CVE-2025-6777: Food Distributor Site SQLi Vulnerability

CVE-2025-6777 Overview

A SQL Injection vulnerability has been identified in code-projects Food Distributor Site version 1.0. This critical flaw exists in the file /admin/process_login.php where the username and password parameters are not properly sanitized before being used in SQL queries. The vulnerability allows remote attackers to inject malicious SQL code, potentially compromising the entire database and gaining unauthorized access to the administrative panel.

Critical Impact

Attackers can remotely exploit this SQL injection vulnerability without authentication, potentially gaining full access to the database, extracting sensitive information, modifying data, or bypassing authentication mechanisms entirely.

Affected Products

• Fabian Food Distributor Site version 1.0
• code-projects Food Distributor Site 1.0

Technical Details for CVE-2025-6777

Vulnerability Analysis

This vulnerability represents a classic SQL Injection flaw (CWE-89) stemming from inadequate input validation (CWE-74) in the administrative login functionality. The /admin/process_login.php file accepts user-supplied input through the username and password parameters and incorporates them directly into SQL queries without proper sanitization or parameterization.

When user input is concatenated directly into SQL statements, attackers can craft malicious payloads that alter the intended query logic. This enables authentication bypass, data extraction through UNION-based attacks, or even database manipulation through stacked queries depending on the underlying database configuration.

The exploit has been publicly disclosed, increasing the risk of widespread exploitation. Organizations running this software should treat this as an urgent security concern requiring immediate attention.

Root Cause

The root cause of this vulnerability is the improper handling of user input in the authentication mechanism. The application fails to implement prepared statements or parameterized queries when processing login credentials. Instead, user-supplied values for username and password are directly interpolated into SQL query strings, creating an injection point that attackers can exploit to manipulate database queries.

Attack Vector

The attack can be initiated remotely over the network without requiring any prior authentication or user interaction. An attacker can target the /admin/process_login.php endpoint by submitting specially crafted values in the username or password fields of the login form.

A typical SQL injection attack against this endpoint would involve inserting SQL metacharacters and query fragments into the login parameters. For example, an attacker might submit a username containing SQL syntax designed to always evaluate as true, effectively bypassing the authentication check. More sophisticated attacks could leverage UNION statements to extract data from other database tables or use time-based blind injection techniques to enumerate database contents.

Detection Methods for CVE-2025-6777

Indicators of Compromise

• Unusual login attempts to /admin/process_login.php containing SQL syntax characters such as single quotes, double dashes, or semicolons
• Database error messages appearing in application logs indicating malformed SQL queries
• Unexpected administrative access from unfamiliar IP addresses or geolocations
• Evidence of data exfiltration or unauthorized database queries in database audit logs

Detection Strategies

• Deploy Web Application Firewall (WAF) rules to detect and block SQL injection patterns in POST parameters targeting authentication endpoints
• Implement application-level logging to capture and alert on login attempts containing suspicious characters or patterns
• Monitor database query logs for anomalous query patterns, particularly those involving UNION statements or conditional logic manipulation
• Configure intrusion detection systems to flag requests to /admin/process_login.php with payload signatures indicative of SQL injection

Monitoring Recommendations

• Enable detailed access logging for the /admin/ directory and review logs regularly for suspicious activity
• Implement real-time alerting for multiple failed authentication attempts followed by successful login
• Monitor database connection patterns for unusual query volumes or access to sensitive tables
• Track administrative panel access patterns and alert on deviations from normal behavior

How to Mitigate CVE-2025-6777

Immediate Actions Required

• Restrict access to the /admin/ directory through IP whitelisting or VPN-only access until a patch is applied
• Implement a Web Application Firewall with SQL injection protection rules in front of the application
• Disable or remove the Food Distributor Site application if it is not critical to operations
• Audit database access logs for evidence of prior exploitation

Patch Information

At the time of publication, no official vendor patch has been released for this vulnerability. Organizations using Food Distributor Site 1.0 should monitor the Code Projects website for security updates. Additional vulnerability details are available through VulDB.

Given the public disclosure of this vulnerability and absence of an official fix, organizations should strongly consider implementing the workarounds below or discontinuing use of the affected software.

Workarounds

• Place the application behind a Web Application Firewall configured to block SQL injection attempts
• Implement network-level access controls to restrict access to the administrative interface to trusted IP addresses only
• Modify the /admin/process_login.php file to use prepared statements with parameterized queries if source code access is available
• Add input validation to reject login attempts containing SQL metacharacters as a temporary measure

# Example: Restrict admin access via Apache .htaccess
# Place in /admin/.htaccess
<RequireAll>
    Require ip 192.168.1.0/24
    Require ip 10.0.0.0/8
</RequireAll>

# Alternatively, disable the vulnerable endpoint temporarily
# Add to Apache configuration or .htaccess
<Files "process_login.php">
    Require all denied
</Files>
