CVE-2024-24398 is a critical directory traversal vulnerability identified in Stimulsoft GmbH's Stimulsoft Dashboard.JS product versions prior to 2024.1.2. This vulnerability arises from improper validation of the 'fileName' parameter in the Save function, which allows a remote attacker to craft a malicious payload that manipulates the file path. By exploiting this flaw, an attacker can traverse directories outside the intended file storage location, potentially leading to arbitrary code execution on the affected system. The vulnerability is classified under CWE-22 (Improper Limitation of a Pathname to a Restricted Directory), indicating that the software fails to adequately restrict file paths to safe directories. The CVSS v3.1 base score is 9.8, reflecting a critical severity level due to the vulnerability's characteristics: it is remotely exploitable over the network without any authentication or user interaction, and it impacts confidentiality, integrity, and availability. Successful exploitation could allow attackers to execute arbitrary code, leading to full system compromise, data theft, or service disruption. No known exploits are currently reported in the wild, and no vendor patches or mitigations have been explicitly linked in the provided data, though the fixed version is 2024.1.2 or later. Given the nature of the vulnerability, it is likely that attackers could leverage this flaw to deploy malware, ransomware, or pivot within compromised networks.

For European organizations, the impact of CVE-2024-24398 could be severe, especially for those using Stimulsoft Dashboard.JS in their business intelligence, reporting, or data visualization workflows. Exploitation could lead to unauthorized access to sensitive business data, intellectual property theft, or disruption of critical dashboard services that support decision-making processes. The ability to execute arbitrary code remotely without authentication significantly raises the risk profile, potentially enabling attackers to establish persistent footholds or move laterally within corporate networks. This could affect sectors such as finance, manufacturing, healthcare, and government agencies that rely on Stimulsoft products for data analytics. Additionally, the breach of confidentiality and integrity could result in regulatory non-compliance under GDPR, leading to legal and financial penalties. The availability impact could disrupt operational continuity, causing downtime and loss of productivity. The absence of known public exploits provides a window for proactive mitigation, but the critical severity demands immediate attention to prevent potential targeted attacks.

European organizations should prioritize upgrading Stimulsoft Dashboard.JS to version 2024.1.2 or later, where this vulnerability is addressed. In the absence of an immediate patch, organizations should implement strict input validation and sanitization on the 'fileName' parameter at the application or web server level to prevent directory traversal attempts. Employing Web Application Firewalls (WAFs) with custom rules to detect and block suspicious payloads targeting file path parameters can provide an additional protective layer. Network segmentation should be enforced to limit access to systems running vulnerable versions, reducing the attack surface. Monitoring and logging file access patterns and unusual process executions can help detect exploitation attempts early. Organizations should also conduct vulnerability scanning and penetration testing focused on this vulnerability to identify exposure. Finally, maintaining an incident response plan that includes procedures for containment and remediation of code execution incidents is essential.
