Mitel MiCollab Vulnerabilities Expose Sensitive Files via Exploit Chain
2024-12-06
Learn about the critical importance of timely patch management and the potential risks of unpatched collaboration tools in enterprise environments.
A proof-of-concept exploit demonstrates how a zero-day arbitrary file read vulnerability in Mitel MiCollab can be combined with a previously patched critical bug to access sensitive files on affected systems. Despite Mitel being informed over 100 days ago, a patch for the zero-day is still pending. MiCollab is a widely used enterprise collaboration tool, making it an appealing target for cybercriminals. The earlier critical flaw, which allowed path traversal and unauthorized data access, was fixed in October. However, the new flaw remains unpatched, allowing potential attackers to bypass authentication and access critical system files.

Mitel MiCollab, NuPoint Unified Messaging (NPM) component
A recent security incident has highlighted significant vulnerabilities in Mitel's MiCollab, an enterprise collaboration platform. These vulnerabilities include a zero-day arbitrary file read flaw and a critical SQL injection bug that was previously patched. Together, they pose a serious threat to organizations using this widely adopted tool. The zero-day vulnerability allows unauthorized access to sensitive files on the MiCollab platform. This flaw has not yet been patched, despite being disclosed to Mitel over 100 days ago. Attackers can exploit this vulnerability to read critical files, such as system configurations and user data, posing a risk to affected systems. Earlier this year, researchers discovered a critical SQL injection vulnerability in the NuPoint Unified Messaging component of MiCollab. This flaw, rated 9.8 in severity, enabled attackers to perform path traversal attacks, potentially leading to unauthorized data access or corruption. Mitel addressed and patched this issue in October. Researchers have developed a proof-of-concept (PoC) exploit that chains the zero-day file read vulnerability with the now-patched SQL injection flaw (CVE-2024-35286). By combining these vulnerabilities, attackers can bypass authentication and access sensitive files, such as the "/etc/passwd" file, which contains account information. Mitel MiCollab is used by more than 16,000 instances across the internet, making it an attractive target for cybercriminals, including ransomware groups. Organizations relying on this platform are advised to be vigilant and monitor for updates from Mitel regarding the patch for the zero-day vulnerability. This incident underscores the critical importance of timely patch management. Enterprises must ensure that all software components are up-to-date to protect against emerging threats and vulnerabilities.Overview of Mitel MiCollab Vulnerabilities
