Ivanti Firmware Security Issues: Understanding the Risks and Solutions

: ivanti firmware security issues: understanding the risks and solutions

Overview

Eclypsium's research revealed that Ivanti's Pulse Secure firmware has numerous unreported issues, including multiple outdated and unsupported software components. This discovery follows the exploitation of several zero-day vulnerabilities in Ivanti software in recent weeks. Notably, Ivanti addressed two critical zero-day vulnerabilities in its Ivanti Policy Secure (IPS) and Ivanti Connect Secure (ICS) software, tracked as CVE-2023-46805 and CVE-2024-21887, capable of remote code execution. Additionally, two new bugs were disclosed in IPS and ICS, with one being a privilege escalation flaw (CVE-2024-21888) and the other a server-side request forgery (CVE-2024-21893), the latter being targeted in attacks.

Eclypsium's research, based on reverse-engineering firmware for ICS in Ivanti's Pulse Secure product, exposed various weaknesses in the firmware, such as the use of an outdated version of Linux for the devices' operating system, several years past its end-of-life. Furthermore, the analysis revealed multiple outdated packages, including an end-of-life Linux kernel, outdated OpenSSL, Python, Perl, and Bash components.

The research also highlighted Ivanti's Integrity Checker Tool, which exhibited significant security flaws, potentially allowing attackers to leave persistent C2 implants undetected. This is particularly concerning as network devices like Ivanti's are increasingly targeted by threat actors due to their exposure to the internet and lack of support for endpoint detection and response products.

The findings from Eclypsium's research underscore the importance of visibility into digital supply chains and the demand for Software Bill of Materials (SBOMs) from vendors. This research comes at a time when the U.S. government is focusing on holding software vendors accountable for insecure products with significant weaknesses and vulnerabilities. While the Biden administration has proposed shifting liability for such insecure products to developers and vendors, the real solution may lie in transparency throughout the supply chain, as highlighted by Eclypsium's director of threat research and intelligence, Nate Warfield.

The implications of these vulnerabilities and weaknesses are significant, as they can potentially lead to exploitation by threat actors, compromising the security and integrity of organizations' network devices. It is crucial for Ivanti and other vendors to address these vulnerabilities promptly and improve transparency in their supply chains to mitigate the risks associated with such security flaws.

Conclusion & Personal Recommendation

In conclusion, the Ivanti firmware has been found to have multiple security issues, including outdated and unsupported software components. These vulnerabilities pose significant risks to organizations relying on Ivanti Connect Secure and Policy Secure endpoints for secure access.

To mitigate these risks, it is recommended that organizations keep all operating systems, software, and firmware up to date. Timely patching is one of the most efficient and cost-effective steps an organization can take to minimize its exposure to cybersecurity threats. Organizations should patch vulnerable software and hardware systems within 24 to 48 hours of vulnerability disclosure.

Additionally, it is recommended that organizations perform regular security assessments and penetration testing to identify vulnerabilities and address them before they can be exploited. Organizations should also consider implementing multi-factor authentication and access controls to limit the impact of potential breaches.

By following these best practices, organizations can significantly reduce their risk of falling victim to cyber attacks targeting Ivanti firmware vulnerabilities.
