CVE-2025-4297 is a critical SQL Injection vulnerability identified in version 2.0 of the PHPGurukul Men Salon Management System, specifically within the /admin/change-password.php file. The vulnerability arises due to improper sanitization or validation of user-supplied input parameters, allowing an attacker to inject malicious SQL queries directly into the backend database. This injection can be performed remotely without any authentication or user interaction, increasing the attack surface significantly. The vulnerability affects multiple parameters, although the exact parameters are unspecified. Exploiting this flaw could enable an attacker to manipulate database queries, potentially leading to unauthorized data access, data modification, or deletion, and could compromise the confidentiality, integrity, and availability of the system's data. Despite the CVSS 4.0 score of 6.9 (medium severity), the nature of SQL Injection vulnerabilities often allows for severe consequences depending on the database content and privileges. No official patches or mitigations have been published yet, and while no known exploits are currently active in the wild, public disclosure of the exploit code increases the risk of exploitation.

For European organizations using the PHPGurukul Men Salon Management System 2.0, this vulnerability poses a significant risk. Successful exploitation could lead to unauthorized access to sensitive customer data, including personal and payment information, which would violate GDPR regulations and result in substantial legal and financial penalties. The integrity of business-critical data could be compromised, affecting operational continuity and customer trust. Additionally, attackers could leverage this vulnerability to escalate privileges or pivot within the network, potentially impacting other connected systems. Given the remote and unauthenticated nature of the exploit, attackers can target vulnerable installations over the internet, increasing the likelihood of widespread impact, especially for small to medium enterprises in the salon and personal care sector that may lack robust cybersecurity defenses.

1. Immediate code review and sanitization: Developers should audit the /admin/change-password.php script to identify all input parameters and implement strict input validation and parameterized queries (prepared statements) to prevent SQL Injection. 2. Implement Web Application Firewalls (WAF): Deploy WAFs with rules specifically designed to detect and block SQL Injection attempts targeting this application. 3. Network segmentation and access controls: Restrict administrative interface access to trusted IP addresses or VPN-only access to reduce exposure. 4. Monitor logs and alerts: Enable detailed logging of database queries and web requests to detect anomalous activities indicative of exploitation attempts. 5. Prompt patching: Engage with PHPGurukul or community maintainers for official patches or updates and apply them immediately upon release. 6. Backup and recovery planning: Ensure regular backups of databases and application data to enable rapid restoration in case of compromise. 7. Security awareness: Train staff managing the system on recognizing suspicious activities and maintaining secure configurations.
