CVE-2026-36946: Repair Shop Management System SQLi Flaw

CVE-2026-36946 Overview

CVE-2026-36946 is a SQL Injection vulnerability affecting Sourcecodester Computer and Mobile Repair Shop Management System v1.0. The vulnerability exists in the file /rsms/admin/inquiries/view_details.php, allowing authenticated attackers with high privileges to execute arbitrary SQL queries against the underlying database through specially crafted input parameters.

Critical Impact

Authenticated attackers with administrative access can exploit this SQL injection flaw to extract sensitive information from the database, potentially exposing customer data, repair records, and other confidential business information stored in the management system.

Affected Products

• Oretnom23 Computer and Mobile Repair Shop Management System v1.0
• Systems running /rsms/admin/inquiries/view_details.php endpoint

Technical Details for CVE-2026-36946

Vulnerability Analysis

This SQL Injection vulnerability (CWE-89) occurs due to improper neutralization of special elements used in SQL commands within the view_details.php file of the admin inquiries module. The application fails to properly sanitize user-supplied input before incorporating it into SQL queries, creating an injection point that can be exploited by authenticated administrative users.

The attack requires network access and high-level privileges (administrative authentication), which limits the attack surface but still presents a significant risk in environments where administrative credentials may be compromised or where insider threats exist. Successful exploitation allows unauthorized read access to database contents, potentially exposing confidential customer information, repair tickets, and financial data stored within the system.

Root Cause

The root cause of this vulnerability is the direct concatenation or improper parameterization of user-controlled input into SQL queries within the view_details.php file. The application does not implement proper input validation, prepared statements, or parameterized queries to separate SQL code from user data, allowing malicious SQL syntax to be interpreted as part of the database query.

Attack Vector

The attack is executed over the network by an authenticated user with administrative privileges. The attacker submits crafted input through the view_details.php endpoint, manipulating the underlying SQL query to extract data beyond their authorized scope. The exploitation requires no user interaction and affects the confidentiality of stored data.

The vulnerability specifically targets the inquiries management functionality, where user-controlled parameters are passed to database queries without adequate sanitization. An attacker can leverage standard SQL injection techniques such as UNION-based injection, boolean-based blind injection, or time-based blind injection to enumerate and exfiltrate database contents.

Detection Methods for CVE-2026-36946

Indicators of Compromise

• Unusual or malformed requests to /rsms/admin/inquiries/view_details.php containing SQL syntax characters such as single quotes, double dashes, or UNION keywords
• Database query logs showing unexpected SELECT statements or error messages indicating SQL syntax errors
• Abnormal data access patterns from administrative accounts, particularly bulk data retrieval from customer or inquiry tables

Detection Strategies

• Deploy Web Application Firewall (WAF) rules to detect and block common SQL injection patterns targeting the affected endpoint
• Implement database activity monitoring to alert on unusual query patterns or unauthorized data access attempts
• Enable verbose logging on the application server to capture all requests to administrative endpoints for forensic analysis
• Configure intrusion detection systems (IDS) to monitor for SQL injection attack signatures in HTTP traffic

Monitoring Recommendations

• Monitor authentication logs for administrative account access and correlate with requests to vulnerable endpoints
• Set up alerts for database errors that may indicate SQL injection attempts, such as syntax errors or permission denials
• Review web server access logs regularly for suspicious query string patterns targeting /rsms/admin/inquiries/view_details.php

How to Mitigate CVE-2026-36946

Immediate Actions Required

• Restrict access to the administrative interface to trusted IP addresses only using firewall rules or .htaccess configurations
• Implement additional authentication controls such as multi-factor authentication for administrative accounts
• Audit all administrative user accounts and remove any unnecessary or inactive accounts
• Consider temporarily disabling the vulnerable view_details.php functionality until a patch is available

Patch Information

No official vendor patch information is currently available for this vulnerability. Administrators should monitor the Sourcecodester project page and community forums for security updates. Given that this is an open-source application from Sourcecodester, users may need to implement manual code fixes or apply community-contributed patches.

Organizations using this software should evaluate the risk and consider migrating to a more actively maintained solution if security updates are not provided in a timely manner.

Workarounds

• Implement input validation at the application level by modifying the view_details.php file to use prepared statements with parameterized queries
• Deploy a Web Application Firewall (WAF) in front of the application to filter malicious SQL injection payloads
• Restrict database user permissions to limit the impact of successful SQL injection attacks, ensuring the application database user has only minimum required privileges
• Isolate the application server and database on separate network segments with strict access controls

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

# Alternatively, for nginx - add to server block:
# location /rsms/admin/ {
#     allow 192.168.1.0/24;
#     allow 10.0.0.0/8;
#     deny all;
# }
