CVE-2026-26702: Personnel Property Equipment System SQLi

CVE-2026-26702 Overview

A critical SQL Injection vulnerability has been identified in sourcecodester Personnel Property Equipment System v1.0. The vulnerability exists in the /ppes/admin/myitem_reuse.php endpoint, allowing attackers to inject malicious SQL queries and potentially compromise the underlying database. This flaw enables unauthorized access to sensitive data, data manipulation, and potential complete system compromise.

Critical Impact

Unauthenticated attackers can exploit this SQL Injection vulnerability to extract sensitive data, modify database contents, or potentially achieve remote code execution on the underlying server.

Technical Details for CVE-2026-26702

Vulnerability Analysis

This SQL Injection vulnerability (CWE-89: Improper Neutralization of Special Elements used in an SQL Command) affects the administrative interface of the Personnel Property Equipment System. The vulnerable endpoint /ppes/admin/myitem_reuse.php fails to properly sanitize user-supplied input before incorporating it into SQL queries. This allows an attacker to manipulate database queries by injecting malicious SQL code through request parameters.

The vulnerability is exploitable over the network without requiring authentication or user interaction, making it particularly dangerous for publicly accessible deployments. Successful exploitation could lead to complete database compromise, including the ability to read, modify, or delete any data stored within the system.

Root Cause

The root cause of this vulnerability is insufficient input validation and the absence of parameterized queries (prepared statements) in the myitem_reuse.php script. User-supplied input is directly concatenated into SQL query strings without proper sanitization or escaping, creating a classic SQL Injection condition.

Attack Vector

The attack vector for this vulnerability is network-based, targeting the web application's administrative endpoint. An attacker can craft malicious HTTP requests containing SQL injection payloads directed at the /ppes/admin/myitem_reuse.php endpoint. The vulnerable parameter accepts user input that is directly interpolated into database queries, allowing attackers to:

• Extract sensitive information from the database using UNION-based or error-based injection techniques
• Bypass authentication mechanisms
• Modify or delete database records
• Potentially execute operating system commands if database permissions allow

For detailed technical information about the vulnerability, see the GitHub SQL Injection Report.

Detection Methods for CVE-2026-26702

Indicators of Compromise

• Unusual or malformed HTTP requests to /ppes/admin/myitem_reuse.php containing SQL keywords such as UNION, SELECT, INSERT, UPDATE, DELETE, or DROP
• Database error messages appearing in application logs or responses indicating malformed queries
• Unexpected database queries in database audit logs, particularly those containing comment sequences (--, /**/) or string concatenation operators
• Anomalous data access patterns or bulk data retrieval from the application database

Detection Strategies

• Deploy Web Application Firewall (WAF) rules to detect and block common SQL Injection patterns targeting the vulnerable endpoint
• Enable detailed logging for the web application and database server to capture suspicious query patterns
• Implement intrusion detection system (IDS) signatures for SQL Injection attack payloads
• Monitor for authentication bypass attempts and unauthorized administrative access

Monitoring Recommendations

• Configure real-time alerting for database errors originating from the Personnel Property Equipment System
• Establish baseline traffic patterns to the /ppes/admin/ directory and alert on anomalies
• Review access logs regularly for patterns indicative of automated SQL Injection scanning tools
• Monitor database query logs for unusual statement patterns or excessive query volumes

How to Mitigate CVE-2026-26702

Immediate Actions Required

• Remove or restrict access to the Personnel Property Equipment System from public networks until patched
• Implement network-level access controls to limit access to the administrative interface to trusted IP addresses only
• Deploy a Web Application Firewall (WAF) with SQL Injection protection rules in front of the application
• Review database permissions and restrict the application's database user to minimum required privileges

Patch Information

No official patch has been released by the vendor at this time. Organizations using this software should monitor the vendor's release channels and the GitHub repository for updates regarding security fixes. Consider replacing this software with a maintained alternative if patches are not forthcoming.

Workarounds

• Implement input validation at the application or web server level to reject requests containing SQL special characters
• Use a reverse proxy or WAF to filter malicious SQL Injection payloads before they reach the application
• Restrict network access to the application using firewall rules, limiting access to only trusted administrators
• If source code access is available, implement parameterized queries (prepared statements) to properly sanitize all user inputs before database operations

# Example: Restrict access to admin directory via .htaccess
# Add to /ppes/admin/.htaccess
<Files "myitem_reuse.php">
    Order Deny,Allow
    Deny from all
    Allow from 192.168.1.0/24
</Files>
