CVE-2022-29499 Scanner

Mitel MiVoice Connect is a telephony solution designed for businesses to facilitate communication through an IP-based phone system. It is used widely in enterprises that require a stable and efficient voice communication system. The product offers features such as voice calling, voicemail, conferencing, and instant messaging. This Mitel solution integrates well with various communication networks and is often utilized in corporate environments. Continuously updated to ensure security, Mitel MiVoice Connect aims to provide reliable service across diverse organizational structures. The platform supports integration with both on-premises and cloud environments for flexible deployment.

The vulnerability found in Mitel MiVoice Connect is a Remote Code Execution (RCE) issue that arises due to improper data validation. Such vulnerabilities allow unauthorized attackers to execute arbitrary code on susceptible systems. This specific flaw affects the Service Appliances component within the Mitel MiVoice Connect product suite. Exploiting this vulnerability can give attackers control over affected appliances, posing significant risks. When left unpatched, RCE vulnerabilities can severely compromise system integrity and data security. Addressing these vulnerabilities promptly is crucial to maintaining enterprise communication security.

The vulnerability details show that the Service Appliance component does not properly validate incoming data, allowing attackers to manipulate system processes. This misconfiguration provides an entry point for executing arbitrary code. The endpoint or parameter that is vulnerable is associated with the handling of data requests in the Service Appliances. Specific appliances affected include the SA 100, SA 400, and Virtual SA, which are key components of the Mitel MiVoice Connect service infrastructure. Attackers exploit this by sending crafted requests to vulnerable endpoints. These actions bypass standard security protocols, leading to unauthorized command execution.

Exploitation of this vulnerability can lead to severe consequences, including unauthorized access to sensitive information and disruption of communication services. Attackers can use the RCE flaw to take control of the underlying system, potentially leading to data breaches or system compromises. This could result in significant operational disruptions, particularly in environments where voice communication is critical. Moreover, there is the possibility of installing malware or other malicious services, further threatening network security. Ultimately, the impact of such exploitation could extend to financial losses and damage to organizational reputation.
