurity resources, face significant operational and reputational risks. Additionally, regulatory compliance issues may arise due to data breaches involving personal information. The absence of known exploits currently provides a window for proactive defense, but the critical severity demands urgent attention.

To mitigate CVE-2024-51064, organizations should immediately restrict access to the admin/queries.php endpoint, ideally limiting it to trusted internal IP addresses or via VPN. Implement web application firewalls (WAFs) with custom rules to detect and block SQL injection patterns targeting the 'tid' parameter. Conduct thorough input validation and sanitization on all parameters, especially those interacting with SQL queries. Until an official patch is released, consider disabling or removing the vulnerable functionality if feasible. Regularly monitor logs for suspicious query patterns or repeated access attempts to the vulnerable endpoint. Educate administrators on the risks and signs of exploitation. Prepare an incident response plan to quickly address any detected compromise. Once a patch or update is available from the vendor, apply it promptly. Additionally, consider database-level protections such as least privilege access and query parameterization to reduce exploitation impact.
