Product Details
Product: INIM SmartLiving
Vendor: INIM Electronics
Category: Integrated intrusion detection, alarm management, and building automation platform
Typical Use Cases: Homes, offices, factories, warehouses, and critical infrastructure
Deployment Nature: Always-on, trusted internal device with deep access to physical security and internal networks
Because SmartLiving systems directly control alarms, sensors, and automation logic, any security weakness has real-world physical and network consequences, not just IT risk.
Vulnerability Overview Table
| CVE ID | Vulnerability | CVSS Score | Severity | Exploitability | Authentication |
|---|---|---|---|---|---|
| CVE-2019-25291 | Hard-coded Credentials | 9.8 | Critical | Very High | Not Required |
| CVE-2019-25290 | Unauthenticated SSRF | 9.6 | Critical | Very High | Not Required |
CVE-2019-25291 – Hard-coded Credentials
High-Level Summary
CVE ID: CVE-2019-25291
CVSS v3 Score: 9.8
Severity: Critical
Exploit Availability: Actively exploitable using standard tools
Attack Complexity: Low
This issue exists because INIM SmartLiving firmware includes fixed usernames and passwords that are the same on every affected device. These credentials are embedded at the firmware level and cannot be removed or rotated by system owners.
Once these credentials became known, any unpatched SmartLiving system effectively became unlocked.
Technical Breakdown
- Credentials are hard-coded inside the firmware image
- Used by service, maintenance, or backend components
- Not visible in the normal UI but accepted by authentication mechanisms
- Credentials persist even after:
- Reboots
- Factory resets
- Configuration changes
This design bypasses all administrator-defined security controls.
Exploitation Flow
- Locate a SmartLiving system on the network or internet
- Access the web interface or service endpoint
- Log in using the known hard-coded credentials
- Gain elevated or full administrative access
- Maintain persistent access without detection
No brute force, phishing, or user interaction is required.
What an Attacker Can Do After Access
- Disable or silence alarms
- Modify automation rules (doors, lights, sensors)
- Create hidden user accounts
- Extract network configuration and credentials
- Use the device as a foothold to attack other systems
Because these systems are trusted internally, attackers can move quietly and persist long-term.
MITRE ATT&CK Techniques
- T1078 – Valid Accounts
- T1552.001 – Credentials Stored in Files
- T1021 – Remote Services
- T1046 – Network Service Discovery
Detection & Monitoring Guidance
What to Watch For
- Logins from IP addresses outside the trusted admin network
- Logins using service or maintenance-style accounts
- Successful logins without any prior failed attempts
- Configuration changes during off-hours
Relevant Log Sources
- SmartLiving authentication and audit logs
- Web server access logs
- Firewall inbound connection logs
- Network intrusion detection systems
Detection Logic
- Alert when non-human or service accounts log in interactively
- Alert when admin access originates from new IP ranges
- Alert when configuration exports or firmware functions are accessed unexpectedly
Remediation & Official Patch
Status: Fixed by vendor firmware update
Official Patch Link:

Temporary Risk Reduction (If Patch Cannot Be Applied Immediately)
- Block all external access to the device
- Restrict management interfaces to a dedicated admin VLAN
- Require VPN access for administrators
- Closely monitor all authentication events
CVE-2019-25290 – Unauthenticated Server-Side Request Forgery (SSRF)
High-Level Summary
CVE ID: CVE-2019-25290
CVSS v3 Score: 9.6
Severity: Critical
Exploit Availability: Practical and repeatable
Attack Complexity: Low
This vulnerability allows any unauthenticated user to make the SmartLiving system send network requests to attacker-chosen destinations. The device effectively acts as a trusted internal proxy.
Technical Breakdown
- A network-facing endpoint accepts user-supplied URLs or IP addresses
- No authentication or authorization checks are enforced
- No validation of destination IP ranges
- Requests are made using the device’s internal network privileges
This enables access to systems that are otherwise unreachable from outside.
Exploitation Flow
- Attacker sends a crafted request to the vulnerable endpoint
- The request contains an internal IP or hostname
- SmartLiving makes the request on behalf of the attacker
- Response behavior reveals internal services and data
This can be automated to scan entire internal networks.

http://192.168.0.1/admin
http://10.0.0.10:443
Real-World Abuse Scenarios
- Internal port scanning
- Access to internal admin panels
- Firewall and NAT bypass
- Lateral movement preparation
- Chaining with credential flaws for full takeover
MITRE ATT&CK Techniques
- T1190 – Exploit Public-Facing Application
- T1090 – Proxy
- T1046 – Network Service Discovery
- T1021 – Remote Services
Detection & Monitoring Guidance
What to Watch For
- Outbound connections to private IP ranges
- Unusual DNS queries from the device
- Repeated short-lived outbound connections
- Traffic to unexpected ports or protocols
Relevant Log Sources
- SmartLiving application logs
- Firewall egress logs
- NetFlow or traffic telemetry
- IDS/IPS alerts
Detection Logic
- Alert when device communicates with RFC1918 IP ranges
- Alert when outbound connections exceed normal baselines
- Alert on URLs containing raw IP addresses in parameters
Remediation & Official Patch
Status: Fixed by vendor firmware update
Official Patch Link:
https://www.inim.biz/en/download/firmware
Temporary Risk Reduction (If Patch Cannot Be Applied Immediately)
- Enforce strict outbound firewall rules
- Allow communication only to required services
- Place device in a tightly restricted VLAN
- Monitor all outbound traffic continuously
Overall Security Risk
These two vulnerabilities together create a worst-case scenario:
- Hard-coded credentials provide guaranteed access
- SSRF enables deep internal network exploration
- Combined impact allows full system and network compromise
Immediate firmware updates and network isolation are strongly recommended.
