TRCore DVC - Willekeurig Bestand Lezen via Path Traversal

The impact of this Path Traversal vulnerability is significant due to its ease of exploitation and the potential for data exposure. An attacker could leverage this flaw to read critical system files, including configuration files containing passwords, API keys, or other sensitive credentials. Successful exploitation could lead to unauthorized access to the underlying system, enabling further malicious activities such as data theft, system compromise, or denial of service. The ability to read arbitrary files also presents a risk of intellectual property theft, as attackers could potentially access proprietary code or design documents.

Industrial control systems utilizing TRCore DVC versions 6.0 through 6.3 are at significant risk. This includes organizations in sectors such as manufacturing, energy, and utilities that rely on DVC for data acquisition and control. Legacy systems and those with limited security patching capabilities are particularly vulnerable.

• other / system: Monitor system logs for unusual file access patterns, particularly attempts to access files outside of expected directories. Look for requests containing '..' sequences in the file path. • other / system: Implement file integrity monitoring (FIM) to detect unauthorized modifications to critical system files. • other / system: Review network traffic for suspicious requests targeting the DVC component, focusing on those containing unusual file paths.

The primary mitigation for CVE-2024-11309 is to upgrade to TRCore DVC version 6.3.1 or later, which contains the fix. If immediate upgrading is not possible, consider implementing temporary workarounds to restrict file access. This could involve configuring the DVC component to only allow access to specific, authorized files and directories. Implement strict input validation to prevent attackers from manipulating file paths. Regularly monitor system logs for suspicious activity, such as attempts to access unauthorized files. Consider deploying a Web Application Firewall (WAF) to filter malicious requests.
