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.

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.
