What is CVE-2024-41710?

CVE-2024-41710 is a vulnerability affecting the Mitel 6800 Series, 6900 Series, and 6900w Series SIP Phones, including the 6970 Conference Unit. These devices are widely used in enterprise telecommunication systems for voice over IP (VoIP) communication. The vulnerability arises from insufficient parameter sanitization during the boot process, permitting an authenticated attacker with administrative privileges to execute an argument injection attack. If successfully exploited, this could compromise the functionality of the devices and lead to unauthorized command execution, posing significant risks to organizations utilizing these telephony systems.

Technical Details

The vulnerability is rooted in the way these SIP phones handle parameters during startup. Attackers who already possess administrative access can manipulate the input parameters due to the lack of adequate validation mechanisms. This flaw potentially allows for the execution of arbitrary commands on the affected systems without proper authorization checks, undermining the integrity and security of the devices.

Potential Impact of CVE-2024-41710

Unauthorized Command Execution: Successful exploitation could enable an attacker to execute arbitrary commands within the system context, leading to further system compromise and malicious activities.
Disruption of Telecommunication Services: By gaining control over telephony systems, attackers could disrupt communication channels, affecting business operations and potentially harming organizational reputation.
Increased Attack Surface: This vulnerability could serve as a foothold for broader attacks, allowing attackers to pivot and compromise other systems within the organization's network, leading to larger scale security breaches.

CISA Reported

CISA provides regional cyber and physical services to support security and resilience across the United States. CISA monitor the most dangerious vulnerabilities and have identifed as being exploited but is not known by the CISA to be used in ransomware campaigns. This is subject to change at pace as recent news articles suggest the vulnerability is being used by ransomware groups.

The CISA's recommendation is: Apply mitigations per vendor instructions or discontinue use of the product if mitigations are unavailable.
