When an Apache Geode server versions 1.0.0 to 1.8.0 is operating in secure mode, a user with write permissions for specific data regions can modify internal cluster metadata. A malicious user could modify this data in a way that affects the operation of the cluster.

When an Apache Geode server versions 1.0.0 to 1.4.0 is configured with a security manager, a user with DATA:WRITE privileges is allowed to deploy code by invoking an internal Geode function. This allows remote code execution. Code deployment should be restricted to users with DATA:MANAGE privilege.

In Apache Geode before v1.4.0, the Geode server stores application objects in serialized form. Certain cluster operations and API invocations cause these objects to be deserialized. A user with DATA:WRITE access to the cluster may be able to cause remote code execution if certain classes are present on the classpath.

In Apache Geode before v1.4.0, the TcpServer within the Geode locator opens a network port that deserializes data. If an unprivileged user gains access to the Geode locator, they may be able to cause remote code execution if certain classes are present on the classpath.

When an Apache Geode cluster before v1.4.0 is operating in secure mode, the Geode configuration service does not properly authorize configuration requests. This allows an unprivileged user who gains access to the Geode locator to extract configuration data and previously deployed application code.

When an Apache Geode cluster before v1.3.0 is operating in secure mode, a user with read access to specific regions within a Geode cluster may execute OQL queries containing a region name as a bind parameter that allow read access to objects within unauthorized regions.

When an Apache Geode cluster before v1.3.0 is operating in secure mode, a user with read access to specific regions within a Geode cluster may execute OQL queries that allow read and write access to objects within unauthorized regions. In addition a user could invoke methods that allow remote code execution.

When an Apache Geode cluster before v1.3.0 is operating in secure mode and an authenticated user connects to a Geode cluster using the gfsh tool with HTTP, the user is able to obtain status information and control cluster members even without CLUSTER:MANAGE privileges.

When an Apache Geode cluster before v1.2.1 is operating in secure mode, an unauthenticated client can enter multi-user authentication mode and send metadata messages. These metadata operations could leak information about application data types. In addition, an attacker could perform a denial of service attack on the cluster.

When a cluster is operating in secure mode, a user with read privileges for specific data regions can use the gfsh command line utility to execute queries. In Apache Geode before 1.2.1, the query results may contain data from another user's concurrently executing gfsh query, potentially revealing data that the user is not authorized to view.
