CVE-2025-65340: Hospital Management System SQL Injection

CVE-2025-65340 Overview

CVE-2025-65340 is a SQL Injection vulnerability affecting kishan0725 Hospital Management System version 4.0. The flaw resides in the /betweendates-detailsreports.php endpoint, where the fromdate parameter is passed to database queries without proper sanitization. An attacker can inject malicious SQL statements through this parameter to manipulate backend query logic. Public analysis using sqlmap has confirmed exploitability of the injection point. The vulnerability enables unauthorized access to hospital records, patient data, and administrative content stored in the underlying MySQL database.

Critical Impact
Attackers can extract, modify, or delete sensitive patient and administrative data by injecting crafted SQL payloads into the fromdate parameter of betweendates-detailsreports.php.

Affected Products

kishan0725 Hospital Management System 4.0
The betweendates-detailsreports.php reporting component
Deployments using the vulnerable fromdate request parameter

Technical Details for CVE-2025-65340

Vulnerability Analysis

The vulnerability is a classic SQL Injection flaw in the Hospital Management System reporting module. The script betweendates-detailsreports.php accepts a fromdate parameter used to filter records between two dates. Analysis performed with sqlmap, as documented in the TaintRadar research repository, confirms that this parameter is concatenated directly into a SQL query. Injection techniques identified include boolean-based blind, time-based blind, and UNION-based queries against the underlying MySQL database. Successful exploitation returns arbitrary data from any table the application user can reach.

Root Cause

The root cause is the absence of parameterized queries and input validation on the fromdate field. The application concatenates user-controlled input directly into a SQL statement. Because the input is not cast to a date type or bound as a prepared statement parameter, injected SQL syntax executes with the privileges of the database account used by the PHP application.

Attack Vector

An attacker submits a crafted HTTP request containing SQL syntax in the fromdate parameter to /betweendates-detailsreports.php. Depending on authentication requirements of the deployment, this may be exploitable pre- or post-authentication. Automated tools such as sqlmap can enumerate databases, tables, and records by iterating boolean and time-based payloads. Refer to the GitHub SQL Injection Analysis for the reproduction payloads and technique breakdown.

No verified proof-of-concept code is included here. See the linked technical reference for full request captures and injection payload examples.

Detection Methods for CVE-2025-65340

Indicators of Compromise

HTTP requests to /betweendates-detailsreports.php containing SQL keywords such as UNION, SELECT, SLEEP, or AND 1=1 in the fromdate parameter.
Unusual User-Agent strings associated with sqlmap or other automated injection tools.
Anomalous spikes in database query duration correlated with requests to the reporting endpoint.
Web server logs showing repeated malformed date values in the fromdate query string.

Detection Strategies

Deploy web application firewall (WAF) signatures that block SQL metacharacters in date-typed parameters.
Enable database query logging and alert on queries containing injected boolean tautologies or UNION SELECT patterns.
Correlate web access logs with database audit logs to identify requests that produce unexpectedly large result sets.
Perform authenticated dynamic application security testing (DAST) scans of the Hospital Management System with sqlmap or equivalent tools.

Monitoring Recommendations

Monitor HTTP 200 responses to /betweendates-detailsreports.php that return abnormally large payloads.
Track outbound data transfer volumes from the web server to detect bulk data exfiltration.
Alert on new database users, altered privileges, or unexpected INFORMATION_SCHEMA queries originating from the application account.

How to Mitigate CVE-2025-65340

Immediate Actions Required

Restrict access to /betweendates-detailsreports.php to authenticated administrative users only, ideally behind a VPN or IP allowlist.
Deploy a WAF rule set that rejects SQL metacharacters and non-date content in the fromdate and related report parameters.
Rotate database credentials used by the application and reduce the database account privileges to the minimum required.
Review database audit logs for evidence of prior exploitation attempts against the reporting endpoint.

Patch Information

At the time of publication, no vendor patch has been referenced in the NVD entry for kishan0725 Hospital Management System 4.0. Operators should track the upstream project repository for fixes and, in the interim, apply source-level remediation by converting the vulnerable query to a prepared statement with bound parameters. Input to fromdate and todate should be validated against a strict date format such as YYYY-MM-DD before being used in any query.

Workarounds

Rewrite the vulnerable query in betweendates-detailsreports.php using mysqli or PDO prepared statements with typed bindings.
Enforce server-side validation that rejects any fromdate value not matching a strict date regular expression.
Disable or remove the reporting endpoint if it is not required for production operations.
Isolate the application database on a segmented network and disable the FILE privilege for the application user.

bash

# Configuration example: strict input validation in PHP before query execution
$fromdate = $_POST['fromdate'] ?? '';
if (!preg_match('/^\d{4}-\d{2}-\d{2}$/', $fromdate)) {
    http_response_code(400);
    exit('Invalid date format');
}
$stmt = $pdo->prepare('SELECT * FROM appointment WHERE date BETWEEN :fromdate AND :todate');
$stmt->execute([':fromdate' => $fromdate, ':todate' => $todate]);
