CVE-2025-9829 is a SQL Injection vulnerability identified in version 1.1 of the PHPGurukul Beauty Parlour Management System, specifically within the /signup.php file. The vulnerability arises from improper sanitization or validation of the 'mobilenumber' parameter, which allows an attacker to inject malicious SQL code. This injection can be exploited remotely without any authentication or user interaction, as indicated by the CVSS vector (AV:N/AC:L/AT:N/UI:N/PR:N). The vulnerability impacts the confidentiality, integrity, and availability of the underlying database, potentially allowing attackers to read, modify, or delete sensitive data stored by the application. Although the exact function affected is unknown, the presence of an exploitable SQL injection in a signup module suggests that user registration or authentication data could be compromised. Other parameters may also be vulnerable, increasing the attack surface. The CVSS 4.0 base score of 6.9 (medium severity) reflects the ease of exploitation combined with limited scope and impact. No patches or fixes have been published yet, and no known exploits are currently observed in the wild, but public exploit code availability increases the risk of exploitation. This vulnerability is critical for organizations using this specific management system, especially those handling customer personal data and payment information, as it could lead to data breaches, unauthorized access, and service disruption.

For European organizations using the PHPGurukul Beauty Parlour Management System 1.1, this vulnerability poses a significant risk to customer data privacy and business operations. Exploitation could lead to unauthorized access to personally identifiable information (PII), including mobile numbers and potentially other sensitive registration data. This could result in GDPR violations with substantial fines and reputational damage. Additionally, attackers could manipulate or delete database records, disrupting business continuity and customer trust. Since the vulnerability allows remote exploitation without authentication, attackers can target exposed web servers directly. This is particularly concerning for small and medium-sized enterprises (SMEs) in the beauty and wellness sector, which may lack robust cybersecurity defenses. The availability of public exploit code increases the likelihood of opportunistic attacks. The vulnerability could also be leveraged as a foothold for further network intrusion or lateral movement within an organization’s infrastructure.

1. Immediate mitigation should include restricting external access to the /signup.php endpoint via web application firewalls (WAFs) or network access controls to limit exposure. 2. Implement input validation and parameterized queries (prepared statements) in the signup module to prevent SQL injection. 3. Conduct a comprehensive code review of all input handling in the application, especially other parameters that might be vulnerable. 4. Monitor web server and database logs for suspicious queries or unusual activity targeting the 'mobilenumber' parameter or signup functionality. 5. If possible, upgrade to a patched version once available or consider migrating to alternative management systems with better security track records. 6. Educate staff about the risks and ensure regular backups of databases to enable recovery in case of data tampering. 7. Deploy runtime application self-protection (RASP) tools to detect and block injection attempts in real time. 8. For organizations unable to patch immediately, consider deploying virtual patching rules on WAFs to block known exploit patterns.
