With Cloud Foundry Runtime cf-release versions v209 or earlier, UAA Standalone versions 2.2.6 or earlier and Pivotal Cloud Foundry Runtime 1.4.5 or earlier the change_email form in UAA is vulnerable to a CSRF attack. This allows an attacker to trigger an e-mail change for a user logged into a cloud foundry instance via a malicious link on a attacker controlled site. This vulnerability is applicable only when using the UAA internal user store for authentication. Deployments enabled for integration via SAML or LDAP are not affected.

With Cloud Foundry Runtime cf-release versions v208 or earlier, UAA Standalone versions 2.2.5 or earlier and Pivotal Cloud Foundry Runtime 1.4.5 or earlier, old Password Reset Links are not expired after the user changes their current email address to a new one. This vulnerability is applicable only when using the UAA internal user store for authentication. Deployments enabled for integration via SAML or LDAP are not affected.

A path traversal vulnerability was identified in the Cloud Foundry component Cloud Controller that affects cf-release versions prior to v208 and Pivotal Cloud Foundry Elastic Runtime versions prior to 1.4.2. Path traversal is the 'outbreak' of a given directory structure through relative file paths in the user input. It aims at accessing files and directories that are stored outside the web root folder, for disallowed reading or even executing arbitrary system commands. An attacker could use a certain parameter of the file path for instance to inject '../' sequences in order to navigate through the file system. In this particular case a remote authenticated attacker can exploit the identified vulnerability in order to upload arbitrary files to the server running a Cloud Controller instance - outside the isolated application container.

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.

With Cloud Foundry Runtime cf-release versions v209 or earlier, UAA Standalone versions 2.2.6 or earlier and Pivotal Cloud Foundry Runtime 1.4.5 or earlier the UAA logout link is susceptible to an open redirect which allows an attacker to insert malicious web page as a redirect parameter.

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.

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.

The Cloud Controller in Cloud Foundry before 239 logs user-provided service objects at creation, which allows attackers to obtain sensitive user credential information via unspecified vectors.

Pivotal Cloud Foundry 239 and earlier, UAA (aka User Account and Authentication Server) 3.4.1 and earlier, UAA release 12.2 and earlier, PCF (aka Pivotal Cloud Foundry) Elastic Runtime 1.6.x before 1.6.35, and PCF Elastic Runtime 1.7.x before 1.7.13 does not validate if a certificate is expired.
