webcheckout in myrepos through 1.20171231 does not sanitize URLs that are passed to git clone, allowing a malicious website operator or a MitM attacker to take advantage of it for arbitrary code execution, as demonstrated by an ext::sh -c attack or an option injection attack.
The product constructs all or part of a command, data structure, or record using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify how it is parsed or interpreted when it is sent to a downstream component.
