Red Hat Jboss Web Server 7
Monthly
The AdvertiseListenerImpl component in mod_cluster's core multicast UDP handler can be permanently crashed by a single crafted datagram, affecting Red Hat JBoss Enterprise Application Platform 7 and 8, JBoss Web Server 5 through 7, and Red Hat Single Sign-On 7. An unauthenticated attacker with adjacency to the mod_cluster multicast group can silently terminate the advertise listener thread, causing the affected node to stop receiving cluster topology updates until manually restarted - with no runtime indication of failure since isListening() continues returning true. No public exploit is identified at time of analysis, and this CVE is not listed in the CISA KEV catalog based on available data.
