CVE-2025-11506 identifies a SQL injection vulnerability in PHPGurukul Beauty Parlour Management System version 1.1, specifically in the /admin/search-appointment.php file. The vulnerability arises from improper sanitization of the 'searchdata' parameter, which is directly incorporated into SQL queries without adequate validation or use of prepared statements. This flaw allows an unauthenticated remote attacker to inject arbitrary SQL commands, potentially enabling unauthorized data access, modification, or deletion within the underlying database. The vulnerability requires no user interaction and no privileges, making it remotely exploitable over the network. The CVSS 4.0 vector indicates network attack vector (AV:N), low attack complexity (AC:L), no authentication (AT:N), and no user interaction (UI:N), with limited impact on confidentiality, integrity, and availability (VC:L, VI:L, VA:L). Although no known exploits are currently active in the wild, the public release of exploit code increases the likelihood of exploitation attempts. The affected product is a niche PHP-based management system targeted at beauty parlours, which may limit the scale of impact but still poses a risk to organizations relying on this software for appointment and customer data management. The lack of available patches or vendor advisories necessitates immediate mitigation by users. This vulnerability exemplifies common risks in web applications that fail to properly sanitize user inputs, underscoring the importance of secure coding practices such as parameterized queries and input validation.

For European organizations using PHPGurukul Beauty Parlour Management System 1.1, this vulnerability could lead to unauthorized access to sensitive customer and appointment data, potentially violating data protection regulations such as GDPR. Attackers could manipulate or exfiltrate data, impacting confidentiality and integrity, and possibly disrupt service availability by executing destructive SQL commands. Given the nature of the affected software—used primarily by small to medium beauty parlour businesses—the impact may be localized but could still result in reputational damage and financial loss. Additionally, compromised systems could be leveraged as footholds for broader network intrusion if attackers gain access to internal networks. The public availability of exploit code increases the risk of opportunistic attacks, especially against organizations lacking robust security monitoring and patch management. European businesses with limited cybersecurity resources are particularly vulnerable. Furthermore, breaches involving personal data could lead to regulatory penalties under GDPR, amplifying the impact beyond technical damage.

Organizations should immediately audit their use of PHPGurukul Beauty Parlour Management System 1.1 and prioritize upgrading or patching the software if updates become available. In the absence of official patches, implement the following mitigations: 1) Apply strict input validation and sanitization on the 'searchdata' parameter, ensuring only expected characters and formats are accepted. 2) Refactor the vulnerable code to use parameterized queries or prepared statements to prevent SQL injection. 3) Restrict access to the /admin/search-appointment.php endpoint via network controls such as IP whitelisting or VPN access to reduce exposure. 4) Monitor database logs and web application logs for suspicious queries or unusual activity indicative of injection attempts. 5) Employ web application firewalls (WAF) with rules targeting SQL injection patterns to provide an additional layer of defense. 6) Conduct security awareness training for administrators to recognize and respond to potential exploitation signs. 7) Regularly back up databases and test restoration procedures to minimize impact from potential data corruption or deletion. These targeted actions go beyond generic advice by focusing on the specific vulnerable parameter and operational context of the affected software.
