CVE-2024-9318: Advocate Office Management SQL Injection

CVE-2024-9318 Overview

CVE-2024-9318 is a SQL injection vulnerability in SourceCodester Advocate Office Management System 1.0, developed by Mayurik. The flaw resides in the /control/activate.php script, where the id parameter is passed directly into a SQL query without sanitization. Authenticated remote attackers can manipulate the parameter to inject arbitrary SQL statements. The exploit details have been publicly disclosed, increasing the risk of opportunistic abuse against exposed instances.

Critical Impact

Remote attackers with low-level privileges can extract, modify, or destroy database contents through error-based SQL injection in the activate.php endpoint.

Affected Products

• Mayurik Advocate Office Management System 1.0
• SourceCodester Advocate Office Management System 1.0
• /control/activate.php component (id parameter)

Technical Details for CVE-2024-9318

Vulnerability Analysis

The vulnerability is an error-based SQL injection [CWE-89] in the activation workflow of the Advocate Office Management System. The application accepts the id parameter through /control/activate.php and concatenates the value into a SQL statement without parameterization or input validation. An attacker can append SQL operators, UNION clauses, or boolean conditions to retrieve data from the underlying database.

Because the application surfaces database errors to the client, attackers can use error-based techniques to enumerate schema names, table structures, and column data. The vulnerability requires network access to the web interface and low-privilege authentication. The disclosed proof-of-concept makes weaponization trivial for attackers with access to the application.

Root Cause

The root cause is improper neutralization of special elements in a SQL command. The activate.php script builds queries through string concatenation using user-supplied input. No prepared statements, stored procedures, or input filtering protect the id parameter before it reaches the database layer.

Attack Vector

An authenticated attacker sends a crafted HTTP request to /control/activate.php with a malicious id parameter. Payloads using single quotes, comments, or UNION SELECT statements alter query logic. Successful exploitation enables information disclosure, data tampering, and possible authentication bypass through manipulation of activation records. Refer to the GitHub SQL Injection Vulnerability advisory for the disclosed payload structure.

Detection Methods for CVE-2024-9318

Indicators of Compromise

• HTTP requests to /control/activate.php containing SQL metacharacters such as ', --, /*, UNION, SELECT, or SLEEP in the id parameter.
• Database error messages returned in HTTP responses originating from the activation endpoint.
• Spikes in 500 or 200 responses from activate.php correlated with unusual id parameter lengths.
• Unexpected reads against sensitive tables logged by the MySQL/MariaDB query log.

Detection Strategies

• Deploy web application firewall rules that flag SQL injection signatures against the activate.php URI path.
• Inspect access logs for sequential probing of the id parameter with incrementing or alphanumeric payloads.
• Correlate database error events with the originating web session to identify exploitation chains.

Monitoring Recommendations

• Enable verbose logging on the database layer to record query failures and suspicious UNION-based reads.
• Forward web server and database logs to a centralized analytics platform for correlation and retention.
• Alert on authenticated sessions issuing repeated requests to /control/activate.php within short time windows.

How to Mitigate CVE-2024-9318

Immediate Actions Required

• Restrict network exposure of the Advocate Office Management System to trusted networks or VPN access until a fix is deployed.
• Audit the activate.php source code and replace string-concatenated queries with parameterized statements.
• Rotate database credentials and review user accounts for unauthorized modifications.
• Review web server access logs for prior exploitation attempts targeting the id parameter.

Patch Information

At the time of publication, no vendor patch is listed in the NVD entry for CVE-2024-9318. Organizations running the Advocate Office Management System 1.0 should contact Mayurik through the SourceCodester Resource Hub for remediation guidance and monitor the VulDB advisory for updates.

Workarounds

• Apply WAF rules that block SQL injection payloads on the /control/activate.php endpoint.
• Enforce input validation at the reverse proxy layer to reject non-numeric values for the id parameter.
• Limit database user privileges so the web application account cannot read or alter sensitive tables.
• Disable verbose error reporting in PHP to prevent leakage of SQL error messages to clients.

# Example nginx configuration to block suspicious id parameters
location /control/activate.php {
    if ($arg_id ~* "(union|select|sleep|--|/\*|')") {
        return 403;
    }
    proxy_pass http://backend;
