CVE-2024-8110 in Dual-redundant Platform for Computer PC2CKM
Summary
by MITRE • 09/17/2024
Denial of Service (DoS) vulnerability has been found in Dual-redundant Platform for Computer. If a computer on which the affected product is installed receives a large number of UDP broadcast packets in a short period, occasionally that computer may restart. If both the active and standby computers are restarted at the same time, the functionality on that computer may be temporarily unavailable.

The CVE-2024-8110 vulnerability represents a critical denial of service weakness in dual-redundant platform systems designed for high availability and fault tolerance. This vulnerability specifically targets the network packet handling mechanisms of these redundant systems, where two computers operate in active-standby configuration to ensure continuous operation. The flaw manifests when the system receives an excessive volume of UDP broadcast packets within a brief timeframe, triggering unexpected system restarts that can compromise the entire platform's availability.
The technical implementation of this vulnerability exploits the insufficient packet filtering and rate limiting mechanisms within the dual-redundant platform's network stack. When subjected to a flood of UDP broadcast traffic, the system's processing capabilities become overwhelmed, causing the operating system to initiate automatic restart procedures as a protective measure against what it perceives as a system overload condition. This behavior is particularly concerning because the vulnerability affects both active and standby systems simultaneously, creating a cascading failure scenario that eliminates the redundancy benefits these platforms are specifically designed to provide.
From an operational impact perspective, this vulnerability directly violates the fundamental principles of high availability architecture and can result in complete system unavailability during the restart sequence. The simultaneous restart of both active and standby systems creates a window of vulnerability where the platform cannot serve its intended function, potentially leading to extended downtime that could affect critical operations. The timing of these restarts is particularly problematic as they occur during periods of high network activity, making it difficult to predict or prevent the service interruption.
The vulnerability aligns with CWE-400, which addresses "Uncontrolled Resource Consumption," and demonstrates characteristics consistent with the ATT&CK technique T1499.004 for "Endpoint Denial of Service." Organizations utilizing dual-redundant platforms must implement immediate mitigations including network-level rate limiting, UDP broadcast packet filtering, and enhanced monitoring of network traffic patterns. The recommended defensive measures should include configuring firewalls to limit broadcast traffic volumes, implementing intrusion detection systems to identify abnormal packet patterns, and establishing automated alerting mechanisms to detect potential exploitation attempts. Additionally, system administrators should consider implementing redundant network paths and load balancing solutions to prevent single points of failure while ensuring that the platform maintains its intended availability characteristics despite the vulnerability.
