A vulnerability was found in PHPGurukul Teachers Record Management System 2.1. It has been classified as critical. This affects an unknown part of the file /admin/changeimage.php. The manipulation of the argument tid leads to sql injection. It is possible to initiate the attack remotely. The exploit has been disclosed to the public and may be used.
AI Analysis
Technical Summary
CVE-2025-6888 is a critical SQL Injection vulnerability identified in version 2.1 of the PHPGurukul Teachers Record Management System, specifically within the /admin/changeimage.php file. The vulnerability arises from improper sanitization or validation of the 'tid' parameter, which is used in SQL queries. An attacker can remotely manipulate this parameter to inject malicious SQL code, potentially allowing unauthorized access to the backend database. This can lead to unauthorized data disclosure, data modification, or even complete compromise of the database server. The vulnerability requires no authentication or user interaction, making it highly exploitable. Although the CVSS 4.0 score is 6.9 (medium severity), the potential impact on confidentiality, integrity, and availability is significant due to the nature of SQL injection attacks. The exploit has been publicly disclosed, increasing the risk of exploitation by threat actors. No official patches or fixes have been linked yet, which means affected organizations must rely on mitigation strategies until a vendor patch is available.
Potential Impact
For European organizations using PHPGurukul Teachers Record Management System 2.1, this vulnerability poses a substantial risk. Educational institutions and administrative bodies managing teacher records could face unauthorized data breaches, exposing sensitive personal information such as identities, qualifications, and employment history. This could lead to privacy violations under GDPR, resulting in legal penalties and reputational damage. Furthermore, attackers could manipulate or delete records, disrupting administrative operations and potentially impacting payroll or certification processes. The remote and unauthenticated nature of the exploit increases the likelihood of attacks, especially in environments where the system is exposed to the internet or insufficiently segmented networks. The lack of a patch and public exploit disclosure further exacerbate the threat landscape for these organizations.
Mitigation Recommendations
1. Immediate mitigation should include restricting access to the /admin/changeimage.php endpoint via network controls such as firewalls or VPNs, limiting it to trusted administrative IP addresses only. 2. Implement Web Application Firewall (WAF) rules to detect and block SQL injection patterns targeting the 'tid' parameter. 3. Conduct a thorough audit of all input validation and sanitization mechanisms in the application, especially for parameters used in SQL queries, and apply parameterized queries or prepared statements where possible. 4. If feasible, temporarily disable the vulnerable functionality until a vendor patch is released. 5. Monitor logs for unusual database query patterns or failed login attempts that may indicate exploitation attempts. 6. Educate administrative users about the risk and encourage the use of strong authentication methods to reduce lateral movement if compromise occurs. 7. Engage with the vendor or community to obtain or develop patches and apply them promptly once available.
