An issue was discovered in SageMath Sage Cell Server through 2019-10-05. Python Code Injection can occur in the context of an internet facing web application. Malicious actors can execute arbitrary commands on the underlying operating system, as demonstrated by an __import__('os').popen('whoami').read() line. NOTE: the vendor's position is that the product is "vulnerable by design" and the current behavior will be retained
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.
