What is CVE-2020-15170?
CVE-2020-15170 is a high-severity missing authorization vulnerability in ctripcorp apollo, published on 10 Sep 2020. An attacker can exploit it over the internet without logging in, with no action from the victim.
Official description
apollo-adminservice before version 1.7.1 does not implement access controls. If users expose apollo-adminservice to internet(which is not recommended), there are potential security issues since apollo-adminservice is designed to work in intranet and it doesn't have access control built-in. Malicious hackers may access apollo-adminservice apis directly to access/edit the application's configurations. To fix the potential issue without upgrading, simply follow the advice that do not expose apollo-adminservice to internet.
