code-projects Online Hospital Management System SQL Injection Vulnerability

CVE-2026-7632 is a critical security flaw affecting code-projects Online Hospital Management System version 1.0. The vulnerability lies within the /viewappointment.php file, where insufficient input validation allows for SQL injection via the delid argument. A remote attacker can exploit this vulnerability to inject arbitrary SQL queries, potentially leading to unauthorized data access, modification, or deletion. The exploit is publicly disclosed, increasing the risk of widespread exploitation. This vulnerability poses a significant threat to organizations using the affected system, as it could compromise sensitive patient data and disrupt hospital operations.

Attack Chain

1. The attacker identifies an instance of code-projects Online Hospital Management System 1.0 running the vulnerable /viewappointment.php script.
2. The attacker crafts a malicious HTTP request targeting /viewappointment.php with a specially crafted delid parameter containing SQL injection payloads.
3. The application fails to properly sanitize the delid input, allowing the injected SQL code to be passed to the database.
4. The injected SQL code is executed against the database server.
5. The attacker retrieves sensitive data such as patient records, usernames, and passwords from the database using SQL queries like UNION SELECT.
6. The attacker may modify or delete data within the database.
7. The attacker could potentially escalate privileges within the application by manipulating user roles or injecting administrative accounts.

Impact

Successful exploitation of CVE-2026-7632 can lead to severe consequences, including unauthorized access to sensitive patient data, such as medical history, personal information, and financial records. Attackers could modify or delete critical data, disrupting hospital operations and potentially impacting patient care. The vulnerability could also allow attackers to gain control of the system, leading to further malicious activities like data exfiltration or ransomware deployment. This poses a significant risk to the privacy and security of patient information.

Recommendation

• Deploy the Sigma rule Detect SQL Injection in Online Hospital Management System to your SIEM to identify exploitation attempts targeting the /viewappointment.php endpoint.
• Implement input validation and sanitization measures in the /viewappointment.php script to prevent SQL injection attacks.
• Upgrade to a patched version of code-projects Online Hospital Management System that addresses CVE-2026-7632 (if available).
