CVE-2025-40948: Siemens RUGGEDCOM ROX MX5000 — Improper Neutralization of Argument Delimiters in a Command ('Argument Injection')

Recommended actionScheduled

Medium technical severity with no CISA KEV confirmation; remediate through the normal risk-based patch cycle unless local exposure raises the priority.

What, why and how

A vulnerability has been identified in RUGGEDCOM ROX MX5000 (All versions < V2.17.1), RUGGEDCOM ROX MX5000RE (All versions < V2.17.1), RUGGEDCOM ROX RX1400 (All versions < V2.17.1), RUGGEDCOM ROX RX1500 (All versions < V2.17.1), RUGGEDCOM ROX RX1501 (All versions < V2.17.1), RUGGEDCOM ROX RX1510 (All versions < V2.17.1), RUGGEDCOM ROX RX1511 (All versions < V2.17.1), RUGGEDCOM ROX RX1512 (All versions < V2.17.1), RUGGEDCOM ROX RX1524 (All versions < V2.17.1), RUGGEDCOM ROX RX1536 (All versions < V2.17.1), RUGGEDCOM ROX RX5000 (All versions < V2.17.1). Affected devices do not properly validate input in the web server's JSON-RPC interface. This could allow an authenticated remote attacker to read arbitrary files from the underlying operating system's filesystem with root privileges.

What

Why

The product constructs a string for a command to be executed by a separate component in another control sphere, but it does not properly delimit the intended arguments, options, or switches within that command string.

How

An attacker operating through a network path may attempt exploitation with elevated privileges. If successful, the issue may obtain information outside the intended access boundary.

Why

How

Exploit reality and attack path

CVSS severity, EPSS forecast probability, public exploit material and CISA-confirmed exploitation are separate signals.

Observed exploitation

Confirmed exploitation and public exploit material are separate signals. Attacks can occur without public proof-of-concept or exploit code.

No confirmed evidence

No CISA KEV match was present at the last successful refresh. This means no confirmation from that source, not proof of no exploitation.

Public PoC / exploit material

Confirmed exploitation and public exploit material are separate signals. Attacks can occur without public proof-of-concept or exploit code.

None recorded

No exploit-tagged reference or CISA SSVC proof-of-concept state is currently recorded. Research may still exist outside the structured feeds.

Likely attack path: a network path → Improper Neutralization of Argument Delimiters in a Command ('Argument Injection') → obtain information outside the intended access boundary
Attack surface: Network
Privileges required: High: elevated access is required
User interaction: None
Attack complexity: Low: no specialised conditions are recorded
Security boundary: Not a CVSS 4.0 base metric
Weakness ? CWE means Common Weakness Enumeration: a standard category for the underlying weakness.: CWE-88 ↗
