In Gradle Enterprise before 2023.1, a remote attacker may be able to gain access to a new installation (in certain installation scenarios) because of a non-unique initial system user password. Although this password must be changed upon the first login, it is possible that an attacker logs in before the legitimate administrator logs in.
An access-control vulnerability in Gradle Enterprise 2022.4 through 2022.3.1 allows remote attackers to prevent backups from occurring, and send emails with arbitrary text content to the configured installation-administrator contact address, via HTTP access to an accidentally exposed internal endpoint. This is fixed in 2022.3.2.
Gradle Enterprise before 2022.1 allows remote code execution if the installation process did not specify an initial configuration file. The configuration allows certain anonymous access to administration and an API.
In Gradle Enterprise before 2021.4.2, the default built-in build cache configuration allowed anonymous write access. If this was not manually changed, a malicious actor with network access to the build cache could potentially populate it with manipulated entries that execute malicious code as part of a build. As of 2021.4.2, the built-in build cache is inaccessible-by-default, requiring explicit configuration of its access-control settings before it can be used. (Remote build cache nodes are unaffected as they are inaccessible-by-default.)
Gradle Enterprise before 2021.4.3 relies on cleartext data transmission in some situations. It uses Keycloak for identity management services. During the sign-in process, Keycloak sets browser cookies that effectively provide remember-me functionality. For backwards compatibility with older Safari versions, Keycloak sets a duplicate of the cookie without the Secure attribute, which allows the cookie to be sent when accessing the location that cookie is set for via HTTP. This creates the potential for an attacker (with the ability to impersonate the Gradle Enterprise host) to capture the login session of a user by having them click an http:// link to the server, despite the real server requiring HTTPS.
In Gradle Enterprise before 2021.3 (and Enterprise Build Cache Node before 10.0), there is potential cache poisoning and remote code execution when running the build cache node with its default configuration. This configuration allows anonymous access to the configuration user interface and anonymous write access to the build cache. If access control to the build cache is not changed from the default open configuration, a malicious actor with network access can populate the cache with manipulated entries that may execute malicious code as part of a build process. This applies to the build cache provided with Gradle Enterprise and the separate build cache node service if used. If access control to the user interface is not changed from the default open configuration, a malicious actor can undo build cache access control in order to populate the cache with manipulated entries that may execute malicious code as part of a build process. This does not apply to the build cache provided with Gradle Enterprise, but does apply to the separate build cache node service if used.
In Gradle Enterprise through 2021.3, probing of the server-side network environment can occur via an SMTP configuration test. The installation configuration user interface available to administrators allows testing the configured SMTP server settings. This test function can be used to identify the listening TCP ports available to the server, revealing information about the internal network environment.
An issue was discovered in Gradle Enterprise before 2021.1.2. There is potential remote code execution via the application startup configuration. The installation configuration user interface (available to administrators) allows specifying arbitrary Java Virtual Machine startup options. Some of these options, such as -XX:OnOutOfMemoryError, allow specifying a command to be run on the host. This can be abused to run arbitrary commands on the host, should an attacker gain administrative access to the application.
