CVE-2025-3796 is a critical SQL Injection vulnerability identified in version 1.0 of the PHPGurukul Men Salon Management System, specifically within the /admin/contact-us.php file. The vulnerability arises from improper sanitization and validation of user-supplied input parameters such as pagetitle, pagedes, email, mobnumber, and timing. An attacker can remotely manipulate these parameters to inject malicious SQL code into the backend database queries. This injection flaw allows unauthorized actors to execute arbitrary SQL commands, potentially leading to unauthorized data access, data modification, or deletion. The vulnerability is exploitable remotely without authentication, increasing the attack surface significantly. Although no public exploits have been observed in the wild yet, the disclosure of the vulnerability means attackers could develop and deploy exploits rapidly. The affected product is a niche salon management system used to manage appointments, customer data, and business operations, which likely stores sensitive customer and business information. The lack of available patches or mitigations from the vendor further exacerbates the risk. Given the nature of SQL injection, the vulnerability threatens the confidentiality, integrity, and availability of the system's data and could be leveraged to pivot into deeper network compromise if the system is connected to broader enterprise infrastructure.

For European organizations using the PHPGurukul Men Salon Management System, this vulnerability poses a significant risk to customer privacy and business continuity. Exploitation could lead to unauthorized disclosure of personal identifiable information (PII) such as customer contact details and appointment histories, violating GDPR requirements and potentially resulting in regulatory penalties. Data integrity could be compromised, leading to corrupted or falsified records that disrupt business operations and damage reputation. Availability impacts could arise if attackers execute destructive SQL commands or cause database crashes, resulting in service downtime. Since the system is used in customer-facing environments, such disruptions could directly affect revenue and customer trust. Additionally, if the compromised system is connected to internal networks, attackers might use it as a foothold for lateral movement, increasing the risk of broader organizational compromise. The medium severity rating in the source may underestimate the real-world impact given the ease of remote exploitation without authentication and the critical nature of SQL injection vulnerabilities.

Organizations should immediately conduct an inventory to identify any deployments of PHPGurukul Men Salon Management System version 1.0. If found, they should isolate the affected system from critical internal networks to limit potential lateral movement. Since no official patches are currently available, temporary mitigations include implementing Web Application Firewall (WAF) rules specifically designed to detect and block SQL injection attempts targeting the vulnerable parameters (pagetitle, pagedes, email, mobnumber, timing). Input validation and sanitization should be enforced at the application layer, ideally by updating or rewriting the vulnerable code to use parameterized queries or prepared statements. Regular database backups should be performed to enable recovery in case of data tampering or loss. Monitoring and logging of database queries and web application logs should be enhanced to detect suspicious activity. Organizations should also engage with the vendor for updates or patches and consider migrating to alternative, actively maintained salon management solutions if remediation is delayed. Finally, staff training on recognizing and responding to potential exploitation attempts can improve incident response readiness.
