CVE-2024-3226: Campcodes Patient Record System SQL Vuln

CVE-2024-3226 Overview

CVE-2024-3226 is a SQL injection vulnerability in Campcodes Online Patient Record Management System version 1.0. The flaw resides in the /admin/login.php endpoint, where the password parameter is concatenated into a SQL query without proper sanitization. Remote attackers can exploit this issue without authentication or user interaction by submitting crafted input through the login form. Public exploit details have been disclosed, increasing the likelihood of opportunistic attacks against exposed instances. The weakness is tracked under [CWE-89] and assigned VulDB identifier VDB-259071.

Critical Impact
Unauthenticated remote attackers can manipulate backend SQL queries through the admin login form, potentially exposing patient records and administrative credentials.

Affected Products

Technical Details for CVE-2024-3226

Vulnerability Analysis

The vulnerability exists in the administrative authentication handler at /admin/login.php. The application accepts user-supplied input through the password parameter and incorporates it directly into a SQL statement. Because the input is not parameterized or sanitized, attackers can inject SQL syntax that alters the original query logic.

Successful exploitation can bypass authentication and disclose data stored in the application database. The application handles patient records, so an attacker can read protected health information, administrator hashes, and other sensitive content. The vulnerability is reachable remotely over the network and requires no privileges or user interaction.

The public disclosure includes proof-of-concept payloads, lowering the technical barrier for exploitation. Automated scanners and credential-stuffing tools can adapt these payloads to identify vulnerable deployments at scale.

Root Cause

The root cause is improper neutralization of special elements used in a SQL command [CWE-89]. The login handler builds the authentication query using string concatenation rather than prepared statements with bound parameters. Input validation is absent or insufficient on the password field, so SQL metacharacters such as single quotes, comments, and boolean operators reach the database engine intact.

Attack Vector

An attacker sends an HTTP POST request to /admin/login.php containing a crafted password value. Typical payloads use boolean-based or union-based SQL injection techniques to bypass the authentication check or extract data through error messages and conditional responses. The attack requires only network access to the application and a standard HTTP client.

The vulnerability mechanism is documented in the public GitHub Vulnerability Report and the VulDB CVE Analysis. No verified exploit code is reproduced here.

Detection Methods for CVE-2024-3226

Indicators of Compromise

POST requests to /admin/login.php containing SQL metacharacters such as ', --, UNION, OR 1=1, or SLEEP( in the password field
Repeated authentication failures from the same source IP followed by a successful login
Database error messages returned to clients during login attempts
Unexpected administrative sessions originating from external IP ranges

Detection Strategies

Inspect web server access logs for anomalous payloads targeting the password parameter on the admin login endpoint
Deploy a web application firewall with SQL injection signatures tuned for login endpoints
Enable database query logging and alert on UNION SELECT or time-delay functions originating from the application user

Monitoring Recommendations

Forward web server and database logs to a centralized SIEM for correlation
Alert on authentication anomalies, including impossible-travel logins and admin sessions from new geographies
Monitor outbound connections from the database host that could indicate post-exploitation data exfiltration

How to Mitigate CVE-2024-3226

Immediate Actions Required

Restrict access to /admin/login.php using network ACLs, VPN, or IP allowlisting until a patch is applied
Place the application behind a web application firewall with SQL injection rules enabled in blocking mode
Rotate all administrative credentials and review database accounts for unauthorized changes
Audit recent access logs for signs of exploitation against the login endpoint

Patch Information

No vendor patch is referenced in the NVD entry at the time of publication. Operators should monitor Campcodes channels for an updated release and review the VulDB entry for remediation updates. If no fix is available, organizations should evaluate whether the application can be replaced or isolated.

Workarounds

Modify the login handler to use parameterized queries or prepared statements for all database access
Apply server-side input validation that rejects SQL metacharacters in authentication fields
Run the application database account with least-privilege permissions to limit data exposure during exploitation
Disable detailed database error messages in production responses to reduce information leakage

bash

# Example: block direct external access to the admin login at the reverse proxy
location /admin/login.php {
    allow 10.0.0.0/8;
    deny all;
}
