In Cloud Foundry UAA, versions prior to 74.14.0, a CSRF vulnerability exists due to the OAuth2 state parameter not being checked in the callback function when authenticating with external identity providers.

Cloud Foundry Cloud Controller (CAPI), versions prior to 1.91.0, logs properties of background jobs when they are run, which may include sensitive information such as credentials if provided to the job. A malicious user with access to those logs may gain unauthorized access to resources protected by such credentials.

Inappropriate user token revocation due to a logic error in the token revocation endpoint implementation in Cloudfoundry UAA v77.30.0 to v78.7.0 and in Cloudfoundry Deployment v48.7.0 to v54.10.0.

Route Services can be leveraged to send app traffic to network destinations outside of an app's configured egress rules. As a result, a malicious developer with access to Cloudfoundry could configure a route-service that would allow it to send requests to HTTP services on internal networks reachable by the Gorouter, which may not have previously had direct access from outside networks, or from the application. Routing release: affected from v0.118.0 through v0.371.0 (inclusive); upgrade to v0.372.0 or greater. CF Deployment: affected from v0.0.2 through v54.14.0 (inclusive); upgrade to v55.0.0 or greater (includes routingrelease v0.372.0).

A flaw was found Go's net/http package. Servers using ReverseProxy from net/http in the Go standard library are vulnerable to a data race that results in a denial of service. The highest threat from this vulnerability is to system availability.

Cloud Foundry UAA release versions from v77.21.0 to v7.31.0 are vulnerable to a private key exposure in logs.

Starting with diego-release 2.55.0 and up to 2.69.0, and starting with CF Deployment 17.1 and up to 23.2.0, apps are accessible via another port on diego cells, allowing application ingress without a client certificate. If mTLS route integrity is enabled AND unproxied ports are turned off, then an attacker could connect to an application that should be only reachable via mTLS, without presenting a client certificate.

Cloud foundry instances having CAPI version between 1.140 and 1.152.0 along with loggregator-agent v7+ may override other users syslog drain credentials if they're aware of the client certificate used for that syslog drain. This applies even if the drain has zero certs. This would allow the user to override the private key and add or modify a certificate authority used for the connection.

In Cloud foundry routing release versions from 0.262.0 and prior to 0.266.0,a bug in the gorouter process can lead to a denial of service of applications hosted on Cloud Foundry. Under the right circumstances, when client connections are closed prematurely, gorouter marks the currently selected backend as failed and removes it from the routing pool.

Cloud Foundry cf-deployment, versions prior to 7.9.0, contain java components that are using an insecure protocol to fetch dependencies when building. A remote unauthenticated malicious attacker could hijack the DNS entry for the dependency, and inject malicious code into the component.

Cloud Foundry Garden-runC, versions prior to 1.11.0, contains an information exposure vulnerability. A user with access to Garden logs may be able to obtain leaked credentials and perform authenticated actions using those credentials.

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.

CAPI (Cloud Controller) versions prior to 1.101.0 are vulnerable to a denial-of-service attack in which an unauthenticated malicious attacker can send specially-crafted YAML files to certain endpoints, causing the YAML parser to consume excessive CPU and RAM.

Cloud Foundry Cloud Controller API (CAPI), version 1.88.0, allows space developers to list all global service brokers, including service broker URLs and GUIDs, which should only be accessible to admins.

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 Routing (Gorouter) versions prior to 0.206.0 allow a malicious developer with "cf push" access to cause denial-of-service to the CF cluster by pushing an app that returns specially crafted HTTP responses that crash the Gorouters.

Cloud Foundry SMB Volume, versions prior to v2.0.3, accidentally outputs sensitive information to the logs. A remote user with access to the SMB Volume logs can discover the username and password for volumes that have been recently created, allowing the user to take control of the SMB Volume.

In cf-deployment before 1.14.0 and routing-release before 0.172.0, the Cloud Foundry Gorouter mishandles WebSocket requests for AWS Application Load Balancers (ALBs) and some other HTTP-aware Load Balancers. A user with developer privileges could use this vulnerability to steal data or cause denial of service.

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 CAPI (Cloud Controller) versions prior to 1.98.0 allow authenticated users having only the "cloudcontroller.read" scope, but no roles in any spaces, to list all droplets in all spaces (whereas they should see none).

Cloud Foundry UAA, versions prior to v74.3.0, contains an endpoint that is vulnerable to SCIM injection attack. A remote authenticated malicious user with scim.invite scope can craft a request with malicious content which can leak information about users of the UAA.

Cloud Foundry Routing, all versions before 0.0.0-20191101214924-b1b5c44e050f, does not properly validate nonce input. A remote unauthorized malicious user could forge a route service request using an invalid nonce that will cause the Gorouter to crash.

Cloud Foundry UAA Release, versions prior to v74.8.0, logs all query parameters to tomcat’s access file. If the query parameters are used to provide authentication, ie. credentials, then they will be logged as well.

In Cloud Controller versions prior to 1.46.0, cf-deployment versions prior to 1.3.0, and cf-release versions prior to 283, Cloud Controller accepts refresh tokens for authentication where access tokens are expected. This exposes a vulnerability where a refresh token that would otherwise be insufficient to obtain an access token, either due to lack of client credentials or revocation, would allow authentication.

Cloud Foundry NFS Volume Service, 1.7.x versions prior to 1.7.11 and 2.x versions prior to 2.3.0, is vulnerable to LDAP injection. A remote authenticated malicious space developer can potentially inject LDAP filters via service instance creation, facilitating the malicious space developer to deny service or perform a dictionary attack.

Cloud Foundry UAA Release, versions prior to v74.10.0, when set to logging level DEBUG, logs clientsecret credentials when sent as a query parameter. A remote authenticated malicious user could gain access to user credentials via the uaa.log file if authentication is provided via query parameters.

Cloud Foundry CAPI (Cloud Controller), versions prior to 1.97.0, when used in a deployment where an app domain is also the system domain (which is true in the default CF Deployment manifest), were vulnerable to developers maliciously or accidentally claiming certain sensitive routes, potentially resulting in the developer's app handling some requests that were expected to go to certain system components.

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 Routing (Gorouter), versions prior to 0.204.0, when used in a deployment with NGINX reverse proxies in front of the Gorouters, is potentially vulnerable to denial-of-service attacks in which an unauthenticated malicious attacker can send specially-crafted HTTP requests that may cause the Gorouters to be dropped from the NGINX backend pool.

An issue was discovered in Cloud Foundry Foundation capi-release (all versions prior to 1.45.0), cf-release (all versions prior to v280), and cf-deployment (all versions prior to v1.0.0). The Cloud Controller does not prevent space developers from creating subdomains to an already existing route that belongs to a different user in a different org and space, aka an "Application Subdomain Takeover."
