CVE-2025-10079 is a SQL Injection vulnerability identified in version 4.0 of PHPGurukul Small CRM, specifically within the /get-quote.php file. The vulnerability arises from improper sanitization or validation of the 'Contact' parameter, which allows an attacker to manipulate SQL queries executed by the application. This flaw enables remote attackers to inject malicious SQL code without requiring authentication or user interaction, potentially leading to unauthorized data access, data modification, or disruption of database operations. The vulnerability has a CVSS 4.0 base score of 6.9, indicating a medium severity level, with an attack vector of network (remote), low attack complexity, and no privileges or user interaction required. The impact on confidentiality, integrity, and availability is rated as low individually but combined can lead to significant compromise of the CRM's database. Although no known exploits are currently observed in the wild, the public disclosure and availability of exploit code increase the risk of exploitation. The vulnerability affects only version 4.0 of the Small CRM product by PHPGurukul, which is a customer relationship management tool likely used by small to medium enterprises for managing client data and interactions.

For European organizations using PHPGurukul Small CRM 4.0, this vulnerability poses a risk of unauthorized access to sensitive customer and business data stored within the CRM database. Exploitation could lead to data breaches involving personal identifiable information (PII), business contact details, and potentially financial information, impacting GDPR compliance and resulting in legal and reputational consequences. The ability to manipulate SQL queries remotely without authentication means attackers can extract, modify, or delete critical data, disrupting business operations and customer management workflows. This could also facilitate further attacks such as privilege escalation or lateral movement within the network if the CRM database is integrated with other systems. The medium severity rating suggests that while the vulnerability is serious, it may require some technical skill to exploit effectively. However, the lack of required privileges or user interaction lowers the barrier for attackers. Organizations relying on this CRM for client management should consider the potential operational and compliance impacts, especially in sectors with stringent data protection requirements such as finance, healthcare, and public services.

1. Immediate upgrade or patching: Organizations should check for any official patches or updates from PHPGurukul addressing this vulnerability. If no patch is available, consider upgrading to a newer, unaffected version of the Small CRM product. 2. Input validation and sanitization: Implement strict input validation on the 'Contact' parameter to ensure only expected data types and formats are accepted. Use parameterized queries or prepared statements to prevent SQL injection. 3. Web Application Firewall (WAF): Deploy and configure a WAF with rules specifically designed to detect and block SQL injection attempts targeting the /get-quote.php endpoint. 4. Database permissions: Restrict database user permissions used by the CRM application to the minimum necessary, limiting the potential damage from a successful injection. 5. Monitoring and logging: Enable detailed logging of database queries and web application access to detect suspicious activities indicative of SQL injection attempts. 6. Network segmentation: Isolate the CRM system within a secure network segment to limit exposure and lateral movement in case of compromise. 7. Incident response readiness: Prepare and test incident response plans to quickly address any exploitation attempts, including data breach notification procedures compliant with GDPR.
