CVE-2026-36944: Repair Shop Management System SQLi Flaw

CVE-2026-36944 Overview

Sourcecodester Computer and Mobile Repair Shop Management System v1.0 contains an SQL injection vulnerability in the file /rsms/admin/repairs/view_details.php. This web application vulnerability allows authenticated attackers with high privileges to inject malicious SQL queries through the network, potentially enabling unauthorized data access from the underlying database.

Critical Impact

Authenticated attackers can exploit this SQL injection flaw to extract sensitive information from the database, including customer data, repair records, and potentially administrative credentials stored within the application.

Affected Products

• Sourcecodester Computer and Mobile Repair Shop Management System v1.0
• PHP applications utilizing the vulnerable view_details.php endpoint
• Installations with network-accessible admin panels

Technical Details for CVE-2026-36944

Vulnerability Analysis

This SQL injection vulnerability exists in the administrative repair management functionality of the application. The vulnerable endpoint at /rsms/admin/repairs/view_details.php fails to properly sanitize user-supplied input before incorporating it into SQL queries. While the vulnerability requires high-privilege authentication to exploit, it still poses a risk in multi-admin environments or scenarios where an attacker has compromised administrative credentials.

The vulnerability allows for confidentiality impact through unauthorized data extraction. The attack can be executed remotely over the network without requiring user interaction, making it exploitable in automated attack scenarios once valid credentials are obtained.

Root Cause

The root cause is classified under CWE-89 (Improper Neutralization of Special Elements used in an SQL Command). The view_details.php script constructs SQL queries using unsanitized input parameters, allowing attackers to manipulate the query structure. This typically occurs when user input is directly concatenated into SQL statements rather than using parameterized queries or prepared statements.

Attack Vector

The attack is network-based and targets the administrative interface of the repair shop management system. An authenticated administrator can craft malicious requests to the view_details.php endpoint containing SQL injection payloads. These payloads can modify the intended SQL query logic to extract data from other database tables or bypass access controls within the database layer.

The exploitation flow typically involves:

1. Authenticating to the admin panel with valid high-privilege credentials
2. Navigating to the repairs view details functionality
3. Injecting SQL syntax through vulnerable parameters
4. Extracting sensitive database contents through error-based, union-based, or blind SQL injection techniques

Detection Methods for CVE-2026-36944

Indicators of Compromise

• Unusual SQL error messages in application logs originating from view_details.php
• HTTP requests to /rsms/admin/repairs/view_details.php containing SQL keywords like UNION, SELECT, OR 1=1, or encoded variants
• Database query logs showing malformed or unexpected queries from the repairs module
• Anomalous data extraction patterns or bulk data access from administrative sessions

Detection Strategies

• Deploy Web Application Firewall (WAF) rules to detect SQL injection patterns in requests to the admin panel
• Implement database activity monitoring to flag queries with unusual syntax or unauthorized table access
• Enable detailed PHP error logging and monitor for SQL-related exceptions from the vulnerable endpoint
• Configure SIEM correlation rules to identify multiple failed SQL injection attempts followed by successful data exfiltration

Monitoring Recommendations

• Monitor access logs for the /rsms/admin/repairs/view_details.php endpoint for suspicious parameter values
• Implement real-time alerting on database queries containing injection signatures from the application service account
• Review administrative user activity logs for unusual access patterns to the repairs module
• Enable application-level audit logging for all database interactions in the repair management module

How to Mitigate CVE-2026-36944

Immediate Actions Required

• Restrict network access to the administrative interface using IP allowlisting or VPN requirements
• Implement additional authentication factors for administrative access to reduce credential compromise risk
• Deploy a Web Application Firewall with SQL injection protection rules in front of the application
• Review and audit administrative user accounts, removing any unnecessary high-privilege access
• Consider taking the vulnerable endpoint offline if not critical to operations until a patch is available

Patch Information

No official vendor patch has been released for this vulnerability at the time of publication. Organizations should monitor the Sourcecodester project for security updates and apply patches immediately when available. As this is an open-source project, consider reviewing and implementing community-contributed fixes if they become available through the project's repository.

Workarounds

• Implement input validation at the web server level using mod_security or similar modules to filter SQL injection payloads
• Modify the view_details.php file to use prepared statements with parameterized queries instead of direct string concatenation
• Restrict database user permissions for the application to minimum required privileges (read-only where possible)
• Place the administrative interface behind a reverse proxy with request filtering capabilities
• Implement rate limiting on the admin endpoints to slow down automated exploitation attempts
