CVE-2022-29499 is a command-injection vulnerability in the Service Appliance component of Mitel MiVoice Connect. Insufficient validation in a diagnostic script allows an unauthenticated remote attacker to submit specially crafted requests and execute commands on the appliance. Affected models include SA 100, SA 400, and Virtual SA, with vulnerable releases including R19.2 SP3 and earlier and R14.x deployments. The vulnerability has been exploited for initial access in ransomware intrusions.

A vulnerability in Mitel MiVoice Connect exploited by the Lorenz ransomware group to gain initial access to victim networks. The article notes at least 20,000 internet-connected platforms worldwide and urges users to install the vendor's patched software released in April 2022.
A remote code execution vulnerability in Mitel MiVoice VoIP appliances that Lorenz ransomware operators exploited for initial access to exposed devices.
A critical remote code execution vulnerability affecting the Mitel Service Appliance component of MiVoice Connect. Ransomware threat actors exploited it as a zero-day to gain initial access through a Linux-based VoIP appliance. Investigators recovered evidence of the exploit despite attackers deleting files and using anti-forensic techniques. Mitel patched the vulnerability in April and provided customers with a remediation script.
A vulnerability in Mitel telephony infrastructure that attackers exploited through two PHP pages on a perimeter CentOS system to retrieve and install a command-executing web shell. Although the victim subsequently patched the vulnerability, the existing backdoor survived and was later used to facilitate lateral movement, data exfiltration, and Lorenz ransomware deployment. The case demonstrates that patching does not remove persistence established before remediation.
