CVE-2025-11415 identifies a SQL injection vulnerability in the PHPGurukul Beauty Parlour Management System version 1.1, specifically within the /admin/customer-list.php script. The vulnerability arises from improper sanitization of the 'delid' parameter, which is used in SQL queries without adequate validation or parameterization. This flaw allows remote attackers to inject arbitrary SQL code by manipulating the 'delid' argument, enabling unauthorized access to or modification of the underlying database. The attack vector is network-based, requiring no authentication or user interaction, making it highly accessible to attackers. The CVSS 4.0 base score of 6.9 (medium severity) reflects the moderate impact on confidentiality, integrity, and availability, with low complexity and no privileges required. Although no active exploitation has been reported, a public exploit is available, increasing the likelihood of future attacks. The vulnerability primarily threatens data confidentiality and integrity, potentially allowing attackers to extract sensitive customer information, delete or alter records, or disrupt service availability. The affected product is niche software used by beauty parlour businesses, typically small to medium enterprises, which may lack robust cybersecurity defenses. The absence of official patches or updates necessitates immediate mitigation efforts by users. The vulnerability underscores the importance of secure coding practices, such as input validation and use of prepared statements, especially in web applications handling sensitive customer data.

For European organizations, particularly small and medium-sized enterprises (SMEs) in the beauty and wellness sector using PHPGurukul Beauty Parlour Management System 1.1, this vulnerability poses a significant risk. Exploitation can lead to unauthorized disclosure of customer data, including personal and possibly payment information, damaging customer trust and violating data protection regulations like GDPR. Data integrity could be compromised, allowing attackers to alter or delete records, disrupting business operations and potentially causing financial loss. Availability impacts may arise if attackers manipulate the database to cause application crashes or denial of service. Given the remote, unauthenticated nature of the exploit, attackers can easily target vulnerable systems over the internet, increasing exposure. The public availability of exploits heightens the risk of automated scanning and mass exploitation campaigns. European organizations may face regulatory penalties and reputational damage if breaches occur. The impact is more pronounced in countries with a larger market share of PHP-based management tools and a dense network of beauty parlours relying on such software for daily operations.

To mitigate CVE-2025-11415, affected organizations should implement the following specific measures: 1) Immediately restrict access to the /admin/customer-list.php page by IP whitelisting or VPN-only access to reduce exposure. 2) Employ web application firewalls (WAFs) with custom rules to detect and block SQL injection attempts targeting the 'delid' parameter. 3) If source code access is available, refactor the vulnerable code to use parameterized SQL queries or prepared statements, eliminating direct concatenation of user input into SQL commands. 4) Implement rigorous input validation and sanitization on all parameters, especially those used in database queries. 5) Monitor logs for unusual database query patterns or repeated access attempts to the vulnerable endpoint. 6) Conduct regular security assessments and penetration testing focused on injection flaws. 7) If patching is not immediately possible, consider isolating the affected system from the internet or placing it behind a reverse proxy with filtering capabilities. 8) Educate staff about the risks of SQL injection and ensure secure development lifecycle practices are followed for future updates. 9) Backup databases regularly and verify restoration procedures to minimize impact in case of data tampering. 10) Engage with the vendor or community to obtain or develop official patches or updates.
