The vulnerability identified as CVE-2024-44641 affects PHPGurukul Small CRM version 3.0, a customer relationship management software commonly used by small and medium enterprises. The issue lies in the change-password.php script, where the 'oldpass' parameter is susceptible to SQL Injection attacks. SQL Injection occurs when untrusted input is concatenated directly into SQL queries without proper sanitization or parameterization, allowing attackers to manipulate the database queries executed by the application. In this case, an attacker can craft malicious input to the 'oldpass' parameter to execute arbitrary SQL commands. This can lead to unauthorized data access, modification, or deletion, potentially compromising user credentials and sensitive CRM data. The vulnerability does not require prior authentication or user interaction, making it easier for remote attackers to exploit. No official patches or fixes have been published yet, and no known exploits have been observed in the wild. However, the presence of this vulnerability in a CRM system that stores critical business and customer data elevates the risk. The lack of a CVSS score necessitates an independent severity assessment based on impact and exploitability factors.

For European organizations, exploitation of this SQL Injection vulnerability could result in unauthorized access to confidential customer data, including personal and financial information, leading to data breaches and regulatory non-compliance under GDPR. Attackers could alter or delete CRM data, disrupting business operations and damaging trust with clients. The vulnerability could also be leveraged as a foothold for further network compromise or lateral movement within corporate environments. Small and medium enterprises, which are the primary users of PHPGurukul Small CRM, may lack advanced security monitoring, increasing their risk exposure. The potential for data loss and reputational damage is significant, especially for companies handling sensitive or regulated data. Additionally, the absence of known exploits currently provides a window for proactive mitigation before widespread attacks occur.

Organizations using PHPGurukul Small CRM 3.0 should immediately audit the change-password.php script and any other input-handling code for SQL Injection vulnerabilities. Developers must implement parameterized queries or prepared statements to safely handle user inputs, particularly the 'oldpass' parameter. Input validation and sanitization should be enforced to reject malicious payloads. If source code modification is not immediately feasible, deploying Web Application Firewalls (WAFs) with SQL Injection detection rules can provide temporary protection. Monitoring logs for unusual database query patterns or failed login attempts can help detect exploitation attempts. Organizations should also review user privileges in the database to minimize damage in case of compromise. Finally, contacting the software vendor or community for patches or updates is critical, and applying any available fixes promptly is essential to secure the environment.
