CVE-2026-13495: Hospital Management System SQLi Flaw

CVE-2026-13495 Overview

CVE-2026-13495 is a SQL injection vulnerability in itsourcecode Hospital Management System 1.0. The flaw resides in the /adminprofile.php endpoint, where the loginid parameter is passed to a database query without proper sanitization. An authenticated attacker with high privileges can manipulate the parameter to inject arbitrary SQL statements. The exploit has been publicly disclosed, increasing the likelihood of opportunistic attacks. This weakness is classified under [CWE-74] as improper neutralization of special elements in output used by a downstream component.

Critical Impact
Remote attackers with valid administrative credentials can inject SQL statements through the loginid parameter in /adminprofile.php, leading to unauthorized read or modification of hospital records.

Technical Details for CVE-2026-13495

Vulnerability Analysis

The vulnerability affects the administrator profile handler in itsourcecode Hospital Management System 1.0. The /adminprofile.php script accepts a loginid argument from the HTTP request and concatenates it directly into a SQL query. Because the application does not use parameterized statements or input validation, an attacker can append SQL syntax to loginid and alter the query logic. The attack is executed over the network and requires authentication with elevated privileges. Public disclosure of the exploit lowers the barrier for reproduction. The EPSS probability for this CVE stands at 0.214%.

Root Cause

The root cause is improper neutralization of special elements within a database query [CWE-74]. The application concatenates the untrusted loginid value into a SQL statement without prepared statements, parameter binding, or escape routines. Any user-controlled string reaches the SQL parser intact, enabling query manipulation.

Attack Vector

An authenticated attacker sends a crafted HTTP request to /adminprofile.php with a malicious loginid payload. The injected SQL alters the original query to disclose administrator data, modify records, or enumerate the database schema. Exploitation requires an authenticated administrative session but no user interaction. Refer to the VulDB CVE-2026-13495 entry and the GitHub Issue Discussion for reproduction details.

Detection Methods for CVE-2026-13495

Indicators of Compromise

HTTP requests to /adminprofile.php containing SQL meta-characters such as ', --, UNION, or SLEEP( in the loginid parameter.
Web server access logs showing repeated requests to /adminprofile.php with abnormally long or encoded loginid values.
Unexpected database errors or query anomalies in MySQL logs originating from the Hospital Management System user account.

Detection Strategies

Deploy web application firewall signatures that inspect the loginid parameter for SQL injection patterns.
Enable database query logging and alert on statements containing tautologies, UNION SELECT, or stacked queries against admin tables.
Review authentication logs for administrator accounts that generate unusual query volumes shortly after login.

Monitoring Recommendations

Baseline normal request patterns to /adminprofile.php and alert on parameter length or character-set deviations.
Forward web and database logs to a centralized analytics platform for correlation across sessions and source IPs.
Track failed and successful administrative logins to identify credential misuse that could precede exploitation.

How to Mitigate CVE-2026-13495

Immediate Actions Required

Restrict network access to the Hospital Management System administration interface using IP allowlisting or VPN gating.
Rotate administrator credentials and enforce strong, unique passwords for all privileged accounts.
Review recent access logs for /adminprofile.php to identify any prior exploitation attempts.

Patch Information

At the time of publication, no vendor patch has been referenced in the NVD entry. Monitor the IT Source Code project page and the VulDB Vulnerability #374490 record for updates. If the vendor does not issue a fix, modify /adminprofile.php to use parameterized queries with PDO or mysqli prepared statements and validate the loginid input against an expected format.

Workarounds

Place a web application firewall in front of the application and block requests containing SQL syntax in the loginid parameter.
Apply least-privilege principles to the database account used by the application to limit the impact of query manipulation.
Disable or remove the /adminprofile.php endpoint if it is not required for operations.
