Command injection vulnerability in Movistar 4G router affecting version ES_WLD71-T1_v2.0.201820. This vulnerability allows an authenticated user to execute commands inside the router by making a POST request to the URL '/cgi-bin/gui.cgi'.
Solution:
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.
