AlienVault OTX Vulnerabilities

AlienVault OTX Malware

A flaw was found in the Open Virtual Network (OVN). In OVN clusters where BFD is used between hypervisors for high availability, an attacker can inject specially crafted BFD packets from inside unprivileged workloads, including virtual machines or containers, that can trigger a denial of service.

CVE-2024-2182 identifies a vulnerability in Open Virtual Network (OVN) version 20.03.0, specifically affecting clusters that utilize Bidirectional Forwarding Detection (BFD) between hypervisors to maintain high availability. BFD is a protocol designed to detect faults between two forwarding engines quickly. The vulnerability stems from an origin validation error that allows an attacker operating within an unprivileged workload—such as a virtual machine or container—to inject maliciously crafted BFD packets. These packets can disrupt the normal operation of BFD sessions between hypervisors, leading to a denial of service condition. This can cause network instability or outages by breaking the high availability mechanisms that rely on BFD. The flaw does not affect confidentiality or integrity but impacts availability significantly. Exploitation requires the attacker to have local privileges inside the virtualized environment but does not require user interaction. The vulnerability has a CVSS v3.1 base score of 6.5, indicating medium severity, with an attack vector of network, low attack complexity, and privileges required. No public exploits have been reported yet, but the potential for disruption in cloud and virtualized data center environments is notable. The issue highlights the importance of strict packet origin validation in network virtualization protocols and the risks posed by insufficient isolation between workloads and hypervisor communication channels.
