CVE-2025-69822 identifies a security vulnerability in the Atomberg Erica Smart Fan firmware version V1.0.36. The flaw arises from improper handling of deauthentication frames within the device's wireless communication stack. An attacker can craft and send malicious deauth frames to the fan, which triggers unintended behavior allowing the attacker to extract sensitive information stored or processed by the device. Additionally, this crafted frame can be leveraged to escalate privileges, potentially granting the attacker administrative control over the fan’s firmware and settings. The vulnerability exploits weaknesses in the Wi-Fi protocol implementation, specifically the lack of robust validation or authentication of deauth frames, which are typically used to disconnect clients from wireless access points. Although no exploits have been reported in the wild and no patches have been released, the flaw represents a significant risk due to the potential for unauthorized access and control. The affected firmware version is V1.0.36, but no further version details or affected hardware variants are specified. The vulnerability impacts confidentiality by exposing sensitive data and integrity by allowing unauthorized changes to device operation. The attack does not require prior authentication, increasing its risk profile. The absence of a CVSS score necessitates an expert severity assessment based on the described impact and attack vector.

For European organizations, the vulnerability could lead to unauthorized access to smart fan devices deployed in residential, commercial, or office environments. This could result in privacy violations if sensitive data such as network credentials or user settings are exposed. Privilege escalation could allow attackers to manipulate device behavior, potentially causing denial of service or using the compromised device as a foothold for lateral movement within local networks. In environments with many IoT devices, such as smart offices or smart homes, this could degrade trust in IoT security and increase operational risks. Although the direct impact on critical infrastructure is limited, the vulnerability could be exploited as part of broader attacks targeting IoT ecosystems. The lack of patches and known exploits means organizations must proactively mitigate risk. The impact is particularly relevant for sectors with high IoT adoption, including technology firms, smart building operators, and residential property managers in Europe.

1. Immediate mitigation involves isolating affected Atomberg Erica Smart Fans on segmented networks to limit exposure to wireless attacks. 2. Deploy wireless intrusion detection/prevention systems (WIDS/WIPS) capable of detecting and blocking suspicious deauthentication frames to prevent exploitation. 3. Monitor network traffic for unusual deauth frame activity, which may indicate attempted exploitation. 4. Engage with Atomberg to obtain firmware updates or security advisories; prioritize applying patches once available. 5. Implement strong Wi-Fi security measures such as WPA3 and robust access point configurations to reduce the attack surface. 6. Educate users and administrators about the risks of wireless attacks and encourage reporting of unusual device behavior. 7. Consider replacing vulnerable devices if no timely patch is forthcoming, especially in sensitive environments. 8. Maintain an inventory of IoT devices to quickly identify and respond to vulnerabilities in deployed hardware.
