CVE-2025-11507 identifies a SQL Injection vulnerability in the PHPGurukul Beauty Parlour Management System version 1.1, specifically within the /admin/search-invoices.php file. The vulnerability arises from improper sanitization of the 'searchdata' parameter, which is used in SQL queries without adequate validation or parameterization. This allows an unauthenticated remote attacker to inject arbitrary SQL commands by manipulating this input, potentially leading to unauthorized data access, modification, or deletion. The vulnerability does not require user interaction or prior authentication, increasing its risk profile. The CVSS 4.0 score of 6.9 reflects a medium severity, considering the attack vector is network-based with low complexity and no privileges required, but with limited impact on confidentiality, integrity, and availability. Although no known exploits have been observed in the wild, the public disclosure of exploit code increases the likelihood of exploitation attempts. The affected product is primarily used by small and medium-sized beauty parlour businesses to manage invoices and administrative tasks, making the data stored sensitive and critical for business operations. The lack of available patches or official vendor remediation at the time of publication necessitates immediate mitigation efforts by users.

For European organizations, particularly small and medium enterprises in the beauty and wellness sector using PHPGurukul Beauty Parlour Management System 1.1, this vulnerability poses a significant risk. Exploitation could lead to unauthorized access to sensitive financial and customer data, including invoices and potentially personal information. This compromises confidentiality and integrity, potentially resulting in data breaches, regulatory non-compliance (e.g., GDPR violations), reputational damage, and financial losses. Additionally, attackers could disrupt business operations by altering or deleting invoice records, impacting availability. The remote and unauthenticated nature of the attack vector increases the threat level, as attackers can exploit this vulnerability without insider access or user interaction. Given the public availability of exploit code, the risk of targeted attacks against European SMBs using this software is elevated. The impact is more pronounced in countries with a large number of small beauty parlour businesses relying on PHP-based management tools.

1. Immediate implementation of input validation and sanitization for the 'searchdata' parameter in /admin/search-invoices.php to prevent SQL injection. 2. Refactor the affected code to use parameterized queries or prepared statements to eliminate direct SQL concatenation. 3. Restrict access to the admin interface by IP whitelisting or VPN to limit exposure to trusted users only. 4. Monitor web server and application logs for suspicious query patterns indicative of SQL injection attempts. 5. If patching from the vendor becomes available, apply it promptly. 6. Conduct a security audit of the entire application to identify and remediate other potential injection points. 7. Educate staff on the risks of using outdated software and encourage timely updates. 8. Implement web application firewalls (WAF) with SQL injection detection rules tailored to the application’s traffic patterns. 9. Backup critical data regularly and ensure backups are stored securely to enable recovery in case of data tampering or loss. 10. Consider migrating to more secure, actively maintained management systems if feasible.
