CVE-2026-67367: Siemens Simove Fleetmanager v3.1

High severity, CVSS 8.6. EPSS: 1.1% chance of exploitation in the next 30 days.

A vulnerability has been identified in SIMOVE Fleetmanager V3.1 (All versions < V3.1.13), SIMOVE Fleetmanager V3.2 (All versions < V3.2.4), SIMOVE Fleetmanager V3.3 (All versions < V3.3.2), SIMOVE Fleetmanager V4.0 (All versions < V4.0.1), SIPLANT V1.7 (All versions), SIPLANT V2.2 (All versions), SIPLANT V3.0 (All versions), SIPLANT V3.1 (All versions < V3.1.4). Affected devices do not properly validate and neutralize directory traversal sequences in the file-serving endpoint of the embedded HTTP server. This could allow an unauthenticated remote attacker to read arbitrary files from the underlying operating system without any credentials, potentially exposing sensitive data such as credential stores, private keys, and configuration secrets.
