CVE-2024-36446
📋 TL;DR
This vulnerability allows authenticated attackers to bypass authorization controls in Mitel MiVoice MX-ONE's provisioning manager. Attackers could gain unauthorized access to system functions they shouldn't have. Organizations using affected versions of MiVoice MX-ONE are at risk.
💻 Affected Systems
- Mitel MiVoice MX-ONE
📦 What is this software?
⚠️ Risk & Real-World Impact
Worst Case
An attacker gains administrative control over the telephony system, potentially intercepting calls, modifying configurations, or disrupting service.
Likely Case
An authenticated user escalates privileges to access sensitive provisioning functions or system data they shouldn't have access to.
If Mitigated
With proper network segmentation and access controls, impact is limited to the telephony system itself rather than broader network compromise.
🎯 Exploit Status
Exploitation requires authenticated access but bypasses authorization checks. No public exploit code available at this time.
