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 without adequate protection against injection attacks. An attacker can remotely manipulate this parameter to inject malicious SQL code, potentially allowing unauthorized access to or modification of the backend database. This can lead to unauthorized data disclosure, data manipulation, or even complete compromise of the application’s data integrity and confidentiality. The vulnerability does not require authentication or user interaction, making it exploitable by any remote attacker with network access to the affected system. The CVSS 4.0 base score is 6.9, indicating a medium severity level, with the vector highlighting that the attack is network-based, requires no privileges or user interaction, and impacts confidentiality, integrity, and availability to a limited extent. Although no known exploits are currently in the wild, the public disclosure of the exploit code increases the risk of exploitation. The vulnerability affects a niche management system used primarily in beauty parlour business environments, which may have limited but sensitive customer and appointment data stored. The lack of available patches or vendor advisories at the time of publication increases the urgency for organizations to implement mitigations.

For European organizations using the PHPGurukul Beauty Parlour Management System version 1.1, this vulnerability poses a significant risk to the confidentiality and integrity of customer and business data. Exploitation could lead to unauthorized access to appointment details, personal customer information, and potentially payment or billing data if stored in the same database. This could result in privacy violations under GDPR, leading to regulatory penalties and reputational damage. Additionally, data manipulation could disrupt business operations, causing appointment scheduling errors or denial of service conditions. Since the vulnerability is remotely exploitable without authentication, attackers could leverage it to gain a foothold in the network, potentially pivoting to other internal systems. The impact is particularly critical for small to medium-sized enterprises in the beauty and wellness sector, which may lack robust cybersecurity defenses and incident response capabilities. The medium severity rating suggests that while the vulnerability is serious, it may not lead to full system compromise without additional vulnerabilities or misconfigurations.

Given the absence of official patches, European organizations should immediately implement compensating controls. First, restrict network access to the /admin/view-appointment.php endpoint by limiting it to trusted IP addresses or VPN access only. Implement Web Application Firewall (WAF) rules specifically designed to detect and block SQL injection attempts targeting the 'viewid' parameter. Conduct thorough input validation and sanitization on all user-supplied data, especially parameters used in SQL queries, employing prepared statements or parameterized queries if possible. Regularly audit and monitor database logs for suspicious queries or anomalies. Organizations should also consider isolating the affected application within segmented network zones to limit lateral movement in case of compromise. Finally, plan for an upgrade or migration to a patched or alternative management system once available, and maintain regular backups of critical data to enable recovery from potential data corruption or loss.
