CVE-2025-9831 is a SQL Injection vulnerability identified in version 1.1 of the PHPGurukul Beauty Parlour Management System, specifically within the /admin/edit-services.php file. The vulnerability arises due to improper sanitization or validation of the 'sername' parameter, which an attacker can manipulate to inject malicious SQL code. This flaw allows an unauthenticated remote attacker to execute arbitrary SQL queries on the backend database without requiring any user interaction or privileges. The CVSS 4.0 base score of 6.9 reflects a medium severity, indicating that while the attack vector is network-based and requires no authentication or user interaction, the impact on confidentiality, integrity, and availability is limited to low levels. The vulnerability does not affect system components beyond the database scope, and no privilege escalation or system-level compromise is directly indicated. Although no public exploits are currently observed in the wild, the exploit code has been publicly disclosed, increasing the risk of exploitation. The vulnerability's presence in an administrative interface suggests that successful exploitation could allow attackers to manipulate service data, potentially leading to unauthorized data disclosure, data modification, or denial of service within the application context. Given the nature of the affected software—a niche management system for beauty parlours—the attack surface is relatively narrow but still significant for organizations relying on this product for their business operations.

For European organizations using PHPGurukul Beauty Parlour Management System 1.1, this vulnerability could result in unauthorized access to sensitive business data, including service configurations and possibly customer information stored within the database. The SQL injection could allow attackers to extract confidential data, alter service details, or disrupt service availability, impacting business continuity and customer trust. While the direct impact on critical infrastructure is limited, small and medium enterprises in the beauty and wellness sector could face operational disruptions and reputational damage. Additionally, data breaches involving personal customer data could trigger regulatory scrutiny under GDPR, leading to potential fines and legal consequences. The remote and unauthenticated nature of the exploit increases the risk, especially if the management system is exposed to the internet without adequate network protections. The medium severity rating suggests that while the threat is serious, it is not likely to cause widespread or catastrophic damage but should be addressed promptly to avoid escalation.

Organizations should immediately audit their use of PHPGurukul Beauty Parlour Management System 1.1 and restrict access to the /admin/edit-services.php endpoint to trusted internal networks only, using network segmentation and firewall rules. Input validation and parameterized queries should be implemented or verified in the application code to prevent SQL injection. If vendor patches or updates become available, they should be applied without delay. In the absence of official patches, deploying Web Application Firewalls (WAFs) with custom rules to detect and block SQL injection patterns targeting the 'sername' parameter can provide interim protection. Regular database backups and monitoring for unusual query patterns or access attempts should be established to detect exploitation attempts early. Additionally, organizations should review and limit database user privileges to minimize the impact of potential SQL injection attacks. Conducting security assessments and penetration testing focused on this vulnerability can help validate the effectiveness of mitigations.
