## 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.

Weakness: CWE-20 (Improper Input Validation)
