CVE-2025-11415 identifies a SQL injection vulnerability in PHPGurukul Beauty Parlour Management System version 1.1, specifically in the /admin/customer-list.php file's delid parameter. This parameter is susceptible to injection due to insufficient input validation or sanitization, allowing attackers to craft malicious SQL statements that the backend database executes. The vulnerability is remotely exploitable without requiring authentication or user interaction, which significantly lowers the barrier for attackers. Successful exploitation can lead to unauthorized data retrieval, modification, or deletion, compromising the confidentiality, integrity, and availability of the system's data. The vulnerability is categorized with a CVSS 4.0 base score of 6.9 (medium severity), reflecting its network attack vector, low complexity, and no required privileges or user interaction. Although no active exploits have been reported in the wild, publicly available exploit code increases the likelihood of future attacks. The affected product is primarily used by beauty parlour businesses for customer management, billing, and scheduling, making the data involved sensitive and critical for business operations. The lack of vendor-provided patches or mitigations at the time of publication necessitates immediate defensive measures by users.

For European organizations, particularly small and medium enterprises (SMEs) in the beauty and wellness sector using PHPGurukul Beauty Parlour Management System 1.1, this vulnerability poses significant risks. Exploitation could lead to unauthorized access to customer data, including personal and payment information, resulting in privacy violations and potential regulatory non-compliance under GDPR. Data integrity could be compromised, leading to incorrect billing or scheduling, damaging business operations and reputation. Availability impacts may arise if attackers manipulate or delete critical data, causing service disruptions. Given the remote and unauthenticated nature of the exploit, attackers can launch attacks at scale, potentially affecting multiple businesses simultaneously. The public availability of exploit code increases the threat landscape, making timely mitigation essential to prevent data breaches and operational downtime.

Immediate mitigation should focus on applying vendor patches once available. In the absence of official patches, organizations should implement strict input validation and sanitization on the delid parameter, employing parameterized queries or prepared statements to prevent SQL injection. Web application firewalls (WAFs) can be configured to detect and block SQL injection patterns targeting the vulnerable endpoint. Regular security audits and code reviews should be conducted to identify similar vulnerabilities. Additionally, restricting access to the /admin directory via IP whitelisting or VPN can reduce exposure. Organizations should monitor logs for suspicious activities related to the delid parameter and establish incident response plans to quickly address potential breaches. Finally, educating staff about the risks and signs of exploitation can enhance overall security posture.
