OS command injection vulnerability exists in awkblog v0.0.1 (commit hash:7b761b192d0e0dc3eef0f30630e00ece01c8d552) and earlier. If a remote unauthenticated attacker sends a specially crafted HTTP request, an arbitrary OS command may be executed with the privileges of the affected product on the machine running the product.
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.
