CVE-2025-27558 represents a critical vulnerability in the IEEE P802.11-REVme standards, specifically affecting versions D1.1 through D7.0. This vulnerability allows FragAttacks against mesh networks that utilize Wi-Fi Protected Access (WPA, WPA2, or WPA3) or Wired Equivalent Privacy (WEP). An adversary can exploit this vulnerability to inject arbitrary frames towards devices that support receiving non-SSP A-MSDU frames.
The severity of this vulnerability is marked as critical, with a CVSS score of 9.1. This high score indicates a significant risk to organizations utilizing affected mesh networks, as it could lead to unauthorized access or control over network devices. The urgency for defenders to address this vulnerability is critical, as it can be exploited with low complexity and requires no privileges or user interaction.
The vulnerability exists due to an incorrect fix for CVE-2020-24588, and it underscores the importance of continuous monitoring and updating of network security protocols. Organizations must prioritize patching immediately to mitigate potential risks associated with this vulnerability.
As of now, the vulnerability status is awaiting analysis, but it has been confirmed that exploits are available. Organizations should remain vigilant and consult threat intelligence for the latest developments regarding this CVE.
Vulnerability Details
The official description of this vulnerability indicates that it affects IEEE P802.11-REVme D1.1 through D7.0, allowing FragAttacks against mesh networks, specifically those using WPA, WPA2, or WPA3. An attacker can inject arbitrary frames, posing a significant risk to the integrity and confidentiality of the affected systems.
The CVSS score of 9.1 categorizes this vulnerability as critical. The vulnerability type is classified under CWE-345, which refers to the improper neutralization of special elements used in an SQL command ('SQL Injection'). The potential impact includes high confidentiality and integrity loss, while availability remains unaffected.
Technical Analysis
The root cause of CVE-2025-27558 stems from an incorrect implementation related to the handling of A-MSDU frames within the P802.11 standards. The attack vector is classified as network-based, allowing attackers to leverage this vulnerability remotely without requiring physical access.
The attack complexity is low, meaning that attackers can exploit this vulnerability with minimal effort. Furthermore, no privileges are required to initiate an attack, and user interaction is not needed, making this vulnerability particularly dangerous.
In terms of impact, confidentiality and integrity are both significantly affected, with potential unauthorized access to sensitive data and manipulation of network communications. However, there is no impact on availability, as the functionality of the network remains intact.
Risk & Impact Analysis
The real-world risk of CVE-2025-27558 is significant, particularly for organizations deploying mesh networks reliant on Wi-Fi security protocols. The ability for an adversary to inject arbitrary frames can lead to severe security breaches, including data interception, manipulation, and unauthorized access to sensitive systems.
Organizations must understand that the blast radius of this vulnerability could extend beyond the initial target, potentially impacting other devices connected within the same mesh network. This interconnectedness heightens the urgency for organizations to address the vulnerability swiftly.
The urgency to patch this vulnerability is critical, given its high CVSS score and the presence of known exploits. Organizations should prioritize remediation as part of their immediate security efforts.
