CVE-2026-11849: IRM-IEI Remote Management Hardcoded Credentials

Executive Summary

CVE-2026-11849 is a critical hardcoded credentials vulnerability (CVSS 9.8) in the iRM-IEI Remote Management software developed by IEI Integration Corp. An unauthenticated remote attacker can exploit the hard-coded credentials embedded in the application to gain full administrative privileges on the database, without needing to know or brute-force any legitimate credentials. This type of vulnerability represents a fundamental security failure in embedded system management software and is trivially exploitable across any network-accessible deployment.

Vulnerability Details

Technical Analysis

Root Cause

The iRM-IEI Remote Management software contains hard-coded credentials embedded directly within the application binary or configuration. These credentials — which are identical across all deployments — allow any attacker with network access to authenticate directly to the underlying database management layer using the baked-in username and password.

Hard-coded credentials (CWE-798) represent a class of vulnerability that is particularly severe in management software because:

1. The credentials cannot be changed by the end user without modifying the software itself
2. The credentials are identical across all deployments — discovering them once provides access to every installation
3. No authentication bypass is required — the attacker simply uses the known credentials as legitimate authentication

Attack Scenario

Attacker discovers IRM-IEI Remote Management on network
  ↓
Attacker uses publicly known hardcoded credential pair
  ↓
Full authenticated database admin session granted
  ↓
Read/write/delete access to all managed data

Impact Assessment

An attacker successfully exploiting this vulnerability can:

• Read all data stored in the IRM-IEI managed database — including device configurations, user accounts, management credentials, and any sensitive operational data
• Modify database records — alter device configurations, disable security controls, or insert malicious data
• Delete data — destroy audit logs, configuration records, or other critical operational data
• Pivot to managed devices — if the IRM-IEI platform manages industrial or embedded devices (common in IEI's product portfolio), administrative database access may enable lateral movement to those endpoints

Affected Products

IEI Integration Corp's iRM-IEI Remote Management software is part of IEI's broader industrial computing and embedded systems management portfolio. IEI produces industrial motherboards, rackmount servers, panel PCs, and related embedded computing hardware — iRM-IEI is the remote management layer for these devices.

Organizations running IEI hardware in:

• Industrial control environments
• Manufacturing facilities
• Healthcare IT infrastructure
• Retail and point-of-sale deployments
• Transportation and logistics systems

should assess their exposure immediately.

Remediation

Immediate Actions

1. Apply the vendor patch — Check IEI Integration Corp's security advisories and product update pages for a patched version of iRM-IEI Remote Management that removes or mitigates the hardcoded credentials
2. Restrict network access — Until a patch is available and applied, restrict access to the iRM-IEI management interface to trusted IP ranges using firewall rules or network segmentation
3. Audit access logs — Review logs for any connections to the iRM-IEI management interface from unexpected sources; anomalous authentication events using the default credentials indicate active exploitation

Network Controls (Pre-Patch Mitigation)

# Example firewall approach: allow only management VLAN
iptables -A INPUT -p tcp --dport <IRM_PORT> -s <MGMT_VLAN_CIDR> -j ACCEPT
iptables -A INPUT -p tcp --dport <IRM_PORT> -j DROP

Long-Term Hardening

• Inventory IRM-IEI deployments across your environment — identify all systems running the software
• Implement network segmentation for industrial management interfaces, ensuring they are not reachable from general enterprise networks or the internet
• Establish a patch management process for IEI products, subscribing to IEI's security advisory notifications

Detection

Network-Based Detection

Look for unexpected authentication attempts or connections to ports associated with iRM-IEI Remote Management. Any successful database authentication from external IP addresses warrants immediate investigation.

Host-Based Detection

# Check for active iRM-IEI processes
ps aux | grep -i irm
 
# Review recent database authentication events
# (path varies by deployment)
grep -i "auth" /var/log/irm-iei/*.log 2>/dev/null

SIEM Detection Logic

Alert on:

• Database authentication from IP addresses outside the authorized management range
• Authentication using default/known credential strings
• Off-hours connections to the iRM-IEI management port
