In the MediaTek Wi-Fi driver, there is a possible undefined behavior due to incorrect error handling. This vulnerability allows local escalation of privilege with system execution privileges needed. User interaction is not needed for exploitation. The CVSS score of this vulnerability is 6.7, indicating a medium severity. Organizations should prioritize patching immediately.
Risk to organizations includes unauthorized access and potential control over affected systems, which could lead to further exploitation. As this vulnerability does not require user interaction, it poses a significant risk for devices utilizing the affected MediaTek firmware versions.
The vulnerability was published on February 6, 2023, and is currently classified as modified. Security teams should assess their environments for the presence of affected MediaTek firmware and apply patches as soon as they are available.
As of now, there are no public exploits confirmed, and the vulnerability is not listed in the Known Exploited Vulnerabilities (KEV) catalog. However, the potential impact on system integrity and availability necessitates proactive measures.
Vulnerability Details
This vulnerability is primarily categorized as a privilege escalation issue due to incorrect error handling in the MediaTek Wi-Fi driver. The vulnerability affects several firmware versions across various MediaTek products, specifically those running version 7.6.6.0.
The CVSS version 3.1 vector string for this vulnerability is CVSS:3.1/AV:L/AC:L/PR:H/UI:N/S:U/C:H/I:H/A:H, which highlights that the attack vector is local, with low complexity and high privileges required.
The vulnerability is present in various MediaTek firmware components, including mt5221, mt7603, mt7613, and others, as detailed in the CVE database.
Technical Analysis
The root cause of this vulnerability lies in the improper handling of errors within the Wi-Fi driver, leading to undefined behavior that could be exploited for privilege escalation. The attack vector is local, meaning an attacker must have physical or administrative access to the affected system.
The attack complexity is low, and the exploitation does not require user interaction, which increases the risk profile of this vulnerability. The potential impacts include high confidentiality, integrity, and availability impact, as adversaries could seize control of the system.
Risk & Impact Analysis
Real-world deployment of devices running vulnerable MediaTek firmware may expose organizations to significant risks, including unauthorized access and control of sensitive systems. Attackers may leverage this vulnerability to escalate privileges and execute arbitrary code, potentially leading to further compromise.
The blast radius of this vulnerability could extend across networks utilizing affected MediaTek products, thereby affecting multiple devices and services. Given the medium CVSS score and the absence of known exploits, organizations should address this vulnerability in their priority patch cycle.
The urgency for remediation is medium, and organizations should schedule patching as part of their regular maintenance routines to mitigate potential risks.
