1. Introduction
The Cisco TelePresence Conductor uses default credentials for its web application interface. This means anyone can log in without a username and password, potentially taking full control of the system. This affects businesses using this product as it could lead to complete compromise of the video conferencing infrastructure. Confidentiality, integrity, and availability are all at high risk if exploited.
2. Technical Explanation
The Cisco TelePresence Conductor installation ships with a pre-configured username and password for the web UI. An attacker can exploit this by simply attempting to log in using these default credentials without any authentication required. This allows them to gain administrative access to the system. There is no known CVE associated with this specific issue, but it falls under CWE-798: Use of Hardcoded Credentials. A realistic example would be an attacker scanning a network for open ports and then attempting to log into the web UI using default credentials; if successful, they can modify configurations or extract sensitive data.
- Root cause: The system uses insecure default credentials upon installation.
- Exploit mechanism: An attacker attempts login with default username/password combination via the web interface.
- Scope: Cisco TelePresence Conductor installations using default credentials.
3. Detection and Assessment
You can confirm if a system is vulnerable by attempting to log in with default credentials. A quick check involves accessing the web UI login page, and a thorough method would be to attempt a brute-force attack (though this should be done cautiously).
- Quick checks: Access the Cisco TelePresence Conductor web UI and observe if it prompts for credentials or allows default login.
- Scanning: Nessus plugin ID 139485 may detect this vulnerability, but results should be verified manually.
4. Solution / Remediation Steps
4.1 Preparation
- No services need to be stopped for this remediation. Roll back involves restoring the previous configuration or snapshot if needed.
4.2 Implementation
- Step 1: Log into the Cisco TelePresence Conductor web UI using the default credentials (if you haven’t already).
- Step 2: Navigate to the “System” or “Administration” section of the web interface. The exact location may vary depending on the version.
- Step 3: Locate the user account associated with administrative access.
- Step 4: Change the password for this account to a strong, unique password that meets your organization’s complexity requirements.
- Step 5: Save the changes and verify that you can no longer log in using the default credentials.

4.4 Security Practices Relevant to This Vulnerability
Several security practices can help prevent this type of issue. Least privilege reduces the impact if an account is compromised, and safe defaults ensure systems are configured securely out-of-the-box.
- Practice 1: Implement least privilege by granting users only the minimum necessary permissions to perform their tasks.
- Practice 2: Enforce strong password policies across all systems and applications.
4.5 Automation (Optional)
Automation is not recommended for this specific vulnerability due to the risk of locking yourself out if incorrectly configured.
5. Verification / Validation
- Post-fix check: Attempt to log into the Cisco TelePresence Conductor web UI using the default username and password; login should fail.
- Re-test: Repeat step 1 from section 3, which should now result in a failed login attempt.
- Monitoring: Monitor system logs for failed login attempts using default credentials as an indicator of potential attacks.
6. Preventive Measures and Monitoring
- Baselines: Update your organization’s security baseline or policy to require strong password configuration on all new systems, including Cisco TelePresence Conductor installations.
- Asset and patch process: Review configurations regularly as part of your asset management program.
7. Risks, Side Effects, and Roll Back
- Risk or side effect 1: Incorrect password configuration can lead to loss of administrative access; document the new password securely and test it thoroughly.
- Risk or side effect 2: Service interruption if the new password is lost or forgotten; ensure a recovery process is in place.
