CVE-2025-9832: Food Ordering Management System SQL Injection

CVE-2025-9832 Overview

A SQL injection vulnerability has been identified in SourceCodester Food Ordering Management System version 1.0. The vulnerability affects an unknown function within the file /routers/register-router.php. Manipulation of the phone argument allows attackers to perform SQL injection attacks. This vulnerability can be exploited remotely over the network, and the exploit has been publicly disclosed.

Critical Impact

Remote attackers can inject malicious SQL queries through the phone parameter in the registration functionality, potentially leading to unauthorized data access, modification, or deletion of database contents.

Affected Products

Technical Details for CVE-2025-9832

Vulnerability Analysis

This vulnerability stems from improper input validation in the registration functionality of the Food Ordering Management System. The affected endpoint at /routers/register-router.php fails to properly sanitize user-supplied input in the phone parameter before incorporating it into SQL queries. This creates a classic SQL injection condition where an attacker can manipulate the structure of database queries by providing specially crafted input.

The vulnerability is classified under CWE-89 (SQL Injection) and CWE-74 (Improper Neutralization of Special Elements in Output Used by a Downstream Component). The network-accessible nature of this flaw means that any remote attacker can attempt exploitation without requiring prior authentication or user interaction.

Root Cause

The root cause is the lack of proper input sanitization and parameterized queries in the registration router. The application directly concatenates user-supplied phone parameter values into SQL statements without proper escaping or the use of prepared statements. This architectural weakness allows malicious SQL syntax to be interpreted as part of the query structure rather than as literal data.

Attack Vector

The attack can be performed remotely via network access to the vulnerable web application. An attacker targets the /routers/register-router.php endpoint by submitting a crafted HTTP request containing SQL injection payloads in the phone parameter field. No authentication is required to exploit this vulnerability, and no user interaction is necessary for the attack to succeed.

The exploitation methodology typically involves:

1. Identifying the vulnerable registration endpoint
2. Crafting SQL injection payloads for the phone parameter
3. Submitting malicious requests to extract, modify, or delete database information
4. Potentially escalating access to gain administrative privileges within the application

Technical details and proof-of-concept information have been documented in the GitHub Issue Discussion and VulDB entry #322179.

Detection Methods for CVE-2025-9832

Indicators of Compromise

• Unusual or malformed requests to /routers/register-router.php containing SQL syntax characters such as single quotes, double dashes, UNION keywords, or SELECT statements in the phone parameter
• Database error messages exposed in HTTP responses indicating SQL query failures
• Unexpected database queries or access patterns in database logs originating from the web application
• Anomalous registration attempts with phone field values containing non-numeric characters or excessive length

Detection Strategies

• Deploy Web Application Firewall (WAF) rules to detect and block SQL injection patterns in POST parameters targeting the registration endpoint
• Implement application-level logging to capture and alert on requests containing SQL metacharacters in input fields
• Configure database activity monitoring to detect unusual query patterns such as UNION-based or time-based blind SQL injection attempts
• Use intrusion detection systems (IDS) with SQL injection signatures to monitor network traffic to the affected application

Monitoring Recommendations

• Enable verbose logging on the web server and review logs for requests to /routers/register-router.php with suspicious payloads
• Monitor database query logs for unexpected SELECT, UNION, or information_schema queries not associated with normal application behavior
• Set up alerts for multiple failed registration attempts from the same source IP with varying phone parameter values
• Track any unauthorized data exports or modifications to the user registration database tables

How to Mitigate CVE-2025-9832

Immediate Actions Required

• Remove public access to the Food Ordering Management System until a security patch is applied or the vulnerability is remediated
• Implement input validation to restrict the phone parameter to numeric characters and expected length
• Deploy a Web Application Firewall with SQL injection protection rules in front of the vulnerable application
• Review database access logs for signs of prior exploitation and assess potential data compromise

Patch Information

No official vendor patch has been released at this time. The application is distributed via SourceCodester, and users should monitor for updates. Given the public disclosure of this vulnerability, organizations are strongly advised to implement workarounds or consider alternative solutions until a patch becomes available.

For additional technical information, refer to the VulDB entry and the GitHub security research discussion.

Workarounds

• Implement prepared statements with parameterized queries in the /routers/register-router.php file to prevent SQL injection
• Add server-side input validation to sanitize the phone parameter, allowing only digits and standard phone number formatting characters
• Restrict network access to the application using firewall rules or VPN requirements to limit exposure
• Deploy a reverse proxy or WAF configured to filter malicious SQL injection payloads before they reach the application

# Add to modsecurity.conf to block SQL injection attempts
