Vulnerability from cvelistv5 – Published: 2025-10-23 13:56 – Updated: 2025-10-23 14:35

Summary

An acceptance of extraneous untrusted data with trusted data vulnerability has been identified in Moxa’s Ethernet switches, which allows attackers with administrative privileges to manipulate HTTP Host headers by injecting a specially crafted Host header into HTTP requests sent to an affected device’s web service. This vulnerability is classified as Host Header Injection, where invalid Host headers can manipulate to redirect users, forge links, or phishing attacks. There is no impact to the confidentiality, integrity, and availability of the affected device; no loss of confidentiality, integrity, and availability within any subsequent systems.

CVE-2025-1679 (GCVE-0-2025-1679)

Vulnerability from cvelistv5 – Published: 2025-10-23 13:51 – Updated: 2025-10-23 14:37

Summary

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.

Severity ?

4.8 (Medium)
