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.

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 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.

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.

The Cloud Controller in Cloud Foundry cf-release versions prior to v255 allows authenticated developer users to exceed memory and disk quotas for tasks.

An issue was discovered in Cloud Foundry Foundation cf-release versions prior to v250 and CAPI-release versions prior to v1.12.0. Cloud Foundry logs the credentials returned from service brokers in Cloud Controller system component logs. These logs are written to disk and often sent to a log aggregator via syslog.
