Vulnerability in Jenkins Server Exposes Blockchain Infrastructure

During a recent Penetration Testing of a blockchain system for one of our clients, we identified 15 vulnerabilities and 2 of them are Critical Risk level. One of the critical risks were in the Jenkins server, CVE-2024-23897. This vulnerability, present in Jenkins versions 2.441 and earlier, allows unauthenticated attackers to read the first three lines of arbitrary files on the server.

The Jenkins server's accessibility from the public internet increased the risk of unauthorized access and potential exploitation, potentially leading to the discovery of more critical vulnerabilities. While immediate patching is essential, the impact of this flaw cannot be underestimated. Unauthenticated access to sensitive information within the server could facilitate further exploitation and privilege escalation.

This discovery highlights the urgency of proactive security measures in safeguarding blockchain infrastructures. By promptly addressing and remedying any vulnerabilities, organizations can safeguard their systems against exploitation and uphold the integrity and confidentiality of the operations.

Objectives of
Penetration Testing


Identifying Vulnerabilities	Evaluating Security Posture
To discover existing weaknesses in systems, networks, or applications. This includes testing for vulnerabilities like unpatched software, insecure configurations, weak encryption, and other security loopholes.	To assess the overall security strength of the IT infrastructure. This helps in understanding how resistant the system is to potential attacks under different scenarios


Validating Existing Security Measures	Risk Assessment
To test the effectiveness of current security measures, including firewalls, intrusion detection systems, and anti-virus solutions, and ensuring they are configured correctly and working as intended.	To evaluate the risks associated with identified vulnerabilities. This involves understanding the potential impact and likelihood of exploitation, helping prioritize the remediation efforts.


Compliance with Regulations	Testing Incident Response
To ensure compliance with national, international, or industry-specific regulations and standards like GDPR, HIPAA, PCI-DSS, etc., which often require regular security assessments.	To check how effectively the organization can detect and respond to security incidents. This includes evaluating the efficiency of incident response plans and the readiness of the incident response team.
