BBR could run arbitrary scripts on deployment VMs

Cloud Foundry BOSH Backup and Restore CLI, all versions prior to 1.5.0, does not check the authenticity of backup scripts in BOSH. A remote authenticated malicious user can modify the metadata file of a Bosh Backup and Restore job to request extra backup files from different jobs upon restore. The exploited hooks in this metadata script were only maintained in the cfcr-etcd-release, so clusters deployed with the BBR job for etcd in this release are vulnerable.

Cloud Controller provides signed URL with write authorization to read only user

Cloud Foundry Cloud Controller, versions prior to 1.78.0, contain an endpoint with improper authorization. A remote authenticated malicious user with read permissions can request package information and receive a signed bit-service url that grants the user write permissions to the bit-service.

Cloud Foundry Stratos contains a Session Collision Vulnerability

Cloud Foundry Stratos, versions prior to 2.3.0, contains an insecure session that can be spoofed. When deployed on cloud foundry with multiple instances using the default embedded SQLite database, a remote authenticated malicious user can switch sessions to another user with the same session id.

Cloud Foundry Stratos Deploys With Public Default Session Store Secret

Cloud Foundry Stratos, versions prior to 2.3.0, deploys with a public default session store secret. A malicious user with default session store secret can brute force another user's current Stratos session, and act on behalf of that user.

CredHub CLI writes environment variable credentials to disk

Cloud Foundry CredHub CLI, versions prior to 2.2.1, inadvertently writes authentication credentials provided via environment variables to its persistent config file. A local authenticated malicious user with access to the CredHub CLI config file can use these credentials to retrieve and modify credentials stored in CredHub that are authorized to the targeted user.

CF CLI does not sanitize user's password in verbose/trace/debug

Cloud Foundry CLI, versions prior to v6.43.0, improperly exposes passwords when verbose/trace/debugging is turned on. A local unauthenticated or remote authenticated malicious user with access to logs may gain part or all of a users password.

Cloud Foundry Container Runtime Leaks IAAS Credentials

Cloud Foundry Container Runtime, versions prior to 0.28.0, deploys K8s worker nodes that contains a configuration file with IAAS credentials. A malicious user with access to the k8s nodes can obtain IAAS credentials allowing the user to escalate privileges to gain access to the IAAS account.

Cloud Foundry Container Runtime allows a user to bypass security policy when talking to ETCD

Cloud Foundry Container Runtime, versions prior to 0.29.0, deploys Kubernetes clusters utilize the same CA (Certificate Authority) to sign and trust certs for ETCD as used by the Kubernetes API. This could allow a user authenticated with a cluster to request a signed certificate leveraging the Kubernetes CSR capability to obtain a credential that could escalate privilege access to ETCD.

UAA allows users to modify their own email address

Cloud Foundry UAA, versions prior to v70.0, allows a user to update their own email address. A remote authenticated user can impersonate a different user by changing their email address to that of a different user.

CAPI leaks service broker URLs and GUIDs to space developers

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.

UAA logs all query parameters with debug logging level

Cloud Foundry UAA Release, versions prior to v74.10.0, when set to logging level DEBUG, logs client_secret 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 UAA logs query parameters in tomcat access file

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.

A forged route service request using an invalid nonce can cause the gorouter to panic and crash

Cloud Foundry Routing, all versions before 0.193.0, does not properly validate nonce input. A remote unauthenticated malicious user could forge an HTTP route service request using an invalid nonce that will cause the Gorouter to crash.

Password leak in smbdriver logs

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.

UAA is vulnerable to a Blind SCIM injection leading to information disclosure

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.

Privilege Escalation via Scope Manipulation in UAA

CF UAA versions prior to 74.1.0 can request scopes for a client that shouldn't be allowed by submitting an array of requested scopes. A remote malicious user can escalate their own privileges to any scope, allowing them to take control of UAA and the resources it controls.

Privilege Escalation via Blind SCIM Injection in UAA

CF UAA versions prior to 74.1.0, allow external input to be directly queried against. A remote malicious user with 'client.write' and 'groups.update' can craft a SCIM query, which leaks information that allows an escalation of privileges, ultimately allowing the malicious user to gain control of UAA scopes they should not have.

Volume Services is vulnerable to an LDAP injection attack

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.

UAA SCIM Filter XSS

Cloud Foundry UAA, versions prior to 74.0.0, is vulnerable to an XSS attack. A remote unauthenticated malicious attacker could craft a URL that contains a SCIM filter that contains malicious JavaScript, which older browsers may execute.

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.
