Name of the Vulnerable Software and Affected Versions: Floodlight versions 1.2 and earlier

Description: The issue is related to poor input validation in the checkFlow function within StaticFlowEntryPusherResource.java, specifically due to the mishandling of undefined fields.

Recommendations: For Floodlight versions 1.2 and earlier, as a temporary workaround, consider disabling the checkFlow function in StaticFlowEntryPusherResource.java until a patch is available.
