CVE-2024-22096 is a medium-severity vulnerability identified in Rapid Software LLC's Rapid SCADA product, specifically in versions prior to 5.8.4. The vulnerability is classified as a CWE-23 Relative Path Traversal flaw. This type of vulnerability allows an attacker to manipulate file path inputs by appending path traversal characters (such as '../') to a filename parameter in a specific command within the Rapid SCADA system. By exploiting this flaw, an attacker with at least low-level privileges (PR:L) but no user interaction required (UI:N) can read arbitrary files on the underlying system. The vulnerability has a CVSS v3.1 base score of 6.5, indicating a medium level of severity. The attack vector is network-based (AV:N), meaning the attacker can exploit the vulnerability remotely over the network. The attack complexity is low (AC:L), so no special conditions are required beyond the attacker having some level of privileges. The impact is primarily on confidentiality (C:H), as the attacker can access sensitive files, but there is no impact on integrity or availability (I:N/A:N). The scope remains unchanged (S:U), meaning the vulnerability affects only the vulnerable component and does not extend to other system components. No known exploits are currently reported in the wild, and no official patches are linked in the provided information, though the vendor has released version 5.8.4 presumably addressing this issue. Rapid SCADA is an industrial control system (ICS) software used for supervisory control and data acquisition, often deployed in critical infrastructure sectors such as energy, water, and manufacturing. The ability to read arbitrary files could expose sensitive configuration files, credentials, or operational data, potentially aiding further attacks or espionage.

For European organizations, especially those operating critical infrastructure or industrial environments using Rapid SCADA, this vulnerability poses a significant risk to confidentiality. Unauthorized disclosure of configuration files or credentials could lead to further compromise, including unauthorized control or disruption of industrial processes. Given the network-based attack vector and low complexity, attackers with limited privileges inside the network could exploit this flaw to escalate their access or gather intelligence. This could impact sectors such as energy utilities, water treatment facilities, manufacturing plants, and transportation systems across Europe. The exposure of sensitive operational data could also have regulatory and compliance implications under GDPR and NIS Directive frameworks, potentially leading to legal and financial consequences. Although no known exploits are reported yet, the presence of this vulnerability in widely used ICS software warrants immediate attention to prevent potential targeted attacks or espionage campaigns.

European organizations using Rapid SCADA should prioritize upgrading to version 5.8.4 or later, where this vulnerability is addressed. In the absence of an immediate patch, organizations should implement strict network segmentation to isolate SCADA systems from general IT networks and limit access to trusted personnel only. Employing robust access controls and monitoring for unusual file access patterns can help detect exploitation attempts. Additionally, organizations should review and harden the configuration of the affected command interfaces to restrict input validation and sanitize file path parameters. Conducting regular vulnerability assessments and penetration testing focused on ICS environments will help identify and remediate similar issues proactively. Finally, maintaining an incident response plan tailored to ICS environments will ensure rapid containment and recovery if exploitation occurs.
