CVE-2025-6861: Critical SQL Injection Flaw Discovered in Best Salon Management System

Welcome back to the blog! Today, we're diving into a newly discovered vulnerability affecting SourceCodester's Best Salon Management System. This flaw, identified as CVE-2025-6861, poses a significant risk to salons using this software. Let's break down the details and what you can do to protect yourself.

Vulnerability Details

  • CVE ID: CVE-2025-6861
  • Description: A critical SQL injection vulnerability exists in SourceCodester Best Salon Management System 1.0, affecting the `/panel/add_plan.php` file. By manipulating the `plan_name`, `description`, `duration_days`, or `price` arguments, attackers can inject malicious SQL code into the database.
  • CVSS Score:
    • CVSS v3.1: 6.3 (Medium) CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:L/I:L/A:L
    • CVSS v4.0: 5.3 (Medium) CVSS:4.0/AV:N/AC:L/AT:N/PR:L/UI:N/VC:L/VI:L/VA:L/SC:N/SI:N/SA:N/E:P/CR:X/IR:X/AR:X/MAV:X/MAC:X/MAT:X/MPR:X/MUI:X/MVC:X/MVI:X/MVA:X/MSC:X/MSI:X/MSA:X/S:X/AU:X/R:X/V:X/RE:X/U:X

    Explanation: The CVSS score indicates a medium severity because a low-privileged attacker can remotely exploit the vulnerability without user interaction, leading to partial confidentiality, integrity, and availability impact. The 'P' (Proof-of-Concept) exploit maturity suggests that exploit code is publicly available, increasing the risk.

  • Exploit Requirements: An attacker needs to be authenticated with low privileges to exploit this vulnerability. However, no user interaction is required.
  • Affected Product: SourceCodester Best Salon Management System 1.0
  • CWE: CWE-89 (SQL Injection) - This means the application is constructing SQL queries with untrusted input, allowing attackers to manipulate the query and potentially access, modify, or delete data in the database.

Timeline of Events

  • 2025-06-29: Vulnerability publicly disclosed.
  • 2025-06-29: CVE ID assigned (CVE-2025-6861).
  • 2025-06-29: Proof-of-concept exploit released.

Exploitability & Real-World Risk

SQL injection vulnerabilities are particularly dangerous because they can allow attackers to bypass authentication, steal sensitive customer data (names, addresses, payment information), modify appointment schedules, or even gain complete control of the database server. Imagine an attacker changing appointment times to disrupt a salon's operations or stealing customer credit card details. Given that a proof-of-concept exploit is already available, the risk is significantly heightened.

Recommendations

  • Apply the Patch: Check with SourceCodester for a patch or updated version of the Best Salon Management System that addresses this vulnerability. This is the most critical step.
  • Input Validation: If patching isn't immediately possible, implement strict input validation on the `plan_name`, `description`, `duration_days`, and `price` parameters in the `/panel/add_plan.php` file. Sanitize and escape all user-supplied data before using it in SQL queries.
  • Principle of Least Privilege: Ensure that the database user account used by the application has the minimum necessary privileges. Avoid using a database administrator account.
  • Web Application Firewall (WAF): Deploy a WAF to detect and block SQL injection attempts.

Technical Insight

The vulnerability likely stems from a lack of proper sanitization or escaping of user-provided data before it's incorporated into SQL queries. For example, if the application directly inserts the value of the `plan_name` parameter into an SQL query without properly escaping special characters (like single quotes), an attacker can inject arbitrary SQL code.
