Impact Analysis

An attacker exploiting this vulnerability can read any file on the server running the Golem OEE MES software if they are on the same local network. This could lead to exposure of sensitive data stored on the server, potentially compromising system security and confidentiality.

Executive Summary

CVE-2026-8464 is a path traversal vulnerability in the Golem OEE MES software by Neuron Soft. It allows an attacker located in the same local network to read arbitrary files from the server's operating system by manipulating HTTP request paths without needing to authenticate.

This vulnerability affects all versions below 11.6.0 and was fixed in version 11.6.0.

Mitigation Strategies

To mitigate the vulnerability CVE-2026-8464 in Golem OEE MES, you should update the software to version 11.6.0 or later, as this version contains the fix for the unauthenticated path traversal flaw.

Before performing the update, it is recommended to disconnect all running programs and back up your databases to avoid corruption.

Ensure that all components of the system, including mobile applications, are updated since the vulnerability was also addressed in the mobile app packages.

Detection Guidance

This vulnerability can be detected by monitoring HTTP requests on your network or system for suspicious path traversal patterns. Since the flaw allows reading arbitrary files by manipulating HTTP request paths without authentication, you should look for HTTP requests containing sequences like "../" or other directory traversal indicators targeting the Golem OEE MES server.

A practical approach is to capture and analyze HTTP traffic to the Golem OEE MES server using tools such as tcpdump or Wireshark, filtering for HTTP requests with suspicious path traversal patterns.

Example commands to detect such attempts include:

• Using tcpdump to capture HTTP requests containing '../': tcpdump -i <interface> -A -s 0 'tcp port 80 and (((ip[2:2] - ((ip[0]&0xf)<<2)) - ((tcp[12]&0xf0)>>2)) != 0)' | grep '\.\./'
• Using grep on web server logs to find path traversal attempts: grep '\.\./' /path/to/golem_oee_mes/access.log
• Using curl to test the vulnerability manually by sending crafted HTTP requests with path traversal sequences to the server and observing responses.

Note that the vulnerability affects versions below 11.6.0, so verifying the installed version of Golem OEE MES is also important.
