An issue was discovered in Pivotal PCF Elastic Runtime 1.6.x versions prior to 1.6.60, 1.7.x versions prior to 1.7.41, 1.8.x versions prior to 1.8.23, and 1.9.x versions prior to 1.9.1. Incomplete validation logic in JSON Web Token (JWT) libraries can allow unprivileged attackers to impersonate other users in multiple components included in PCF Elastic Runtime, aka an "Unauthenticated JWT signing algorithm in multiple components" issue.

An issue was discovered in Cloud Foundry Foundation cf-release versions prior to v258; UAA release 2.x versions prior to v2.7.4.15, 3.6.x versions prior to v3.6.9, 3.9.x versions prior to v3.9.11, and other versions prior to v3.16.0; and UAA bosh release (uaa-release) 13.x versions prior to v13.13, 24.x versions prior to v24.8, and other versions prior to v30.1. An authorized user can use a blind SQL injection attack to query the contents of the UAA database, aka "Blind SQL Injection with privileged UAA endpoints."

An issue was discovered in Pivotal PCF Elastic Runtime 1.6.x versions prior to 1.6.65, 1.7.x versions prior to 1.7.48, 1.8.x versions prior to 1.8.28, and 1.9.x versions prior to 1.9.5. Several credentials were present in the logs for the Notifications errand in the PCF Elastic Runtime tile.

An issue was discovered in Cloud Foundry Foundation cf-release versions prior to v261; UAA release 2.x versions prior to v2.7.4.17, 3.6.x versions prior to v3.6.11, 3.9.x versions prior to v3.9.13, and other versions prior to v4.2.0; and UAA bosh release (uaa-release) 13.x versions prior to v13.15, 24.x versions prior to v24.10, 30.x versions prior to 30.3, and other versions prior to v37. There is privilege escalation (arbitrary password reset) with user invitations.

The UAA reset password flow in Cloud Foundry release v236 and earlier versions, UAA release v3.3.0 and earlier versions, all versions of Login-server, UAA release v10 and earlier versions and Pivotal Elastic Runtime versions prior to 1.7.2 is vulnerable to a brute force attack due to multiple active codes at a given time. 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 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.
