The Loggregator Traffic Controller endpoints in cf-release v231 and lower, Pivotal Elastic Runtime versions prior to 1.5.19 AND 1.6.x versions prior to 1.6.20 are not cleansing request URL paths when they are invalid and are returning them in the 404 response. This could allow malicious scripts to be written directly into the 404 response.

The UAA OAuth approval pages in Cloud Foundry v208 to v231, Login-server v1.6 to v1.14, UAA v2.0.0 to v2.7.4.1, UAA v3.0.0 to v3.2.0, UAA-Release v2 to v7 and Pivotal Elastic Runtime 1.6.x versions prior to 1.6.20 are vulnerable to an XSS attack by specifying malicious java script content in either the OAuth scopes (SCIM groups) or SCIM group descriptions.

Cloud Foundry Garden-Linux versions prior to v0.333.0 and Elastic Runtime 1.6.x version prior to 1.6.17 contain a flaw in managing container files during Docker image preparation that could be used to delete, corrupt or overwrite host files and directories, including other container filesystems on the host.

It was discovered that cf-release v231 and lower, Pivotal Cloud Foundry Elastic Runtime 1.5.x versions prior to 1.5.17 and Pivotal Cloud Foundry Elastic Runtime 1.6.x versions prior to 1.6.18 do not properly enforce disk quotas in certain cases. An attacker could use an improper disk quota value to bypass enforcement and consume all the disk on DEAs/CELLs causing a potential denial of service for other applications.
