CVE-2023-31460
📋 TL;DR
This vulnerability allows authenticated attackers with internal network access to execute arbitrary commands on MiVoice Connect systems through command injection in URL parameters. It affects MiVoice Connect versions 9.6.2208.101 and earlier. Attackers could potentially gain full control of affected systems.
💻 Affected Systems
- MiVoice Connect
📦 What is this software?
⚠️ Risk & Real-World Impact
Worst Case
Full system compromise leading to data exfiltration, lateral movement within the network, and persistent backdoor installation.
Likely Case
Unauthorized command execution leading to service disruption, configuration changes, or credential harvesting.
If Mitigated
Limited impact due to network segmentation and strict access controls preventing authenticated attackers from reaching vulnerable components.
🎯 Exploit Status
Command injection vulnerabilities are typically straightforward to exploit once the attack vector is identified. Requires authenticated access.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Versions after 9.6.2208.101
Vendor Advisory: https://www.mitel.com/support/security-advisories/mitel-product-security-advisory-23-0007
Restart Required: Yes
