CVE-2023-7338 — Ruckus Unleashed Authenticated RCE in Gateway Mode

Ruckus Unleashed contains a remote code execution vulnerability in the web-based management interface that allows authenticated remote attackers to execute arbitrary code on the system when gateway mode is enabled. Attackers can exploit this vulnerability by sending specially crafted requests through the management interface to achieve arbitrary code execution on affected systems.

Low

Who exploits it and how urgent it is

A 0–100 score combining confirmed exploitation, ransomware and APT use, public exploits, EPSS and severity.

No exploitation signal in the sources consulted so far.

How the score was calculated

EPSS 0.5% (30-day exploitation probability)+6
Technical severity (high)+6

The score orders the patch queue; it does not replace your asset context (internet exposure, criticality, compensating controls).

Triage

Is it exploited, how likely is exploitation, what does it touch, and how severe do the sources call it.

Remediation

Fixes and mitigations documented by the sources — linked to the original advisory.

No fix documented by the sources we poll. That does not mean none exists: check the vendor advisory.

First 24 hours

Ordered from the record’s own fields — exposure first, because you cannot patch what you have not found. A rule-generated starting point.

Identify exposed assets running the affected vendor/product/version combinations (Ruckus Networks Ruckus C110, Ruckus Networks Ruckus E510, Ruckus Networks Ruckus H320…).
No fix documented in the sources: reduce exposure and monitor the vendor advisory.
Search available logs for exploit probes matching the vulnerability class (injection), errors and authentication anomalies.

What should defenders know first?

CVE-2023-7338 is "Ruckus Unleashed Authenticated RCE in Gateway Mode", rated High. It affects Ruckus C110 (Ruckus Networks); versions are in the scope table. It is not in CISA KEV, which does not rule out exploitation. CVSS 7.5 describes technical severity. EPSS 0.52% estimates the probability of exploitation in 30 days; neither replaces your asset context. First verify whether exposed or business-critical assets run the affected versions, apply vendor fixes or mitigations, and preserve logs for review.
