Cloudfoundry: Security Vulnerabilities
Cloud Foundry Diego, release versions prior to 2.8.0, does not properly sanitize file paths in tar and zip files headers. A remote attacker with CF admin privileges can upload a malicious buildpack that will allow a complete takeover of a Diego Cell VM and access to all apps running on that Diego Cell.

Cloud Foundry Loggregator, versions 89.x prior to 89.5 or 96.x prior to 96.1 or 99.x prior to 99.1 or 101.x prior to 101.9 or 102.x prior to 102.2, does not validate app GUID structure in requests. A remote authenticated malicious user knowing the GUID of an app may construct malicious requests to read from or write to the logs of that app.

Cloud Foundry Loggregator, versions 89.x prior to 89.5 or 96.x prior to 96.1 or 99.x prior to 99.1 or 101.x prior to 101.9 or 102.x prior to 102.2, does not handle errors thrown while constructing certain http requests. A remote authenticated user may construct malicious requests to cause the traffic controller to leave dangling TCP connections, which could cause denial of service.

Cloud Foundry routing-release, versions prior to 0.175.0, lacks sanitization for user-provided X-Forwarded-Proto headers. A remote user can set the X-Forwarded-Proto header in a request to potentially bypass an application requirement to only respond over secure connections.

Cloud Foundry Foundation UAA, versions 4.12.X and 4.13.X, introduced a feature which could allow privilege escalation across identity zones for clients performing offline validation. A zone administrator could configure their zone to issue tokens which impersonate another zone, granting up to admin privileges in the impersonated zone for clients performing offline token validation.

Cloud Foundry Garden-runC, versions prior to 1.13.0, does not correctly enforce disc quotas for Docker image layers. A remote authenticated user may push an app with a malicious Docker image that will consume more space on a Diego cell than allocated in their quota, potentially causing a DoS against the cell.

Cloud Foundry Cloud Controller, capi-release versions prior to 1.0.0 and cf-release versions prior to v237, contain a business logic flaw. An application developer may create an application with a route that conflicts with a platform service route and receive traffic intended for the service.

Applications in cf-release before 245 can be configured and pushed with a user-provided custom buildpack using a URL pointing to the buildpack. Although it is not recommended, a user can specify a credential in the URL (basic auth or OAuth) to access the buildpack through the CLI. For example, the user could include a GitHub username and password in the URL to access a private repo. Because the URL to access the buildpack is stored unencrypted, an operator with privileged access to the Cloud Controller database could view these credentials.

Cloud Foundry Cloud Controller, versions prior to 1.52.0, contains information disclosure and path traversal vulnerabilities. An authenticated malicious user can predict the location of application blobs and leverage path traversal to create a malicious application that has the ability to overwrite arbitrary files on the Cloud Controller instance.
