Description Preview
A path traversal vulnerability (CWE-22) exists in Rockwell Automation's ThinManager ThinServer when processing a message of type 8. This vulnerability allows an unauthenticated remote attacker to download arbitrary files from the disk drive where ThinServer.exe is installed, potentially exposing sensitive information or system files.
Overview
The vulnerability affects Rockwell Automation's ThinManager ThinServer application. The path traversal flaw occurs during the processing of type 8 messages, which allows attackers to navigate outside of the intended directory structure. Since this vulnerability can be exploited by unauthenticated remote attackers, it presents a significant security risk to affected systems. Successful exploitation could lead to unauthorized access to sensitive files, exposure of configuration data, credentials, or other critical information stored on the same drive as the ThinServer application.
Remediation
Users of affected Rockwell Automation ThinManager ThinServer versions should:
- Update to the latest version of the software as provided by Rockwell Automation
- If immediate patching is not possible, consider implementing network segmentation to limit remote access to the ThinServer
- Monitor system logs for unusual file access patterns
- Follow the specific mitigation guidance provided in Rockwell Automation's security advisory
- Conduct a security assessment to determine if the vulnerability has been previously exploited
