CVE-2022-22522 is a critical security vulnerability identified in Carlo Gavazzi's UWP 3.0 Monitoring Gateway and Controller, as well as the CPY Car Park Server version 2.8.3. The core issue is the presence of hard-coded credentials embedded within the affected devices' firmware or software. This vulnerability falls under CWE-798, which pertains to the use of hard-coded passwords or cryptographic keys. Because these credentials are hard-coded and not unique per device or user, an attacker can remotely exploit this flaw without any authentication or user interaction. The CVSS v3.1 base score of 9.8 reflects the severity, indicating that the vulnerability is remotely exploitable over the network (AV:N), requires no privileges (PR:N), no user interaction (UI:N), and impacts confidentiality, integrity, and availability to a high degree (C:H/I:H/A:H). Exploiting this vulnerability would allow an attacker to gain full administrative access to the device, enabling them to manipulate device configurations, disrupt operations, or pivot into the broader network environment. The affected product, UWP 3.0 Monitoring Gateway and Controller, is typically used in industrial automation and building management systems, which are critical infrastructure components. Although no public exploits have been reported in the wild yet, the nature of the vulnerability and the critical CVSS score suggest that it is a high-value target for attackers. The lack of available patches at the time of reporting further exacerbates the risk. The vulnerability was officially published on September 28, 2022, and assigned by CERTVDE, indicating recognized severity and the need for urgent remediation.

For European organizations, the impact of CVE-2022-22522 can be substantial, especially for those operating in sectors reliant on industrial automation, building management, and smart infrastructure, such as manufacturing plants, commercial real estate, and parking management systems. Successful exploitation could lead to unauthorized control over critical systems, resulting in operational disruptions, safety hazards, and potential data breaches. Given the high confidentiality, integrity, and availability impact, attackers could manipulate sensor data, disable safety mechanisms, or cause denial of service conditions. This could lead to financial losses, regulatory non-compliance (especially under GDPR if personal data is involved), and reputational damage. Additionally, compromised devices could serve as entry points for lateral movement within enterprise networks, increasing the risk of broader cyberattacks. European organizations with interconnected operational technology (OT) and IT environments are particularly vulnerable, as this vulnerability bridges those domains. The absence of authentication requirements and the remote exploitability make it easier for attackers to target these devices from anywhere, increasing the threat landscape. The lack of known exploits in the wild does not diminish the urgency, as threat actors often weaponize such vulnerabilities rapidly once disclosed.

To mitigate the risks posed by CVE-2022-22522, European organizations should take immediate and specific actions beyond generic advice: 1) Inventory and Identify: Conduct a thorough asset inventory to identify all instances of Carlo Gavazzi UWP 3.0 Monitoring Gateway and Controller devices and CPY Car Park Server version 2.8.3 within the network. 2) Network Segmentation: Isolate affected devices on dedicated network segments with strict access controls to limit exposure to untrusted networks and reduce attack surface. 3) Access Controls: Implement firewall rules and network access control lists (ACLs) to restrict inbound and outbound traffic to and from these devices only to trusted management systems and personnel. 4) Vendor Engagement: Engage with Carlo Gavazzi to obtain any available patches, firmware updates, or recommended configuration changes. If no patches are available, request guidance on temporary workarounds such as disabling vulnerable services or changing default credentials if possible. 5) Monitoring and Detection: Deploy network monitoring and intrusion detection systems (IDS) tuned to detect anomalous activities targeting these devices, including unauthorized login attempts or unusual command executions. 6) Incident Response Preparedness: Develop and test incident response plans specifically addressing potential compromise of these devices, including containment and recovery procedures. 7) Physical Security: Ensure physical security controls are in place to prevent unauthorized local access to the devices. 8) Long-term Replacement: Plan for phased replacement or upgrade of vulnerable devices with versions that do not contain hard-coded credentials or that support secure authentication mechanisms. These steps, combined, will reduce the likelihood of exploitation and limit potential damage if an attack occurs.
