CVE-2022-44153 is a Cross Site Scripting (XSS) vulnerability identified in Rapid Software LLC's Rapid SCADA version 5.8.4. Rapid SCADA is an open-source Supervisory Control and Data Acquisition (SCADA) system used for industrial automation and control. The vulnerability is classified under CWE-79, indicating that it arises from improper neutralization of input during web page generation, allowing an attacker to inject malicious scripts into web pages viewed by other users. Specifically, this vulnerability allows remote attackers to execute arbitrary scripts in the context of the affected web application by tricking a user into interacting with crafted input, as user interaction is required (UI:R). The CVSS 3.1 base score is 6.1 (medium severity), with an attack vector of network (AV:N), low attack complexity (AC:L), no privileges required (PR:N), user interaction required (UI:R), scope changed (S:C), and impacts on confidentiality and integrity (C:L/I:L) but no impact on availability (A:N). The scope change indicates that the vulnerability affects components beyond the initially vulnerable component, potentially impacting other parts of the system or connected systems. Although no known exploits are reported in the wild, the vulnerability poses a risk of session hijacking, credential theft, or unauthorized actions performed on behalf of legitimate users. Since Rapid SCADA is used in industrial environments, exploitation could lead to manipulation of control data or unauthorized access to sensitive operational information. The lack of vendor or product details and absence of patch links in the provided information suggests that users should verify the availability of updates or mitigations directly from Rapid Software LLC or trusted sources. The vulnerability was published on December 7, 2022, and reserved on October 30, 2022, indicating recent discovery and disclosure.

For European organizations, especially those operating in critical infrastructure sectors such as energy, manufacturing, water treatment, and transportation, this vulnerability could have significant operational and security impacts. Rapid SCADA systems are integral to monitoring and controlling industrial processes; thus, successful exploitation could lead to unauthorized manipulation of control commands, data leakage, or disruption of monitoring capabilities. Although the vulnerability does not directly impact availability, the compromise of confidentiality and integrity could undermine trust in system data, cause erroneous operational decisions, or facilitate further attacks such as privilege escalation or lateral movement within industrial networks. Given the interconnected nature of European industrial environments and the increasing digitization of operational technology (OT), exploitation could have cascading effects across supply chains and critical services. Additionally, regulatory frameworks such as the NIS Directive and GDPR impose strict requirements on the security and privacy of industrial systems and data, so exploitation could also lead to compliance violations and reputational damage.

1. Immediate assessment of Rapid SCADA 5.8.4 deployments within the organization to identify exposed instances. 2. Apply any available patches or updates from Rapid Software LLC as soon as they are released; if no official patch exists, consider implementing web application firewalls (WAF) with custom rules to detect and block XSS payloads targeting Rapid SCADA interfaces. 3. Conduct input validation and output encoding on all user-supplied data within the SCADA web interface to prevent injection of malicious scripts. 4. Restrict access to the SCADA web interface to trusted networks and authenticated users only, employing network segmentation and VPNs to reduce exposure. 5. Implement Content Security Policy (CSP) headers to limit the execution of unauthorized scripts in the browser context. 6. Educate users on the risks of interacting with untrusted links or inputs within the SCADA environment to reduce the likelihood of successful social engineering. 7. Monitor logs and network traffic for anomalous activities indicative of attempted XSS exploitation or unauthorized access. 8. Engage with Rapid Software LLC or the user community for updates, advisories, and best practices specific to this vulnerability. 9. Consider deploying endpoint protection solutions capable of detecting script-based attacks on operator workstations accessing the SCADA system.
