CVE-2022-41870 is a high-severity command injection vulnerability affecting the AP Manager component in Innovaphone products prior to version 13r2 Service Release 17. The vulnerability arises due to insufficient input validation of the service ID parameter during the app upload process. An attacker with high privileges can modify the service ID to inject arbitrary commands, which the system then executes. This type of vulnerability is classified under CWE-77 (Improper Neutralization of Special Elements used in a Command). The CVSS v3.1 base score is 7.2, indicating a high impact with network attack vector, low attack complexity, requiring privileges but no user interaction, and resulting in high confidentiality, integrity, and availability impacts. Although no known exploits are currently reported in the wild, the potential for exploitation exists given the nature of command injection flaws. The lack of available patches at the time of reporting increases the urgency for affected organizations to implement mitigations. The vulnerability allows an attacker to execute arbitrary commands on the underlying system, potentially leading to full system compromise, data theft, service disruption, or lateral movement within the network.

For European organizations, particularly those using Innovaphone communication solutions, this vulnerability poses a significant risk. Exploitation could lead to unauthorized command execution on critical telephony infrastructure, potentially disrupting voice communications, compromising sensitive call data, and enabling attackers to pivot to other internal systems. Given the reliance on unified communications in sectors such as finance, healthcare, government, and critical infrastructure, the impact could extend to operational downtime, data breaches involving personal or confidential information, and regulatory non-compliance under GDPR. The high integrity and availability impact means that business continuity could be severely affected. Additionally, the requirement for high privileges to exploit the vulnerability suggests that insider threats or attackers who have already gained some access could escalate their control rapidly.

Organizations should prioritize upgrading Innovaphone AP Manager to version 13r2 Service Release 17 or later, where the vulnerability is addressed. In the absence of an immediate patch, restrict access to the AP Manager interface to trusted administrators only, ideally via VPN or secure management networks. Implement strict input validation and sanitization controls on service ID parameters if custom integrations or scripts are used. Monitor logs for unusual app upload activities or service ID modifications. Employ network segmentation to isolate telephony management systems from general user networks. Conduct regular privilege audits to ensure that only necessary personnel have high-level access. Additionally, consider deploying intrusion detection systems tuned to detect command injection patterns and anomalous command executions on affected hosts.
