CVE-2025-13201 Overview
A SQL Injection vulnerability has been identified in code-projects Simple Cafe Ordering System version 1.0. The vulnerability exists in the /login.php file where the Username argument is not properly sanitized, allowing attackers to inject malicious SQL queries. This is a classic authentication bypass vulnerability that can be exploited remotely without requiring any prior authentication or user interaction.
Critical Impact
Remote attackers can manipulate the Username parameter in the login form to inject arbitrary SQL commands, potentially bypassing authentication, extracting sensitive data from the database, or modifying database contents.

Technical Details for CVE-2025-13201
Vulnerability Analysis
This SQL Injection vulnerability (CWE-89) occurs due to improper neutralization of special elements used in SQL commands. The affected /login.php file accepts user-supplied input through the Username parameter and directly incorporates it into SQL queries without adequate sanitization or parameterization. This injection flaw falls under the broader category of Improper Neutralization of Special Elements in Output (CWE-74).
The vulnerability allows network-based attacks with low complexity, requiring no privileges or user interaction. An attacker can achieve partial compromise of confidentiality, integrity, and availability of the affected system. The exploit has been publicly disclosed and documented, increasing the risk of active exploitation.
Root Cause
The root cause of this vulnerability is insufficient input validation and the failure to use parameterized queries or prepared statements when processing user-supplied input in the authentication mechanism. The Username parameter is directly concatenated into SQL queries, allowing special characters to break out of the intended query structure and inject additional SQL commands.
Attack Vector
The attack can be performed remotely over the network against the /login.php endpoint. An attacker would craft a malicious payload in the Username field that includes SQL metacharacters and commands designed to manipulate the backend query logic. Common attack patterns include authentication bypass using payloads like ' OR '1'='1 or data exfiltration using UNION-based injection techniques.
Technical details and proof-of-concept information are available in the GitHub SQL Vulnerability Repository documentation. The attack targets the login form where the Username parameter is processed insecurely, allowing SQL statement manipulation through the authentication interface.
Detection Methods for CVE-2025-13201
Indicators of Compromise
- Unusual SQL error messages appearing in web server logs from /login.php requests
- Authentication attempts containing SQL metacharacters such as single quotes, double dashes, or UNION statements in the Username field
- Unexpected database query patterns or failed login attempts with anomalous payloads
- Web application firewall alerts for SQL injection patterns targeting the login endpoint
Detection Strategies
- Deploy web application firewall (WAF) rules to detect and block SQL injection patterns in POST parameters to /login.php
- Implement application-layer logging to capture and analyze all authentication attempts, flagging those containing SQL syntax
- Use intrusion detection systems (IDS) with signatures for common SQL injection attack patterns
- Monitor database query logs for anomalous queries originating from the web application
Monitoring Recommendations
- Enable detailed access logging for the /login.php endpoint and monitor for injection patterns
- Set up alerting for repeated failed authentication attempts with suspicious payload characteristics
- Review database audit logs for unauthorized data access or modification attempts
- Implement real-time monitoring of web server error logs for SQL-related exceptions
How to Mitigate CVE-2025-13201
Immediate Actions Required
- Remove or disable the Simple Cafe Ordering System from production environments until the vulnerability is addressed
- Implement input validation and sanitization for all user-supplied parameters, especially the Username field
- Deploy web application firewall rules to block SQL injection attempts against the login endpoint
- Review database access logs for signs of exploitation and rotate any potentially compromised credentials
Patch Information
No official vendor patch is currently available for this vulnerability. Users are advised to implement manual remediation by modifying the /login.php file to use parameterized queries or prepared statements. Consult Code Projects Security Resources for any updates or security advisories from the developer. Additional technical details are available through VulDB #332499.
Workarounds
- Implement prepared statements or parameterized queries in the /login.php authentication logic to prevent SQL injection
- Add server-side input validation to reject Username values containing SQL metacharacters
- Deploy a web application firewall with SQL injection detection rules in front of the application
- Restrict network access to the application to trusted IP ranges only until a proper fix is implemented
# Example Apache .htaccess rule to block common SQL injection patterns
# Add to the web application's .htaccess file
RewriteEngine On
RewriteCond %{QUERY_STRING} [^a-z](union|select|insert|update|delete|drop|alter|create|exec)[^a-z] [NC,OR]
RewriteCond %{REQUEST_BODY} [^a-z](union|select|insert|update|delete|drop|alter|create|exec)[^a-z] [NC]
RewriteRule .* - [F,L]
# Note: This provides basic protection but should not replace proper code fixes
# Implement parameterized queries as the primary remediation
