🌐 Web Application Security Audit Report #

Subject: Security Audit of Web Application
Date of Test: 1 May 2024 – 10 May 2024
Location: Bristol, United Kingdom
Company Conducting the Test: CyberSentinel Solutions LTD
Version: 1.0

📑 Executive Summary #

This document presents a comprehensive security assessment of a single-page web application conducted by CyberSentinel Solutions LTD in May 2024. The assessment aimed to identify vulnerabilities that could compromise the application’s confidentiality, integrity, and availability. The report also outlines detailed remediation strategies for each identified issue.

The application was tested in various user roles, including unauthenticated users, standard authenticated users, and administrative users. Special emphasis was placed on areas vulnerable to common web threats, such as Cross-Site Scripting (XSS), SQL injection, Cross-Site Request Forgery (CSRF), and more advanced attacks like server misconfiguration and cryptographic flaws.

Roles Tested:

• [01] Unauthenticated User (visitor)
• [02] Authenticated User (registered user)
• [03] Administrator (admin)

🎯 Test Objective #

The primary goal of this security audit was to comprehensively analyze the web application for vulnerabilities that could:

1. Compromise sensitive user data.
2. Allow unauthorized access to administrative features.
3. Result in service outages or performance degradation.

In addition, the audit focused on adherence to modern security best practices as outlined by:

• OWASP (Open Web Application Security Project) Top 10
• OWASP Application Security Verification Standard (ASVS)
• ISO/IEC 27001 standards for information security

🔬 Phases of the Security Assessment #

Phase 1: Reconnaissance and Information Gathering #

• Date: 1 May 2024 – 2 May 2024
• Objective: Understand the architecture and gather data to inform later stages of testing.
• Procedure: DNS Analysis using Nmap and Dig to identify subdomains. Service Detection using Nmap to find open ports (80/443). Web Server Fingerprinting using Nikto.
• Outcome: The server was running Nginx 1.20.2 (no publicly disclosed critical vulnerabilities, but update advised). Misconfigured HTTP headers detected (e.g., missing Content-Security-Policy and HSTS).

Phase 2: Vulnerability Assessment #

• Date: 3 May 2024 – 7 May 2024
• Objective: Identify potential security vulnerabilities using manual and automated methods.
• 1. Cross-Site Scripting (XSS): Outcome: Stored XSS identified in the comment section of user profiles. Allows injection of malicious JavaScript executed when an admin views a user’s profile.
• 2. SQL Injection: Outcome: No exploitable SQL injection vulnerabilities detected.
• 3. Cross-Site Request Forgery (CSRF): Outcome: The application lacks proper CSRF tokens for critical operations, allowing attackers to execute unauthorized requests.
• 4. Broken Authentication and Session Management: Outcome: Sessions lacked HttpOnly and SameSite attributes, increasing the risk of session hijacking.

Phase 3: Exploitation #

• Date: 8 May 2024 – 9 May 2024
• Objective: Confirm the severity of vulnerabilities by attempting exploitation.
• Stored XSS: Exploited to perform session theft of an administrator account by injecting a payload that stole cookies using JavaScript.
• CSRF: Crafted a CSRF attack that successfully modified a user’s email address without their consent.

Phase 4: Post-Exploitation Analysis #

• Date: 10 May 2024
• Objective: Review the possible outcomes of successful exploitation to assess damage.
• Outcome: XSS could lead to full account takeover via session hijacking. CSRF could be used to modify sensitive user data (e.g., password resets or email changes).

📊 Vulnerability Overview Matrix #

🛡️ Strategic Recommendations #

1. Fix XSS Issues: Implement strict input sanitization and context-aware output encoding across all input fields.
2. Implement CSRF Tokens: Introduce cryptographically secure anti-CSRF tokens for all forms and state-changing actions.
3. Enhance Session Security: Add HttpOnly, Secure, and SameSite=Strict attributes to session cookies to prevent hijacking and misuse.
4. Update Third-Party Libraries: Ensure all external libraries, especially JavaScript frameworks, are kept up-to-date to prevent exploitation of known vulnerabilities.
5. Add Security Headers:
   • Content-Security-Policy (CSP): Restrict the execution of scripts and other resources to trusted sources to provide defense-in-depth against XSS.
   • HTTP Strict-Transport-Security (HSTS): Ensure all communication is securely handled over HTTPS.
6. Ongoing Security Audits: Regular testing should be conducted to ensure that the application remains secure against evolving threats.
