Severity
9.8 (Critical) - CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H
Summary
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
