CVE-2025-10403 is a SQL Injection vulnerability identified in version 1.1 of the PHPGurukul Beauty Parlour Management System, specifically within the /admin/view-enquiry.php file. The vulnerability arises due to improper sanitization or validation of the 'viewid' parameter, which is used in SQL queries. An attacker can remotely manipulate this parameter to inject malicious SQL code, potentially allowing unauthorized access to the underlying database. This can lead to unauthorized data disclosure, data modification, or even complete compromise of the database server. The vulnerability requires no authentication or user interaction, making it exploitable by any remote attacker with network access to the affected system. The CVSS 4.0 score of 6.9 (medium severity) reflects the ease of exploitation (no privileges or user interaction required) but limited impact on confidentiality, integrity, and availability, as the vector components indicate low impact on these aspects. No known exploits are currently observed in the wild, but public disclosure of the exploit code increases the risk of exploitation. The vulnerability affects a niche product used primarily in beauty parlour management, which may limit its widespread impact but still poses a significant risk to organizations relying on this software for business operations and customer data management.

For European organizations using the PHPGurukul Beauty Parlour Management System, this vulnerability could lead to unauthorized access to sensitive customer data, including personal information and appointment details. Exploitation could result in data breaches, reputational damage, and potential regulatory penalties under GDPR due to inadequate protection of personal data. Additionally, attackers could alter or delete data, disrupting business operations and causing financial losses. Since the vulnerability is remotely exploitable without authentication, attackers could target exposed administrative interfaces, especially if these are accessible over the internet. The impact is particularly critical for small to medium enterprises in the beauty and wellness sector that may lack robust cybersecurity defenses or timely patch management processes.

Specific mitigation steps include: 1) Immediate application of patches or updates from PHPGurukul once available; if no official patch exists, implement input validation and parameterized queries (prepared statements) for the 'viewid' parameter to prevent SQL injection. 2) Restrict access to the /admin/view-enquiry.php page by implementing network-level controls such as IP whitelisting or VPN access to limit exposure to trusted users only. 3) Employ Web Application Firewalls (WAFs) configured to detect and block SQL injection attempts targeting the affected parameter. 4) Conduct regular security audits and code reviews focusing on input handling and database interactions. 5) Monitor logs for suspicious activities related to the 'viewid' parameter to detect potential exploitation attempts early. 6) Educate administrative users on the risks and encourage strong credential management to reduce the risk of lateral attacks if the vulnerability is exploited.
