CVE-2026-26886: Men's Salon Management System SQLi Flaw

CVE-2026-26886 Overview

CVE-2026-26886 is a SQL Injection vulnerability affecting Sourcecodester Online Men's Salon Management System v1.0. The vulnerability exists in the /admin/services/manage_service.php endpoint, which fails to properly sanitize user input before incorporating it into SQL queries. This allows an authenticated attacker with administrative privileges to execute arbitrary SQL commands against the underlying database.

Critical Impact

Authenticated administrators can exploit this SQL Injection flaw to extract sensitive data from the database, including customer information, payment details, and system credentials.

Affected Products

• Oretnom23 Simple Online Men's Salon Management System v1.0
• Systems using /admin/services/manage_service.php endpoint

Technical Details for CVE-2026-26886

Vulnerability Analysis

This SQL Injection vulnerability (CWE-89) occurs in the administrative service management functionality of the Online Men's Salon Management System. The vulnerable endpoint at /admin/services/manage_service.php does not implement adequate input validation or parameterized queries when processing user-supplied data. While exploitation requires administrator-level authentication, a compromised admin account or malicious insider could leverage this flaw to extract confidential database contents.

The vulnerability allows for data exfiltration from the database, potentially exposing customer records, appointment details, and system configuration data. The attack requires network access and high-level privileges, which limits the overall exposure but does not eliminate the risk in environments where admin credentials may be compromised.

Root Cause

The root cause of this vulnerability is the direct concatenation of user-supplied input into SQL query strings without proper sanitization or the use of prepared statements. The manage_service.php script accepts parameters that are incorporated into database queries without being escaped or validated, creating a classic SQL Injection attack surface.

Attack Vector

The attack is executed over the network against the /admin/services/manage_service.php endpoint. An attacker must first authenticate with administrative credentials to access the vulnerable functionality. Once authenticated, the attacker can inject malicious SQL syntax through vulnerable parameters to manipulate database queries and extract sensitive information.

The injection point allows read access to database contents. Since the vulnerability requires high privileges, exploitation scenarios typically involve compromised admin accounts, social engineering attacks targeting administrators, or malicious insiders with legitimate admin access.

Technical details and proof-of-concept information are available in the GitHub PoC Repository.

Detection Methods for CVE-2026-26886

Indicators of Compromise

• Unusual SQL error messages in application logs originating from /admin/services/manage_service.php
• Abnormal database query patterns or increased query execution times from admin sessions
• Log entries showing SQL meta-characters (single quotes, double dashes, UNION keywords) in request parameters
• Unexpected data access patterns from administrator accounts

Detection Strategies

• Implement Web Application Firewall (WAF) rules to detect SQL Injection patterns targeting the /admin/services/manage_service.php endpoint
• Enable database query logging and monitor for anomalous SELECT statements containing UNION or subquery patterns
• Configure intrusion detection systems (IDS) to alert on SQL Injection signatures in HTTP POST/GET requests to admin endpoints
• Deploy application-layer monitoring to detect parameter manipulation attempts

Monitoring Recommendations

• Enable verbose logging for the /admin/services/ directory and review logs regularly for suspicious activity
• Implement real-time alerting for database errors that may indicate SQL Injection attempts
• Monitor admin user sessions for unusual behavior patterns or access from unexpected IP addresses
• Set up automated scanning for SQL Injection vulnerabilities in the application codebase

How to Mitigate CVE-2026-26886

Immediate Actions Required

• Restrict access to the /admin/services/manage_service.php endpoint to trusted IP addresses only
• Implement additional authentication layers (MFA) for administrative access
• Review and audit all administrator accounts for potential compromise
• Consider taking the application offline if it processes sensitive customer data until patching is complete

Patch Information

No official vendor patch has been released at this time. The software is developed by oretnom23 and distributed through Sourcecodester. Organizations using this application should monitor the GitHub PoC Repository for updates and consider implementing manual code fixes.

Workarounds

• Implement input validation on all user-supplied parameters in manage_service.php before database operations
• Refactor database queries to use prepared statements with parameterized queries (PDO or MySQLi prepared statements)
• Deploy a Web Application Firewall (WAF) with SQL Injection protection rules in front of the application
• Restrict database user privileges to minimum required access (principle of least privilege)
• Consider replacing the vulnerable component with a more secure alternative if the vendor does not provide timely patches
