KL-001-2021-004: CommScope Ruckus IoT Controller Hard-coded Web Application Administrator Password Title: CommScope Ruckus IoT Controller Hard-coded Web Application Administrator Password Advisory ID: KL-001-2021-004 Publication Date: 2021.05.26 Publication URL: https://korelogic.com/Resources/Advisories/KL-001-2021-004.txt 1. Vulnerability Details Affected Vendor: CommScope Affected Product: Ruckus IoT Controller Affected Version: 1.7.1.0 and earlier Platform: Linux CWE Classification: CWE-259: Use of Hard-coded Password CVE ID: CVE-2021-33219 2. Vulnerability Description An undocumented, administrative-level, hard coded web application account exists in the IoT Controller OVA which cannot be changed by the customer. 3. Technical Description Ruckus vRIoT server software is available from the software library at: https://support.ruckuswireless.com/software/ Once the OVA is imported into VirtualBox, a VMDK file is created. The VMDK file can be mounted and the directory structure and its contents can be perused. The virtual appliance contains two web application accounts with passwords stored in clear text on the file system. The two accounts are 'admin' and 'nplus1user'. The 'admin' account is documented in vendor documentation, but the 'nplus1user' account is undocumented. The password for 'admin' is documented and can be changed by the user. The password for the 'nplus1user' account is 'nplus1user'. Both accounts are administrative-level accounts. The virtual appliance does not appear to offer a mechanism for changing the default password from the vendor for the 'nplus1user' account. 4. Mitigation and Remediation Recommendation The vendor has released an updated firmware (1.8.0.0) which remediates the described vulnerability. Firmware and release notes are available at: https://www.commscope.com/globalassets/digizuite/917216-faq-security-advisory-id-20210525-v1-0.pdf 5.
