Description

Brant Knudson discovered that OpenStack Keystone did not properly perform input sanitization when performing endpoint catalog substitution. A remote attacker with privileged access for creating endpoints could exploit this to obtain sensitive information.

Note that Tenable Network Security has extracted the preceding description block directly from the Ubuntu security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.
