CVE-2024-5051: Gas Agency Management System SQLi Flaw

CVE-2024-5051 Overview

CVE-2024-5051 is a SQL injection vulnerability in SourceCodester Gas Agency Management System 1.0. The flaw resides in edituser.php, where the id parameter is passed to a backend SQL query without proper sanitization. Attackers can manipulate this argument remotely to inject arbitrary SQL statements. The exploit has been publicly disclosed and may be used against exposed instances. The vulnerability is tracked as VulDB entry 264748 and maps to CWE-89: Improper Neutralization of Special Elements used in an SQL Command.

Critical Impact
Authenticated remote attackers can inject SQL through the id parameter in edituser.php, enabling unauthorized read and modification of the application database.

Affected Products

Mayurik (SourceCodester) Gas Agency Management System 1.0
Deployments using the vulnerable edituser.php endpoint
Web servers hosting unpatched instances reachable over the network

Technical Details for CVE-2024-5051

Vulnerability Analysis

The vulnerability is a SQL injection flaw in the edituser.php script of the Gas Agency Management System. The application accepts an id parameter from user-controlled input and concatenates it into a SQL query without parameterization or escaping. An attacker with low-privilege access to the application can supply crafted values that alter the intended query. The application processes the manipulated statement as if it were legitimate.

Successful injection allows an attacker to enumerate database contents, retrieve user credentials, and modify records. The attack can be launched over the network without user interaction. Because the exploit is publicly documented on GitHub, opportunistic exploitation against exposed installations is plausible.

Root Cause

The root cause is missing input validation and lack of prepared statements in the edituser.php handler. The id argument flows directly into a SQL string built via concatenation. No allow-list, type check, or parameter binding is applied before query execution.

Attack Vector

An authenticated attacker sends an HTTP request to edituser.php with a malicious id value. The payload closes the original query context and appends attacker-controlled SQL clauses such as UNION SELECT or boolean-based tests. See the public proof-of-concept documentation and VulDB entry 264748 for further technical detail.

Detection Methods for CVE-2024-5051

Indicators of Compromise

HTTP requests to edituser.php containing SQL metacharacters such as ', --, UNION, or SLEEP( in the id parameter
Web server access logs showing repeated requests to edituser.php with numeric-then-alphanumeric transitions in the id value
Unexpected database errors referencing the edituser.php endpoint in application logs

Detection Strategies

Deploy a web application firewall rule that inspects query and body parameters to edituser.php for SQL injection signatures
Enable database query logging and alert on unions, subqueries, or timing functions originating from the application user
Correlate spikes in 500-level responses from edituser.php with successive parameter mutations from a single client

Monitoring Recommendations

Forward web server, application, and database logs to a centralized analytics platform for cross-source correlation
Baseline normal edituser.php traffic volume and alert on deviations in request rate, parameter length, or user-agent diversity
Monitor egress traffic from the database host for signs of exfiltration following suspicious requests

How to Mitigate CVE-2024-5051

Immediate Actions Required

Restrict access to the Gas Agency Management System to trusted networks or a VPN until a fix is applied
Audit edituser.php and replace string concatenation with parameterized queries or prepared statements
Review database accounts used by the application and enforce least privilege on schemas the application does not need to modify

Patch Information

No vendor patch or fixed release has been published for SourceCodester Gas Agency Management System 1.0 at the time of writing. Operators should treat the application as unmaintained and evaluate replacement or in-house remediation. Monitor VulDB 264748 for updates.

Workarounds

Add server-side input validation that constrains the id parameter to a strict integer type before it reaches any SQL context
Deploy WAF signatures that block common SQL injection payloads targeting edituser.php
Rotate database credentials and application session secrets if exploitation is suspected

bash

# Example nginx rule to block obvious SQLi patterns against edituser.php
location = /edituser.php {
    if ($args ~* "(union|select|sleep|--|';|/\*)") {
        return 403;
    }
    proxy_pass http://backend;
