CVE-2025-10653: Debug Port Information Disclosure Flaw

CVE-2025-10653 Overview

CVE-2025-10653 is an authentication bypass vulnerability [CWE-288] involving an unauthenticated debug port that exposes the device file system to remote attackers. The flaw was disclosed through CISA ICS Advisory ICSA-25-275-01, which addresses Raise3D 3D printer products. An attacker with network reachability to the affected device can connect to the debug interface without supplying credentials and read or interact with files stored on the device. The issue carries a network attack vector and requires no user interaction or prior privileges.

Critical Impact

A remote, unauthenticated attacker can access the device file system through an exposed debug port, enabling exposure of configuration, firmware, and operational data.

Technical Details for CVE-2025-10653

Vulnerability Analysis

The vulnerability stems from a debug interface that remains accessible on a network-reachable port without enforcing any authentication. Debug ports are typically intended for engineering use during development and manufacturing. Leaving them enabled in production firmware exposes privileged device functionality to any client capable of reaching the listening service.

Once connected, an attacker can navigate and read the underlying file system of the device. This grants visibility into firmware components, configuration files, logs, and potentially credentials or API tokens stored locally. The vulnerability is classified under [CWE-288] Authentication Bypass Using an Alternate Path or Channel, because the debug port serves as a parallel access route that bypasses the authenticated management interface.

The Exploit Prediction Scoring System (EPSS) probability is 0.065% with a percentile of 19.95, and no public exploit code or CISA KEV listing is currently associated with this CVE.

Root Cause

The root cause is a design and configuration flaw: a diagnostic service exposed over the network does not require credentials, certificates, or any other access control. The debug channel was not gated behind the device's primary authentication boundary, creating an alternate path to sensitive resources.

Attack Vector

Exploitation requires only network access to the debug port on the affected device. An attacker scans for the listening service, establishes a session, and issues file system commands supported by the debug protocol. No phishing, credential theft, or local presence is needed. Devices exposed to the internet or shared operational technology networks are most at risk. See the CISA ICS Advisory ICSA-25-275-01 for protocol-level technical details.

Detection Methods for CVE-2025-10653

Indicators of Compromise

• Unexpected inbound TCP connections to debug or diagnostic service ports on affected devices
• File access patterns or command sequences in device logs that originate from non-administrative sources
• Outbound transfers of configuration or firmware artifacts from the device to unknown hosts

Detection Strategies

• Perform authenticated network scans of operational technology segments to enumerate exposed debug services
• Inspect device firmware and running services for diagnostic listeners that lack authentication
• Correlate network flow data to identify external or unauthorized internal hosts contacting affected devices

Monitoring Recommendations

• Forward device and network telemetry to a centralized SIEM such as Singularity Data Lake for cross-source correlation
• Alert on any new connections to non-standard ports on 3D printers and other ICS endpoints
• Track file system read patterns and configuration access events for anomalies

How to Mitigate CVE-2025-10653

Immediate Actions Required

• Identify all Raise3D devices listed in CISA ICS Advisory ICSA-25-275-01 and inventory their network exposure
• Block external network access to the debug port at the perimeter and segment affected devices on isolated VLANs
• Apply vendor firmware updates as soon as they are released by Raise3D

Patch Information

Consult the Raise3D Support Page for the latest firmware and remediation guidance. At time of NVD publication, refer to the vendor advisory for affected version ranges and fixed builds.

Workarounds

• Restrict device management to a dedicated administrative network with no internet routing
• Place affected devices behind a firewall that denies all inbound traffic to the debug service port
• Disable the debug interface in device settings if vendor configuration permits
• Monitor for unauthorized connections using IDS signatures aligned to the debug protocol

# Example firewall rule to block external access to a debug port
# Replace <DEBUG_PORT> with the port identified in the vendor advisory
iptables -A INPUT -p tcp --dport <DEBUG_PORT> -s 0.0.0.0/0 -j DROP
iptables -A INPUT -p tcp --dport <DEBUG_PORT> -s 10.0.0.0/8 -j ACCEPT
