Vulnerability identifier: #VU87724

Vulnerability risk: Medium

CVSSv3.1: 6.5 [CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H/E:U/RL:O/RC:C]

CVE-ID: CVE-2024-1309

CWE-ID: CWE-399

Exploitation vector: Network

Exploit availability: No

Vulnerable software:
UDP
Other software / Other software solutions

Vendor: IETF

Description

The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.

The vulnerability exists due to improper management of internal resources within the UDP implementation. An unauthenticated attacker can use maliciously-crafted packets against a UDP-based vulnerable implementation of application protocols (e.g., DNS, NTP, TFTP) that can lead to Denial-of-Service (DOS) and/or abuse of resources.

Mitigation

This vulnerability is considered as patched since there is a way to protect your systems against this time of attack.

Network providers should deploy available anti-spoofing techniques (BCP38) such as Unicast Reverse Path Forwarding (uRPF) to prevent IP spoofing in protecting their internet-facing resources against spoofing and abuse.
