SIMOVE Fleetmanager V3.1: Relative Path Traversal

CVE-2026-67367 is a high-severity relative path traversal vulnerability in SIMOVE Fleetmanager V3.1 from Siemens, with a CVSS 3.1 base score of 8.6 out of 10. It can be exploited remotely over the network by an unauthenticated attacker, without any action from a user. The record lists version V3.1.13 as the first without the flaw, so updating SIMOVE Fleetmanager V3.1 to that release or later removes the exposure. There is no confirmed exploitation so far. EPSS estimates a 1.11% chance of exploitation within 30 days, higher than 66% of scored CVEs.

Next patch cycle

High severity with no evidence of exploitation so far.

What to do

  1. Update SIMOVE Fleetmanager V3.1 to V3.1.13 or a later version.
  2. Update SIMOVE Fleetmanager V3.2 to V3.2.4 or a later version.
  3. Update SIMOVE Fleetmanager V3.3 to V3.3.2 or a later version.
  4. Until you can update, restrict network access to the affected service so it is not reachable from untrusted networks.

Official description

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.

Source: the CVE record as published by its numbering authority, via NVD and CVE.org.

The underlying weakness: Relative Path Traversal

The product uses external input to construct a pathname that should be within a restricted directory, but it does not properly neutralize sequences such as.. that can resolve to a location that is outside of that directory.

How developers prevent this class of flaw

  • Use an application firewall that can detect attacks against this weakness. It can be beneficial in cases in which the code cannot be fixed (because it is controlled by a third party), as an emergency prevention measure while more comprehensive software assurance measures are applied, or to provide defense in depth.
