CVE-2024-8805 is a high-severity vulnerability associated with BlueZ. This vulnerability allows network-adjacent attackers to execute arbitrary code on affected installations of BlueZ. Notably, authentication is not required to exploit this vulnerability, making it particularly concerning for organizations utilizing affected systems.
The specific flaw exists within the implementation of the HID over GATT Profile. The issue results from the lack of authorization prior to allowing access to functionality. An attacker can leverage this vulnerability to execute code in the context of the current user, highlighting a significant risk to organizational security.
Organizations should prioritize patching immediately to mitigate potential impacts from this vulnerability. The CVSS score for this vulnerability is 8.8, indicating a high severity level that warrants immediate attention from security teams.
As of now, there is no known public exploit available, but the potential for exploitation remains a critical threat. Organizations utilizing BlueZ should ensure that they have the latest updates installed and are monitoring for any signs of attempted exploitation.
Vulnerability Details
The vulnerability identified as CVE-2024-8805 is characterized as an Improper Access Control Remote Code Execution vulnerability in the BlueZ HID over GATT Profile. The vulnerability allows attackers to execute arbitrary code without authentication, due to the lack of authorization checks in the profile's implementation.
The CVSS score of 8.8 indicates a high severity, which reflects the potential impacts on confidentiality, integrity, and availability, all rated as high. The vulnerability affects BlueZ version 5.77 and was published on November 22, 2024.
Technical Analysis
The root cause of CVE-2024-8805 stems from the improper access control within the HID over GATT Profile implementation. The attack vector is classified as adjacent network, meaning that an attacker must be on the same local network to exploit the vulnerability.
The attack complexity for this vulnerability is low, with no privileges required for exploitation, and no user interaction needed. This significantly raises the risk profile for organizations that have devices using BlueZ.
The potential impacts include high confidentiality, integrity, and availability impacts, highlighting the critical nature of this vulnerability.
Risk & Impact Analysis
The risk to organizations includes unauthorized access to sensitive information and execution of arbitrary code, which could lead to further compromise of organizational systems. Given the nature of this vulnerability, the blast radius is considerable, as it can affect any device utilizing the vulnerable version of BlueZ.
Organizations should address this vulnerability in their priority patch cycle. With a CVSS score of 8.8, the urgency is heightened, and failure to remediate can lead to severe consequences.
