Web Application Security Assessment

Cosecai conducted a penetration test of the client's web application to evaluate its security across authentication, access control, session management, and data protection. Testing was carried out using OWASP standards to identify exploitable vulnerabilities before they could be leveraged by an attacker.

Testing combined manual verification with automated tools, including Burp Suite, Acunetix, and Gobuster, to ensure thorough coverage and accurate validation of findings. Assessment areas included access control, session handling, API security, input validation, authentication mechanisms, and security configuration review, all aligned with the OWASP Top 10 framework.

The assessment uncovered ten vulnerabilities: two high-risk, one medium-risk, and seven low-risk. Critical issues included privilege escalation and exposed AWS credentials, posing substantial risk to the confidentiality and integrity of the application. A CORS misconfiguration represented a medium-severity finding, while low-risk issues involved missing security headers and weak cookie configurations.

Priority was given to addressing access control weaknesses and rotating the exposed credentials. Recommendations also encompassed stricter CORS policies, enforced HTTPS, stronger session management, appropriate security headers, and adherence to least-privilege principles across the application.

Re-testing was performed to verify closure of identified vulnerabilities and confirm that no new issues had emerged during remediation. The engagement resulted in the elimination of critical risks and improved alignment with OWASP security standards.

Access control and credential security require immediate and ongoing focus, as multiple minor vulnerabilities can combine to create greater impact. Sustained security posture depends on continuous vulnerability management, regular assessments, and the adoption of DevSecOps practices.
