OS command injection vulnerability in ELECOM wireless LAN routers allows a network-adjacent unauthenticated attacker to execute arbitrary OS commands by sending a specially crafted request to the product. Affected products and versions are as follows: WRC-X3200GST3-B v1.25 and earlier, WRC-G01-W v1.24 and earlier, and WMC-X1800GST-B v1.41 and earlier. Note that WMC-X1800GST-B is also included in e-Mesh Starter Kit "WMC-2LX-B".
The product constructs all or part of an OS command using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify the intended OS command when it is sent to a downstream component.
