CVE-2025-11416 identifies a SQL injection vulnerability in the PHPGurukul Beauty Parlour Management System version 1.1, specifically within the /admin/invoices.php file. The vulnerability arises from improper sanitization of the 'delid' parameter, which is used in SQL queries without adequate validation or parameterization. An attacker can remotely send crafted requests manipulating the 'delid' argument to inject arbitrary SQL commands. This can lead to unauthorized data access, modification, or deletion within the underlying database. The vulnerability is exploitable without authentication, user interaction, or privileges, making it highly accessible to attackers. The CVSS 4.0 score of 6.9 (medium severity) reflects the network attack vector, low complexity, and no required privileges, but limited impact on confidentiality, integrity, and availability (all rated low). Although no confirmed exploits are observed in the wild, public exploit code availability increases the risk of exploitation. The lack of official patches or vendor advisories necessitates urgent attention from users of this software. The vulnerability affects only version 1.1 of the product, which is typically deployed in small to medium beauty parlour businesses for managing invoices and administrative tasks. The attack surface is primarily the admin panel, which may be exposed to the internet or internal networks. Exploitation could lead to data breaches involving customer information, financial records, or operational data, potentially causing reputational damage and regulatory compliance issues.

For European organizations using PHPGurukul Beauty Parlour Management System 1.1, this vulnerability poses a significant risk of unauthorized data access and manipulation. The SQL injection could allow attackers to extract sensitive customer data, financial details, or internal business information, leading to privacy violations and potential GDPR non-compliance. Data integrity could be compromised by unauthorized modifications or deletions, disrupting business operations and financial reporting. Availability impact is limited but possible if attackers execute destructive queries. The ease of exploitation without authentication increases the threat level, especially for businesses with exposed or poorly secured admin interfaces. Small and medium enterprises in the beauty and wellness sector, which may lack robust cybersecurity measures, are particularly vulnerable. The reputational damage and potential fines from data breaches could have severe financial consequences. Additionally, attackers could leverage the vulnerability as a foothold for further network intrusion or lateral movement within organizational IT environments.

Since no official patches are currently available, European organizations should implement immediate compensating controls. First, restrict access to the /admin/invoices.php interface by IP whitelisting or VPN-only access to limit exposure. Implement web application firewall (WAF) rules specifically targeting SQL injection patterns on the 'delid' parameter to block malicious requests. Conduct code review and apply manual input validation and parameterized queries or prepared statements for the 'delid' parameter to prevent injection. Regularly monitor logs for suspicious activity targeting the admin panel. Educate administrative users about the risk and enforce strong authentication and session management to reduce risk of unauthorized access. Consider isolating the vulnerable system from critical networks until a vendor patch or update is released. Backup databases frequently to enable recovery in case of data tampering. Engage with PHPGurukul or community forums to track patch releases and apply updates promptly once available.
