A critical security vulnerability has been discovered in Mitel MiCollab, a widely used enterprise collaboration platform, leaving organizations vulnerable to data breaches. The flaw, classified as a zero-day exploit, allows attackers to gain unauthorized access to sensitive files stored on the server’s filesystem.
Mitel MiCollab is a comprehensive interaction solution utilized by businesses of all sizes, from large corporations to small and medium-sized enterprises. Its features include voice and video calling, instant messaging, presence details, audio conferencing, and team collaboration tools, making it a central hub for many organizations’ communication needs.
The zero-day vulnerability was uncovered by researchers at watchTowr, who responsibly disclosed the issue to Mitel in August.Despite the severity of the flaw, Mitel has yet to release a patch, leaving users exposed for over 90 days. “watchTowr contacted Mitel on August 26 about the new vulnerability. Mitel informed watchTowr of plans to patch the first week of December 2024. At the time of publishing, there has been no update on the Mitel Security Advisory page,” stated a watchTowr report.

The zero-day exploit was discovered during an examination into previously reported vulnerabilities in MiCollab. Researchers were examining CVE-2024-35286, an SQL injection flaw patched in May, and CVE-2024-41713, an authentication bypass issue addressed in October.While probing the ‘ReconcileWizard’ servlet, they discovered that injecting a path traversal string into the ‘reportName’ parameter of an XML-based API request allowed them to access sensitive files like ‘/etc/passwd,’ wich contains crucial system account information.
Although technically less critical than the other two vulnerabilities, this zero-day flaw poses a significant risk as it enables unauthorized access to sensitive system files. This discovery comes at a time when MiCollab has already been targeted by threat actors in recent DDoS attacks, highlighting the urgency of addressing this vulnerability.
Protecting Your Institution
given the lack of a patch, organizations using Mitel MiCollab are strongly advised to implement immediate mitigation measures.these include:
- Restrict access to the MiCollab server to trusted IP ranges or internal networks only.
- Implement firewall rules to block unauthorized external access to the application.
- Actively monitor logs for suspicious activity targeting the ReconcileWizard servlet or any path traversal patterns.
- Be vigilant for any unexpected access attempts to sensitive files or configuration data.
- if feasible, disable or restrict access to the ReconcileWizard servlet.
While awaiting a patch from Mitel,users should ensure they are running the latest version of MiCollab,which addresses other critical vulnerabilities recently discovered.
