CVE-2025-11507 identifies a SQL injection vulnerability in the PHPGurukul Beauty Parlour Management System version 1.1. The vulnerability exists in the /admin/search-invoices.php script, where the 'searchdata' parameter is not properly sanitized before being used in SQL queries. This allows an unauthenticated remote attacker to manipulate the SQL query logic by injecting crafted input, potentially leading to unauthorized data access, data modification, or database compromise. The vulnerability requires no authentication or user interaction, making it easily exploitable over the network. The CVSS 4.0 vector (AV:N/AC:L/AT:N/PR:N/UI:N/VC:L/VI:L/VA:L/SC:N/SI:N/SA:N/E:P) indicates network attack vector, low attack complexity, no privileges or user interaction needed, and partial impacts on confidentiality, integrity, and availability. Although the impact is partial, the exploitability and public availability of exploit code increase the threat level. No official patches or mitigations have been released by the vendor as of the publication date. The vulnerability affects only version 1.1 of the product, which is a niche management system used primarily by small and medium beauty parlour businesses. The lack of segmentation or hardened access controls in typical deployments may exacerbate the risk. This vulnerability is a classic example of improper input validation leading to SQL injection, a common and dangerous web application security flaw.

The SQL injection vulnerability allows attackers to execute arbitrary SQL commands on the backend database, potentially leading to unauthorized disclosure of sensitive customer and business data, data tampering, or deletion. This can compromise the confidentiality, integrity, and availability of the affected system. For organizations, this could result in data breaches involving client personal information, financial records, and transaction histories, damaging reputation and incurring regulatory penalties. Attackers could also leverage this vulnerability to pivot further into internal networks if the management system is connected to broader IT infrastructure. Since the vulnerability requires no authentication or user interaction, it is highly accessible to remote attackers scanning for vulnerable instances. The public availability of exploit code increases the likelihood of opportunistic attacks, especially targeting small businesses that may lack robust cybersecurity defenses. The impact is particularly significant for businesses relying on this system for daily operations, as disruption or data loss could affect service continuity and customer trust.

1. Immediately restrict access to the /admin/search-invoices.php endpoint by IP whitelisting or VPN-only access to reduce exposure. 2. Implement strict input validation and sanitization on the 'searchdata' parameter, ensuring that only expected input formats are accepted. 3. Refactor the code to use parameterized queries or prepared statements to prevent SQL injection. 4. Conduct a thorough security review of the entire application to identify and remediate similar injection flaws. 5. Monitor logs for suspicious query patterns or repeated failed attempts indicative of exploitation attempts. 6. If possible, isolate the database with least privilege principles, ensuring the web application user has minimal rights. 7. Backup all critical data regularly to enable recovery in case of compromise. 8. Engage with the vendor or community to obtain or develop patches and apply them promptly once available. 9. Educate staff on the risks and signs of exploitation to improve detection and response. 10. Consider deploying web application firewalls (WAFs) with SQL injection detection rules as an interim protective measure.
