CVE-2022-39064 is a high-severity vulnerability impacting the IKEA TRÅDFRI bulb firmware. This vulnerability allows an attacker to disrupt the operation of the bulb by sending a malformed IEEE 802.15.4 (Zigbee) frame. When a single malformed frame is sent, the bulb blinks, and if the same frame is resent multiple times, it triggers a factory reset. This factory reset results in the bulb losing its configuration information, including the Zigbee network details and current brightness levels.
After this attack, all lights connected to the affected bulb turn on at full brightness, rendering them uncontrollable via the IKEA Home Smart app or the TRÅDFRI remote control. The nature of the malformed Zigbee frame as an unauthenticated broadcast message means that all vulnerable devices within radio range are susceptible to this attack.
The CVSS 3.1 Base Score for this vulnerability is 8.1, indicating its high severity. Organizations operating these smart lighting systems need to be aware of the implications of this vulnerability, as it poses a significant risk to operational security and user experience.
Given the potential impact, organizations should prioritize patching immediately to prevent unauthorized access and operational disruption.
Vulnerability Details
The vulnerability is classified under CWE-241, which relates to improper handling of unexpected input. The affected product is identified as the TRÅDFRI LED1732G11 firmware by IKEA, with the vulnerability being published on October 14, 2022. Its potential for exploitation and the lack of required privileges (none) further emphasize the need for immediate remediation.
Technical Analysis
The root cause of CVE-2022-39064 lies in the lack of validation for incoming Zigbee frames. An attacker can exploit this vulnerability by leveraging the adjacent network attack vector, which requires minimal complexity and no user interaction. The integrity and availability impacts are both classified as high, further underscoring the criticality of this vulnerability.
Organizations that deploy these smart lighting solutions must ensure that they monitor for any anomalous behavior indicative of exploitation attempts. Given the straightforward nature of this attack, it is crucial to implement network controls to mitigate the risks associated with unauthorized frame transmission.
Risk & Impact Analysis
The real-world deployment risk associated with CVE-2022-39064 is substantial. An attacker exploiting this vulnerability can disrupt normal operations, leading to potential safety hazards due to unregulated lighting. The urgency for organizations to address this vulnerability is high due to its CVSS score of 8.1, which indicates a critical need for timely remediation.
Organizations should assess the blast radius of this vulnerability, particularly for environments heavily relying on smart lighting for operational purposes. The potential for multiple devices to be affected simultaneously increases the urgency for immediate action.
