Cloudfoundry Cf release 184

Applications deployed to Cloud Foundry, versions v166 through v227, may be vulnerable to a remote disclosure of information, including, but not limited to environment variables and bound service details. For applications to be vulnerable, they must have been staged using automatic buildpack detection, passed through the Java Buildpack detection script, and allow the serving of static content from within the deployed artifact. The default Apache Tomcat configuration in the affected java buildpack versions for some basic web application archive (WAR) packaged applications are vulnerable to this issue.

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.

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.

An issue was discovered in these Pivotal Cloud Foundry products: all versions prior to cf-release v270, UAA v3.x prior to v3.20.2, and UAA bosh v30.x versions prior to v30.8 and all other versions prior to v45.0. A cross-site scripting (XSS) attack is possible in the clientId parameter of a request to the UAA OpenID Connect check session iframe endpoint used for single logout session management.

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."

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.

Cloud Foundry Runtime cf-release before 216, UAA before 2.5.2, and Pivotal Cloud Foundry (PCF) Elastic Runtime before 1.7.0 allow attackers to have unspecified impact via vectors involving emails with password recovery links, aka "Cross Domain Referer Leakage."

Cloud Foundry Runtime cf-release before 216, UAA before 2.5.2, and Pivotal Cloud Foundry (PCF) Elastic Runtime before 1.7.0 allow attackers to have unspecified impact by leveraging failure to expire password reset links.

The password change functionality in Cloud Foundry Runtime cf-release before 216, UAA before 2.5.2, and Pivotal Cloud Foundry (PCF) Elastic Runtime before 1.7.0 allow attackers to have unspecified impact by leveraging failure to expire existing sessions.

Cloud Foundry Runtime cf-release before 216, UAA before 2.5.2, and Pivotal Cloud Foundry (PCF) Elastic Runtime before 1.7.0 allow remote attackers to conduct cross-site request forgery (CSRF) attacks on PWS and log a user into an arbitrary account by leveraging lack of CSRF checks.

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.

The identity zones feature in Pivotal Cloud Foundry 208 through 229; UAA 2.0.0 through 2.7.3 and 3.0.0; UAA-Release 2 through 4, when configured with multiple identity zones; and Elastic Runtime 1.6.0 through 1.6.13 allows remote authenticated users with privileges in one zone to gain privileges and perform operations on a different zone via unspecified vectors.

Gorouter in Cloud Foundry cf-release v141 through v228 allows man-in-the-middle attackers to conduct cross-site scripting (XSS) attacks via vectors related to modified requests.

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.

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.

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 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 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 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.

The Loggregator Traffic Controller endpoints in cf-release v231 and lower, Pivotal Elastic Runtime versions prior to 1.5.19 AND 1.6.x versions prior to 1.6.20 are not cleansing request URL paths when they are invalid and are returning them in the 404 response. This could allow malicious scripts to be written directly into the 404 response.

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.
