Cloudfoundry : Security Vulnerabilities, CVEs, Published In 2017

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."

In Cloud Foundry capi-release versions 1.33.0 and later, prior to 1.42.0 and cf-release versions 268 and later, prior to 274, the original fix for CVE-2017-8033 introduces an API regression that allows a space developer to execute arbitrary code on the Cloud Controller VM by pushing a specially crafted application. NOTE: 274 resolves the vulnerability but has a serious bug that is fixed in 275.

In Cloud Foundry router routing-release all versions prior to v0.163.0 and cf-release all versions prior to v274, in some applications, it is possible to append a combination of characters to the URL that will allow for an open redirect. An attacker could exploit this as a phishing attack to gain access to user credentials or other sensitive data. NOTE: 274 resolves the vulnerability but has a serious bug that is fixed in 275.

In Cloud Foundry Foundation CAPI-release versions after v1.6.0 and prior to v1.38.0 and cf-release versions after v244 and prior to v270, there is an incomplete fix for CVE-2017-8035. If you took steps to remediate CVE-2017-8035 you should also upgrade to fix this CVE. A carefully crafted CAPI request from a Space Developer can allow them to gain access to files on the Cloud Controller VM for that installation, aka an Information Leak / Disclosure.

An issue was discovered in the Cloud Controller API in Cloud Foundry Foundation CAPI-release version 1.33.0 (only). The original fix for CVE-2017-8033 included in CAPI-release 1.33.0 introduces a regression that allows a space developer to execute arbitrary code on the Cloud Controller VM by pushing a specially crafted application.

An issue was discovered in the Cloud Controller API in Cloud Foundry Foundation CAPI-release versions after v1.6.0 and prior to v1.35.0 and cf-release versions after v244 and prior to v268. A carefully crafted CAPI request from a Space Developer can allow them to gain access to files on the Cloud Controller VM for that installation.

The Cloud Controller and Router in Cloud Foundry (CAPI-release capi versions prior to v1.32.0, Routing-release versions prior to v0.159.0, CF-release versions prior to v267) do not validate the issuer on JSON Web Tokens (JWTs) from UAA. With certain multi-zone UAA configurations, zone administrators are able to escalate their privileges.

An issue was discovered in the Cloud Controller API in Cloud Foundry Foundation CAPI-release versions prior to v1.35.0 and cf-release versions prior to v268. A filesystem traversal vulnerability exists in the Cloud Controller that allows a space developer to escalate privileges by pushing a specially crafted application that can write arbitrary files to the Cloud Controller VM.

In Cloud Foundry cf-release versions prior to v264; UAA release all versions of UAA v2.x.x, 3.6.x versions prior to v3.6.13, 3.9.x versions prior to v3.9.15, 3.20.x versions prior to v3.20.0, and other versions prior to v4.4.0; and UAA bosh release (uaa-release) 13.x versions prior to v13.17, 24.x versions prior to v24.12. 30.x versions prior to 30.5, and other versions prior to v41, zone administrators are allowed to escalate their privileges when mapping permissions for an external provider.

An issue was discovered in Cloud Foundry Foundation cf-release (all versions prior to v279) and UAA (30.x versions prior to 30.6, 45.x versions prior to 45.4, 52.x versions prior to 52.1). In some cases, the UAA allows an authenticated user for a particular client to revoke client tokens for other users on the same client. This occurs only if the client is using opaque tokens or JWT tokens validated using the check_token endpoint. A malicious actor could cause denial of service.

An issue was discovered in Cloud Foundry Foundation cf-release versions prior to v263; UAA release 2.x versions prior to v2.7.4.18, 3.6.x versions prior to v3.6.12, 3.9.x versions prior to v3.9.14, and other versions prior to v4.3.0; and UAA bosh release (uaa-release) 13.x versions prior to v13.16, 24.x versions prior to v24.11, 30.x versions prior to 30.4, and other versions prior to v40. There was an issue with forwarded http headers in UAA that could result in account corruption.

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.

An issue was discovered in Cloud Foundry Foundation cf-release versions prior to v260; UAA release 2.x versions prior to v2.7.4.16, 3.6.x versions prior to v3.6.10, 3.9.x versions prior to v3.9.12, and other versions prior to v3.17.0; and UAA bosh release (uaa-release) 13.x versions prior to v13.14, 24.x versions prior to v24.9, 30.x versions prior to 30.2, and other versions prior to v36. Privileged users in one zone are allowed to perform a password reset for users in a different zone.

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 Cloud Foundry Foundation cf-release versions prior to v257; UAA release 2.x versions prior to v2.7.4.14, 3.6.x versions prior to v3.6.8, 3.9.x versions prior to v3.9.10, and other versions prior to v3.15.0; and UAA bosh release (uaa-release) 13.x versions prior to v13.12, 24.x versions prior to v24.7, and other versions prior to v30. A vulnerability has been identified with the groups endpoint in UAA allowing users to elevate their privileges.

An issue was discovered in Cloud Foundry Foundation cf-release versions prior to v257; UAA release 2.x versions prior to v2.7.4.14, 3.6.x versions prior to v3.6.8, 3.9.x versions prior to v3.9.10, and other versions prior to v3.15.0; and UAA bosh release (uaa-release) 13.x versions prior to v13.12, 24.x versions prior to v24.7, and other versions prior to v30. An attacker can use a blind SQL injection attack to query the contents of the UAA database.

An issue was discovered in Cloud Foundry Foundation cf-release v255 and Staticfile buildpack versions v1.4.0 - v1.4.3. A regression introduced in the Static file build pack causes the Staticfile.auth configuration to be ignored when the Static file file is not present in the application root. Applications containing a Staticfile.auth file but not a Static file had their basic auth turned off when an operator upgraded the Static file build pack in the foundation to one of the vulnerable versions. Note that Static file applications without a Static file are technically misconfigured, and will not successfully detect unless the Static file build pack is explicitly specified.

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

Cloud Foundry Foundation BOSH Azure CPI v22 could potentially allow a maliciously crafted stemcell to execute arbitrary code on VMs created by the director, aka a "CPI code injection vulnerability."

An issue was discovered in Cloud Foundry release v247 through v252, UAA stand-alone release v3.9.0 through v3.11.0, and UAA Bosh Release v21 through v26. There is a potential to subject the UAA OAuth clients to a denial of service attack.

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.

An issue was discovered in Cloud Foundry Foundation cf-release versions prior to 250 and CAPI-release versions prior to 1.12.0. A user with the SpaceAuditor role is over-privileged with the ability to restage applications. This could cause application downtime if the restage fails.

An issue was discovered in Cloud Foundry Foundation routing-release versions prior to 0.142.0 and cf-release versions 203 to 231. Incomplete validation logic in JSON Web Token (JWT) libraries can allow unprivileged attackers to impersonate other users to the routing API, aka an "Unauthenticated JWT signing algorithm in routing" issue.

An issue was discovered in Cloud Foundry Foundation Cloud Foundry release versions prior to v245 and cf-mysql-release versions prior to v31. A command injection vulnerability was discovered in a common script used by many Cloud Foundry components. A malicious user may exploit numerous vectors to execute arbitrary commands on servers running Cloud Foundry.

SQL injection vulnerability in Pivotal Cloud Foundry (PCF) before 238; UAA 2.x before 2.7.4.4, 3.x before 3.3.0.2, and 3.4.x before 3.4.1; UAA BOSH before 11.2 and 12.x before 12.2; Elastic Runtime before 1.6.29 and 1.7.x before 1.7.7; and Ops Manager 1.7.x before 1.7.8 allows remote authenticated users to execute arbitrary SQL commands via unspecified vectors.
