CVE-2022-44606 is a high-severity OS command injection vulnerability affecting UNIMO Technology Co., Ltd devices specifically the UDR-JA1604, UDR-JA1608, and UDR-JA1616 models running firmware versions 71x10.1.107112.43A and earlier. This vulnerability arises from improper sanitization of user-supplied input that is passed to operating system commands, classified under CWE-78 (Improper Neutralization of Special Elements used in an OS Command). An authenticated remote attacker can exploit this flaw to execute arbitrary OS commands on the affected device, potentially leading to full compromise of the device. The attacker can also alter device settings, which may disrupt normal operations or facilitate persistent access. The CVSS v3.1 base score is 8.8, reflecting high impact on confidentiality, integrity, and availability. The attack vector is network-based (AV:N), requiring low attack complexity (AC:L) and only low privileges (PR:L) but no user interaction (UI:N). The scope is unchanged (S:U), meaning the impact is confined to the vulnerable device. Although no public exploits are currently known in the wild, the vulnerability poses a significant risk due to the ease of exploitation once authenticated access is obtained. The lack of available patches at the time of reporting increases exposure. Given the nature of the devices—likely network or industrial equipment—the ability to execute arbitrary commands remotely could lead to device takeover, data leakage, service disruption, or use as a pivot point within a network.

For European organizations, this vulnerability could have severe consequences, especially for those relying on UNIMO UDR series devices in critical infrastructure, industrial control systems, or enterprise network environments. Successful exploitation could lead to unauthorized control over network devices, resulting in disruption of services, manipulation of device configurations, and potential lateral movement within corporate or industrial networks. Confidential information stored or processed by these devices could be exposed or altered, undermining data integrity and confidentiality. The availability of critical network functions could be compromised, impacting business continuity and operational safety. Given the high CVSS score and the ability to execute arbitrary commands remotely with only authenticated access, organizations face a significant risk of targeted attacks, especially if attackers gain credentials through phishing or insider threats. The absence of known public exploits may reduce immediate risk but does not eliminate the threat, as attackers could develop exploits rapidly. The impact is particularly critical for sectors such as manufacturing, energy, telecommunications, and transportation, where such devices might be deployed.

1. Immediate firmware upgrade: Organizations should verify the firmware version of their UNIMO UDR-JA1604, UDR-JA1608, and UDR-JA1616 devices and upgrade to the latest firmware version once available from the vendor. 2. Restrict administrative access: Limit remote management interfaces to trusted IP addresses and networks using firewall rules or VPNs to reduce exposure. 3. Enforce strong authentication: Implement multi-factor authentication (MFA) for device access to mitigate risks from compromised credentials. 4. Network segmentation: Isolate these devices in dedicated network segments with strict access controls to prevent lateral movement in case of compromise. 5. Monitor logs and network traffic: Enable detailed logging on the devices and monitor for unusual command execution patterns or configuration changes indicative of exploitation attempts. 6. Credential hygiene: Regularly rotate device credentials and ensure they are complex and unique. 7. Incident response readiness: Prepare to isolate or take affected devices offline quickly if exploitation is suspected. 8. Vendor engagement: Engage with UNIMO Technology for timely patch releases and security advisories. 9. Conduct penetration testing and vulnerability assessments focused on these devices to identify potential exploitation paths. These measures go beyond generic advice by focusing on access control, monitoring, and network architecture adjustments tailored to the specific device and vulnerability characteristics.
