Vulnerabilities

An issue was discovered in OpenDaylight Authentication, Authorization and Accounting (AAA) through 0.19.3. A rogue controller can join a cluster to impersonate an offline peer, even if this rogue controller does not possess the complete cluster configuration information.

In OpenDaylight Model-Driven Service Abstraction Layer (MD-SAL) through 13.0.1, a controller with a follower role can configure flow entries in an OpenDaylight clustering deployment.

A flaw was found in Opendaylight's SDNInterfaceapp (SDNI). Attackers can SQL inject the component's database (SQLite) without authenticating to the controller or SDNInterfaceapp. SDNInterface has been deprecated in OpenDayLight since it was last used in the final Carbon series release. In addition to the component not being included in OpenDayLight in newer releases, the SDNInterface component is not packaged in the opendaylight package included in RHEL.

OpenDayLight version Carbon SR3 and earlier contain a vulnerability during node reconciliation that can result in traffic flows that should be expired or should expire shortly being re-installed and their timers reset resulting in traffic being allowed that should be expired.

OpenFlow Plugin and OpenDayLight Controller versions Nitrogen, Carbon, Boron, Robert Varga, Anil Vishnoi contain a flaw when multiple 'expired' flows take up the memory resource of CONFIG DATASTORE which leads to CONTROLLER shutdown. If multiple different flows with 'idle-timeout' and 'hard-timeout' are sent to the Openflow Plugin REST API, the expired flows will eventually crash the controller once its resource allocations set with the JVM size are exceeded. Although the installed flows (with timeout set) are removed from network (and thus also from controller's operations DS), the expired entries are still present in CONFIG DS. The attack can originate both from NORTH or SOUTH. The above description is for a north bound attack. A south bound attack can originate when an attacker attempts a flow flooding attack and since flows come with timeouts, the attack is not successful. However, the attacker will now be successful in CONTROLLER overflow attack (resource consumption). Although, the network (actual flow tables) and operational DS are only (~)1% occupied, the controller requests for resource consumption. This happens because the installed flows get removed from the network upon timeout.

OpenDaylight Karaf 0.6.1-Carbon fails to clear the cache after a password change, allowing the old password to be used until the Karaf cache is manually cleared (e.g. via restart).

DOMRpcImplementationNotAvailableException when sending Port-Status packets to OpenDaylight. Controller launches exceptions and consumes more CPU resources. Component: OpenDaylight is vulnerable to this flaw. Version: The tested versions are OpenDaylight 3.3 and 4.0.
