CVE-2025-69562: Mobile Shop Management System SQLi Flaw

CVE-2025-69562 Overview

A critical SQL Injection vulnerability has been identified in code-projects Mobile Shop Management System version 1.0. The vulnerability exists in the /insertmessage.php endpoint and can be exploited through the userid parameter. This flaw allows remote attackers to execute arbitrary SQL commands against the backend database without requiring authentication, potentially leading to complete database compromise, data exfiltration, and unauthorized system access.

Critical Impact

This SQL Injection vulnerability enables unauthenticated attackers to execute arbitrary SQL queries, potentially exposing all database contents, modifying or deleting data, and in some configurations, achieving remote code execution on the underlying server.

Affected Products

• code-projects Mobile Shop Management System 1.0
• /insertmessage.php endpoint

Technical Details for CVE-2025-69562

Vulnerability Analysis

This vulnerability is classified as CWE-89 (SQL Injection), which occurs when user-supplied input is incorporated into SQL queries without proper sanitization or parameterization. In the case of Mobile Shop Management System 1.0, the /insertmessage.php script directly incorporates the userid parameter into database queries, allowing attackers to manipulate query logic.

The attack surface is accessible over the network without requiring any user interaction or prior authentication. Successful exploitation grants attackers high-level access to confidentiality, integrity, and availability of the database system. Attackers can extract sensitive customer data, manipulate records, or cause service disruption through destructive queries.

Root Cause

The root cause of this vulnerability is improper input validation and the use of unsanitized user input directly in SQL query construction. The userid parameter in /insertmessage.php is not properly escaped, filtered, or handled through prepared statements before being used in database operations. This is a classic example of dynamic SQL query construction that fails to implement defense-in-depth against injection attacks.

Attack Vector

The vulnerability is exploitable via network-based HTTP requests to the vulnerable endpoint. An attacker can craft malicious requests containing SQL metacharacters and commands within the userid parameter. The attack requires no authentication and no user interaction, making it highly exploitable in internet-facing deployments.

Common SQL Injection techniques applicable to this vulnerability include:

• Union-based injection to extract data from other database tables
• Boolean-based blind injection to infer database contents through true/false responses
• Time-based blind injection using database-specific delay functions
• Stacked queries to execute multiple SQL statements (database-dependent)

For detailed technical information about this vulnerability, refer to the GitHub Gist documentation and the Gitee issue discussion.

Detection Methods for CVE-2025-69562

Indicators of Compromise

• HTTP requests to /insertmessage.php containing SQL syntax characters such as single quotes ('), double quotes ("), semicolons (;), or comment sequences (--, /*)
• Unusual or malformed values in the userid parameter including SQL keywords like UNION, SELECT, INSERT, DROP, or OR 1=1
• Database error messages appearing in application responses that reveal SQL syntax or database structure
• Unexpected database queries or query patterns in database logs originating from the web application

Detection Strategies

• Deploy Web Application Firewall (WAF) rules to detect and block SQL Injection patterns targeting the /insertmessage.php endpoint
• Implement database activity monitoring to identify anomalous query patterns, especially queries containing injection signatures
• Configure application logging to capture all requests to /insertmessage.php with full parameter values for forensic analysis
• Use SentinelOne Singularity platform to monitor for post-exploitation behaviors such as unusual database process activity or data exfiltration attempts

Monitoring Recommendations

• Enable verbose logging on the web server to capture all HTTP request parameters for the vulnerable endpoint
• Monitor database server logs for query errors, unusual data access patterns, or bulk data retrieval operations
• Set up alerting for authentication failures or privilege escalation attempts that may follow initial SQL injection
• Implement network traffic analysis to detect large data transfers from the database server that could indicate exfiltration

How to Mitigate CVE-2025-69562

Immediate Actions Required

• Take the Mobile Shop Management System offline or restrict network access to the /insertmessage.php endpoint until a patch is applied
• Implement WAF rules to filter SQL injection patterns in the userid parameter as a temporary protective measure
• Review database logs for evidence of prior exploitation and assess potential data exposure
• If the application source is available, implement prepared statements or parameterized queries for the vulnerable endpoint

Patch Information

No official vendor patch information is currently available for this vulnerability. Organizations using code-projects Mobile Shop Management System 1.0 should monitor the project resources and Gitee issue tracker for updates. Consider reaching out to the project maintainers regarding remediation timeline.

Workarounds

• Block or restrict access to /insertmessage.php at the network or application level if the functionality is not critical
• Implement input validation at the web server level using ModSecurity or similar WAF with OWASP Core Rule Set
• If source code modification is possible, replace dynamic SQL queries with prepared statements using PDO or mysqli parameterized queries in PHP
• Deploy network segmentation to limit database server exposure and restrict connections to only necessary application servers
• Consider replacing the vulnerable application with a maintained alternative that follows secure coding practices

# Example: Block access to vulnerable endpoint using Apache .htaccess
<Files "insertmessage.php">
    Order Deny,Allow
    Deny from all
    # Allow only from trusted IPs if needed
    # Allow from 192.168.1.0/24
</Files>
