New SLP Vulnerability Could Let Attackers Launch 2200x Powerful DDoS Attacks

Details have emerged about a high-severity security vulnerability impacting Service Location Protocol SLP that could be weaponized to launch volumetric denial-of-service attacks against targets. "Attackers exploiting this vulnerability could leverage vulnerable instances to launch massive...

Abuse of the Service Location Protocol May Lead to DoS Attacks

The Service Location Protocol SLP, RFC 2608link is external allows an unauthenticated remote attacker to register arbitrary services. This could allow an attacker to use spoofed UDP traffic to conduct a denial-of-service DoS attack with a significant amplification factor. Researchers from Bitsigh...
