CVE-2024-21798

Estado: AnalizadaMedia (4.8)—

ELECOM wireless LAN routers contain a cross-site scripting vulnerability. Assume that a malicious administrative user configures the affected product with specially crafted content. When another administrative user logs in and operates the product, an arbitrary script may be executed on the web browser. Note that WMC-X1800GST-B is also included in e-Mesh Starter Kit "WMC-2LX-B".
