The Netconf (TCP) service in OpenDaylight 1.0 allows remote attackers to read arbitrary files via an XML external entity declaration in conjunction with an entity reference in an XML-RPC message, related to an XML External Entity (XXE) issue.

OpenDaylight defense4all 1.1.0 and earlier allows remote authenticated users to write report data to arbitrary files.

hosttracker in OpenDaylight l2switch allows remote attackers to change the host location information by spoofing the MAC address, aka "topology spoofing."

OpenFlow plugin for OpenDaylight before Helium SR3 allows remote attackers to spoof the SDN topology and affect the flow of data, related to "fake LLDP injection."

OpenFlow plugin for OpenDaylight before Helium SR3 allows remote attackers to spoof the SDN topology and affect the flow of data, related to the reuse of LLDP packets, aka "LLDP Relay."

The custom authentication realm used by karaf-tomcat's "opendaylight" realm in Opendaylight before Helium SR3 will authenticate any username and password combination.

Denial of Service attack when the switch rejects to receive packets from the controller. Component: This vulnerability affects OpenDaylight odl-l2switch-switch, which is the feature responsible for the OpenFlow communication. Version: OpenDaylight versions 3.3 (Lithium-SR3), 3.4 (Lithium-SR4), 4.0 (Beryllium), 4.1 (Beryllium-SR1), 4.2 (Beryllium-SR2), and 4.4 (Beryllium-SR4) are affected by this flaw. Java version is openjdk version 1.8.0_91.

Controller throws an exception and does not allow user to add subsequent flow for a particular switch. Component: OpenDaylight odl-restconf feature contains this flaw. Version: OpenDaylight 4.0 is affected by this flaw.

Java out of memory error and significant increase in resource consumption. Component: OpenDaylight odl-mdsal-xsql is vulnerable to this flaw. Version: The tested versions are OpenDaylight 3.3 and 4.0.

StreamCorruptedException and NullPointerException in OpenDaylight odl-mdsal-xsql. Controller launches exceptions in the console. Component: OpenDaylight odl-mdsal-xsql is vulnerable to this flaw. Version: The tested versions are OpenDaylight 3.3 and 4.0.

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.

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).

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 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.

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.

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.
