CVE-2024-31948
Description
An uncaught exception flaw was found in FRRouting. This flaw allows an attacker using a malformed Prefix SID attribute in a BGP UPDATE packet to cause the bgpd daemon to crash.
Statement
The uncaught exception flaw in FRRouting's bgpd daemon, triggered by a malformed Prefix SID attribute in a BGP UPDATE packet, poses a moderate severity risk due to its potential to cause a denial of service (DoS) condition. While the vulnerability results in a crash of the bgpd daemon, leading to disruption of routing services, it primarily affects the availability aspect of the CIA triad (Confidentiality, Integrity, and Availability). Although the flaw does not directly expose sensitive information or allow unauthorized access to the system, the ability to crash a critical routing component could impact network operations and service availability. However, the exploitation requires a targeted and deliberate action by an attacker, limiting its immediate widespread impact compared to high severity vulnerabilities that could lead to data breaches or complete system compromise.
Mitigation
Mitigation for this issue is either not available or the currently available options don't meet the Red Hat Product Security criteria comprising ease of use and deployment, applicability to widespread installation base or stability.
Common Vulnerability Scoring System (CVSS) Score Details
Info alert:Important note
CVSS scores for open source components depend on vendor-specific factors (e.g. version or build chain). Therefore, Red Hat's score and impact rating can be different from NVD and other vendors. Red Hat remains the authoritative CVE Naming Authority (CNA) source for its products and services (see Red Hat classifications).
The following CVSS metrics and score provided are preliminary and subject to review.
