CVE-2025-69943 Overview
CVE-2025-69943 is a SQL Injection vulnerability in kishan0725 Hospital Management System 4.0. The flaw resides in get_doctor.php, where the doctor and specilizationid parameters are concatenated into SQL queries without sanitization. Unauthenticated attackers can send crafted HTTP requests to read, modify, or delete database records containing patient and clinical information. The vulnerability is tracked under CWE-89: Improper Neutralization of Special Elements used in an SQL Command.
Critical Impact
Remote, unauthenticated attackers can extract or manipulate hospital database contents, including protected health information, through crafted requests to get_doctor.php.
Affected Products
- kishan0725 Hospital Management System 4.0
- get_doctor.php endpoint (doctor parameter)
- get_doctor.php endpoint (specilizationid parameter)

Technical Details for CVE-2025-69943
Vulnerability Analysis
The Hospital Management System exposes get_doctor.php to accept two request parameters, doctor and specilizationid. Both values flow directly into a SQL query string executed against the backend database. Because the application does not use prepared statements or input validation, attackers can break out of the intended query context and append arbitrary SQL syntax. This provides read access through UNION SELECT payloads and enables write operations through stacked or conditional queries. Because the endpoint requires no authentication and communicates over standard HTTP, exploitation is straightforward using automated tooling such as sqlmap.
Root Cause
The root cause is unsanitized concatenation of user-controlled parameters into SQL queries within get_doctor.php. The application places the doctor and specilizationid request values into the query body without parameter binding or type enforcement, satisfying the classic conditions for CWE-89.
Attack Vector
An attacker sends an HTTP request to get_doctor.php with a SQL payload supplied through either the doctor or specilizationid parameter. The database evaluates the injected statement and returns data in the HTTP response, enabling boolean-based, union-based, or error-based extraction. Refer to the TaintRadar analysis for the doctor parameter and the TaintRadar analysis for the specilizationid parameter for parameter-level details.

Detection Methods for CVE-2025-69943
Indicators of Compromise
- HTTP requests to get_doctor.php containing SQL metacharacters such as ', --, UNION, SELECT, or SLEEP( in the doctor or specilizationid parameters.
- Web server access logs showing repeated get_doctor.php requests with incrementally changing payloads, indicative of automated tools like sqlmap.
- Database error messages returned in HTTP responses referencing MySQL syntax near injected content.
Detection Strategies
- Deploy a web application firewall (WAF) signature or rule set that flags SQL keywords appearing in query string parameters bound for get_doctor.php.
- Enable database query logging and alert on unusual UNION SELECT statements or queries returning column counts inconsistent with application behavior.
- Correlate authentication logs and web request logs to identify unauthenticated sessions repeatedly querying doctor lookup endpoints.
Monitoring Recommendations
- Monitor for spikes in response size or response time from get_doctor.php, which often accompany data-extraction payloads.
- Track outbound database connections and query volumes originating from the application user context.
- Alert on HTTP 500 responses from the endpoint, which frequently expose SQL error information used to refine injection payloads.
How to Mitigate CVE-2025-69943
Immediate Actions Required
- Restrict internet exposure of the Hospital Management System until the application code is fixed, using network-level access controls or VPN gating.
- Deploy WAF rules that block SQL injection payloads targeting the doctor and specilizationid parameters on get_doctor.php.
- Rotate database credentials used by the application and audit the account's privileges, removing DROP, ALTER, and administrative rights where possible.
Patch Information
No vendor patch is referenced in the NVD entry at the time of publication. Operators should refactor get_doctor.php to use parameterized queries with PDO or mysqli prepared statements, and validate that specilizationid is strictly numeric before use in any query.
Workarounds
- Enforce server-side input validation, rejecting non-integer values for specilizationid and applying an allowlist for doctor.
- Configure the database account used by the application with least-privilege access limited to SELECT on required tables.
- Front the application with a reverse proxy that inspects and normalizes query parameters before forwarding requests to PHP.
# Example ModSecurity rule to block SQL keywords in vulnerable parameters
