CVE-2019-25473 in Clinic Pro
Summary
by MITRE • 03/12/2026
Clinic Pro contains a SQL injection vulnerability that allows authenticated attackers to manipulate database queries by injecting SQL code through the month parameter. Attackers can send POST requests to the monthly_expense_overview endpoint with crafted month values using boolean-based blind, time-based blind, or error-based SQL injection techniques to extract sensitive database information.

The vulnerability identified as CVE-2019-25473 represents a critical SQL injection flaw within the Clinic Pro application that fundamentally compromises database security through improper input validation. This vulnerability exists in the monthly_expense_overview endpoint where the application fails to adequately sanitize user-supplied data, specifically the month parameter that users can manipulate through authenticated POST requests. The flaw allows malicious actors to inject arbitrary SQL code into database queries, potentially enabling complete database compromise and unauthorized access to sensitive patient and financial information.
The technical implementation of this vulnerability stems from the application's failure to employ proper parameterized queries or input sanitization mechanisms when processing the month parameter. Attackers can leverage this weakness through three primary SQL injection techniques: boolean-based blind injection where the application's response varies based on boolean conditions, time-based blind injection that relies on query execution delays to infer information, and error-based injection that forces the database to return error messages containing sensitive data. These methods collectively enable attackers to systematically extract database schemas, user credentials, and confidential medical records without requiring advanced technical skills beyond basic web exploitation knowledge.
The operational impact of this vulnerability extends beyond simple data theft to encompass potential regulatory violations under healthcare privacy laws such as HIPAA and GDPR, as the compromised data includes sensitive patient medical information and financial records. Organizations utilizing Clinic Pro software face significant risk of data breaches, regulatory fines, and reputational damage when this vulnerability remains unpatched. The authenticated nature of the attack means that adversaries must first obtain valid user credentials, but once achieved, they can execute sophisticated data exfiltration campaigns without detection, as the injected SQL queries may appear legitimate to standard security monitoring systems. This vulnerability directly maps to CWE-89 which categorizes SQL injection as a fundamental weakness in input validation and data handling.
Mitigation strategies for CVE-2019-25473 require immediate implementation of proper input validation and parameterized query execution throughout the application's data access layers. Organizations should deploy web application firewalls to detect and block malicious SQL injection patterns, implement comprehensive database access controls with least privilege principles, and conduct regular security assessments to identify similar vulnerabilities in other application components. The remediation process must include thorough code review to ensure all database interaction points properly utilize prepared statements or parameterized queries, as recommended by the OWASP Top Ten and NIST cybersecurity guidelines. Additionally, implementing database activity monitoring and intrusion detection systems can help identify potential exploitation attempts and provide early warning of unauthorized database access patterns that may indicate successful exploitation of this vulnerability.
