• Identify security vulnerabilities in the Java web application.
• Assess the potential impact of identified vulnerabilities.
• Provide actionable recommendations for remediation.
• Strengthen the overall security posture of the client’s web application.

Methodology

The penetration testing process followed a structured approach, including the following phases:

1. Reconnaissance: Gathering information about the application and its environment.
2. Scanning: Utilizing automated tools to detect potential vulnerabilities.
3. Exploitation: Attempting to exploit identified vulnerabilities to assess their impact.
4. Reporting: Documenting findings and providing recommendations for remediation.

Findings

During the penetration testing, several critical vulnerabilities were discovered:

1. Cross-Site Scripting (XSS)

• Description: The application was vulnerable to cross-site scripting attacks, allowing attackers to inject malicious scripts.
• Impact: Potential execution of malicious scripts in users’ browsers, leading to data theft and session hijacking.
• Recommendation: Implement input validation and output encoding. Use security libraries to sanitize user inputs.

1. Security Misconfiguration

• Description: The application had insecure configurations that could be exploited by attackers.
• Impact: Increased risk of unauthorized access and data breaches.
• Recommendation: Implement secure configuration guidelines. Regularly audit and review application configurations.

1. Insufficient Logging & Monitoring

• Description: The application lacked adequate logging and monitoring capabilities to detect and respond to security incidents.
• Impact: Delayed detection and response to security breaches.
• Recommendation: Implement comprehensive logging and monitoring. Ensure logs are securely stored and regularly reviewed.

1. Host Header Injection

• Description: The application was vulnerable to host header injection attacks, allowing attackers to manipulate host headers.
• Impact: Potential redirection of users to malicious websites and unauthorized access.
• Recommendation: Validate and sanitize host headers. Implement strict hostname validation on the server side.

1. Password Field with Autocomplete Enabled

• Description: Password input field with the autocomplete feature enabled.
• Impact: Increased risk of password theft through browser-based attacks.
• Recommendation: Disable autocomplete for password fields by setting the autocomplete attribute to off in HTML forms.
