# CVE-2023-2917: Rockwell Automation ThinManager Thinserver Software Vulnerable to Input Validation Vulnerability

- Severity: CVSS 9.8 (Critical), CNA
- Vector: CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H
- CISA SSVC: exploitation=none, automatable=yes, technicalImpact=total
- Known exploited (CISA KEV): no
- Public exploit code: 1 Metasploit module
- Published: 2023-08-17 · Updated: 2024-10-08

## Affected

- Rockwell Automation ThinManager ThinServer: 11.0.0 - 11.2.6, 11.1.0 - 11.1.6, 11.2.0 - 11.2.7, 12.0.0 - 12.0.5, 12.1.0 - 12.1.6, 13.0.0 - 13.0.2, 13.1.0

## Description

The Rockwell Automation Thinmanager Thinserver is impacted by an improper input validation vulnerability. Due to an improper input validation, a path traversal vulnerability exists, via the filename field, when the ThinManager processes a certain function. If exploited, an unauthenticated remote attacker can upload arbitrary files to any directory on the disk drive where ThinServer.exe is installed. A malicious user could exploit this vulnerability by sending a crafted synchronization protocol message and potentially gain remote code execution abilities.

## What to do
