CVE-2025-9933 is a SQL Injection vulnerability identified in version 1.1 of the PHPGurukul Beauty Parlour Management System, specifically within the /admin/view-appointment.php file. The vulnerability arises due to improper sanitization or validation of the 'viewid' parameter, which is used in SQL queries. An attacker can manipulate this parameter remotely without any authentication or user interaction to inject malicious SQL code. This can lead to unauthorized access to the backend database, allowing attackers to read, modify, or delete sensitive data related to appointments, customers, or administrative information. The vulnerability is exploitable over the network (AV:N), requires no privileges (PR:N), no user interaction (UI:N), and has low complexity (AC:L), making it relatively easy to exploit. The impact on confidentiality, integrity, and availability is limited but present (VC:L, VI:L, VA:L), indicating that while the damage may not be catastrophic, it can still compromise sensitive data and system reliability. The vulnerability has been publicly disclosed, but no known exploits are currently reported in the wild. The CVSS v4.0 base score is 6.9, categorizing it as a medium severity issue. Given the nature of SQL injection, attackers could potentially escalate the impact by chaining with other vulnerabilities or gaining further access to the system.

For European organizations using PHPGurukul Beauty Parlour Management System 1.1, this vulnerability poses a moderate risk. Compromise of appointment and customer data could lead to breaches of personal data protected under GDPR, resulting in legal and financial repercussions. Unauthorized database access could also disrupt business operations, damage reputation, and erode customer trust. Since the system is targeted at beauty parlours, which often handle personal and payment information, the exposure of such data could have significant privacy implications. Additionally, attackers might leverage this vulnerability as a foothold for further attacks within the network. The remote and unauthenticated nature of the exploit increases the risk of widespread exploitation if the software is deployed in multiple European countries without timely patching or mitigation.

1. Immediate mitigation should include restricting access to the /admin/view-appointment.php page via network controls such as IP whitelisting or VPN access to limit exposure. 2. Implement web application firewall (WAF) rules specifically designed to detect and block SQL injection attempts targeting the 'viewid' parameter. 3. Upgrade or patch the PHPGurukul Beauty Parlour Management System to a version where this vulnerability is fixed; if no patch is available, consider applying custom input validation and parameterized queries to sanitize 'viewid'. 4. Conduct thorough code review and penetration testing focusing on SQL injection vectors in the application. 5. Monitor logs for suspicious activities related to SQL errors or unusual database queries. 6. Educate administrators and users about the risks and signs of exploitation. 7. If possible, isolate the management system from critical internal networks to reduce lateral movement risk.
