CVE-2026-19364: Hospital Management System SQLi Flaw

CVE-2026-19364 Overview

CVE-2026-19364 is a SQL injection vulnerability in itsourcecode Hospital Management System 1.0. The flaw resides in the /viewdoctorconsultancycharge.php script, where the delid parameter is passed directly into a database query without sanitization. An authenticated remote attacker can manipulate the delid argument to inject arbitrary SQL statements. The exploit has been publicly disclosed, raising the likelihood of opportunistic use against exposed instances. This weakness is classified under CWE-74 (Improper Neutralization of Special Elements in Output).

Critical Impact
Remote attackers with low privileges can read, modify, or delete patient records stored in the Hospital Management System database by injecting SQL through the delid parameter.

Affected Products

Technical Details for CVE-2026-19364

Vulnerability Analysis

The vulnerability exists in the viewdoctorconsultancycharge.php component of itsourcecode Hospital Management System 1.0. The application concatenates the delid HTTP request parameter into a SQL statement without parameterization or input validation. An attacker submits crafted values through the delid argument to alter the intended query structure. This grants direct read and write access to backend database tables, including patient, doctor, and billing records. Public disclosure of the exploit lowers the technical barrier for opportunistic attackers to reproduce the attack against internet-exposed deployments.

Root Cause

The root cause is improper neutralization of special elements used in a downstream SQL query (CWE-74). The delid parameter is inserted into a query string using direct string concatenation rather than prepared statements. No server-side type checking, whitelist validation, or escaping is applied before the value reaches the database driver.

Attack Vector

Exploitation occurs over the network against the vulnerable PHP endpoint. The attacker requires low-level authenticated access to the application, but no user interaction is needed. A single crafted HTTP request supplying malicious SQL syntax in the delid parameter is sufficient to trigger the injection. Successful exploitation compromises the confidentiality, integrity, and availability of the database.

No verified proof-of-concept code is included in this article. Technical write-ups are available in the GitHub Issue Discussion and the VulDB CVE-2026-19364 entry.

Detection Methods for CVE-2026-19364

Indicators of Compromise

HTTP requests to /viewdoctorconsultancycharge.php containing SQL metacharacters such as single quotes, UNION, SELECT, --, or %27 inside the delid parameter.
Web server access logs showing repeated requests to the affected endpoint from a single source with varying delid values.
Unexpected database errors or long-running queries originating from the Hospital Management System application user.

Detection Strategies

Deploy web application firewall (WAF) rules that inspect the delid query parameter for SQL injection patterns.
Enable database query logging and alert on syntactically malformed queries against tables referenced by viewdoctorconsultancycharge.php.
Correlate authentication events with high-volume access to the vulnerable endpoint to identify credential-abuse attempts.

Monitoring Recommendations

Forward web server, PHP-FPM, and MySQL logs to a centralized SIEM for pattern analysis.
Baseline normal traffic to /viewdoctorconsultancycharge.php and alert on deviations in request volume, source IP diversity, or parameter length.
Monitor for outbound data transfers from the database server that could indicate exfiltration following successful injection.

How to Mitigate CVE-2026-19364

Immediate Actions Required

Restrict network access to the Hospital Management System to trusted internal networks or a VPN until a fix is applied.
Revoke and rotate credentials for any accounts with access to the application, since attacker-supplied SQL may have exfiltrated password hashes.
Audit database contents for unexpected modifications to patient, billing, or user tables.

Patch Information

At the time of publication, no vendor patch has been referenced in the NVD entry for CVE-2026-19364. Refer to the IT Source Code project site and the VulDB Vulnerability #387218 record for future updates. Developers maintaining forks of this codebase should replace vulnerable query construction with parameterized statements using PHP's PDO or mysqli prepared statement APIs.

Workarounds

Add server-side input validation that enforces delid as a strictly numeric value before it reaches any database query.
Deploy a WAF rule blocking SQL metacharacters in the delid parameter of requests to /viewdoctorconsultancycharge.php.
Apply the principle of least privilege to the database account used by the application, removing DROP, ALTER, and cross-database permissions.
