CVE-2020-26879 Scanner

Ruckus vRioT is a network management tool largely used by organizations to manage connected IoT devices. It enables administrators to monitor device health and performance through a centralized interface. Companies rely on Ruckus vRioT to ensure seamless operations and secure IoT deployments. Highlighting its wide usage, this software offers API functionalities to integrate smoothly with other management tools. Service providers and enterprises depend on Ruckus vRioT for efficient device management and security assurance. Automated processes facilitated by the software are crucial for maintaining operational efficacy in IoT environments.

The vulnerability in Ruckus vRioT relates to an unauthorized admin access issue, which allows attackers to bypass authentication controls. This is due to a hardcoded token embedded in the software which grants unauthorized users access to sensitive configurations. Such vulnerabilities pose significant risks by potentially exposing administrative functions to unauthorized entities. Local exploitation does not require elevated privileges, making it a concerning security flaw. By leveraging this flaw, cybercriminals can execute operations that are normally restricted to authorized personnel. Addressing this vulnerability is vital to safeguarding networks from unauthorized modifications.

Technically, the vulnerability arises from a fixed authentication token present in validate_token.py within the software. Attackers can utilize this token to interact with Ruckus' API without undergoing legitimate authentication processes. The vulnerability affects endpoints such as /service/v1/createUser where attackers can create new users with administrative rights. Security mechanisms intended to confirm user identity are effectively bypassed, resulting in potential unauthorized access. Necessary precautions include monitoring API activity and updating software to ensure tokens cannot be misused. Misuse of this flaw can lead to data breaches and loss of administrative control.

Potential effects of exploiting this vulnerability include unauthorized data access, administrative control, and configuration changes. Attackers can alter settings, create or modify user accounts, and potentially disrupt network operations. There is also a risk of data theft, as illegitimate administrative access can result in sensitive information being compromised. Malicious actors may install backdoors, granting them prolonged access to the system. Ultimately, exploitation of this vulnerability deteriorates network integrity and compromises device security and confidentiality. Organizations must prioritize remedial measures to prevent exploitation.
