CVE-2020-8033

22
FAUCET Score

CVE-2020-8033 describes a Reflected Cross-Site Scripting (XSS) vulnerability in Ruckus R500 devices running firmware version 3.4.2.0.384, specifically exploitable via the "Device Name" field on the index.asp page. This medium-severity vulnerability (CVSS 6.1) can be triggered remotely with low attack complexity, requiring user interaction (e.g., clicking a malicious link) to achieve partial confidentiality and integrity impact. While no public exploit code (Metasploit, Nuclei, ExploitDB) or active exploitation (KEV) has been observed, and community discussion is minimal, organizations should still consider patching to mitigate potential risks.
