IllusionCloud Warns of New DDoS Amplification Vector Using SLP Protocol

Protecting Your Network Security

DDoS Amplification Vector

A new DDoS amplification vector that leverages the Service Location Protocol (SLP) has been discovered. Researchers Pedro Umbelino at Bitsight and Marco Lux at Curesec have identified this attack vector as CVE-2023-29552, which has an amplification factor of up to 2,200x. This amplification factor makes it the third-largest amplification factor discovered to date, which is a significant concern for network operators and cybersecurity professionals.

SLP is an obsolete protocol designed to enable devices on a local area network to interact with each other without prior knowledge. However, many commercial products still support it, which means that it is still widely used. Since SLP has no method for authentication, it should never be exposed to the public Internet. Unfortunately, upwards of 35,000 Internet endpoints have their devices’ SLP service exposed and accessible to anyone. This vulnerability allows malicious actors to take advantage of the amplification vector and launch DDoS attacks against vulnerable targets.

Therefore, network operators should consider blocking UDP port 427 via access control lists or other means. This port is rarely used on the public Internet, which means that it is relatively safe to block without impacting legitimate traffic. Blocking this port can help mitigate the risk of SLP-based DDoS attacks and keep your network secure.
