Published Oct 23, 2025 CVSS 4.0 · 4.8 Medium EPSS < 1% KEV · Not listed
Description
Cross-site Scripting has been identified in Moxa’s Ethernet switches, which allows an authenticated administrative attacker to inject malicious scripts to an affected device’s web service that could impact authenticated users interacting with the device’s web interface. This vulnerability is classified as stored cross-site scripting (XSS); attackers inject malicious scripts into the system, and the scripts persist across sessions. There is no impact to the confidentiality, integrity, and availability of the affected device; no loss of availability within any subsequent systems but has some loss of confidentiality and integrity within the subsequent system.
