Remote Command Execution via OS Command Injection in ELECOM Wireless Router WebUI

ELECOM wireless LAN routers and access points devices contain an OS Command Injection vulnerability in WebUI. If this vulnerability is exploited, an arbitrary OS command may be executed by an attacker who can log in to the product.

ELECOM wireless LAN access point devices use a hard-coded cryptographic key when creating backups of configuration files. An attacker who knows the encryption key can tamper the configuration file of the product, and a victim administrator may be tricked to use a crafted configuration file.

Cross-site scripting vulnerability exists in WRC-X3000GS2-B, WRC-X3000GS2-W, WRC-X3000GS2A-B and WRC-X3000GST2-B due to improper processing of input values in easysetup.cgi. If a user views a malicious web page while logged in to the product, an arbitrary script may be executed on the user's web browser.

WRC-X3000GS, WRC-X3000GSA, and WRC-X3000GSN contain an improper neutralization of special elements used in an OS command ('OS Command Injection') vulnerability in Connection Diagnostics page. If a remote authenticated attacker sends a specially crafted request to the affected product, an arbitrary OS command may be executed.

OS command injection vulnerability in WRC-X3000GSN v1.0.2, WRC-X3000GS v1.0.24 and earlier, and WRC-X3000GSA v1.0.24 and earlier allows a network-adjacent attacker with an administrative privilege to execute an arbitrary OS command by sending a specially crafted request to the product.

OS command injection vulnerability in WRC-X3000GS2-W v1.05 and earlier, WRC-X3000GS2-B v1.05 and earlier, and WRC-X3000GS2A-B v1.05 and earlier allows a network-adjacent authenticated user to execute an arbitrary OS command by sending a specially crafted request.
