CVE-2023-47354 is a high-severity vulnerability identified in the PowerOffWidgetReceiver function of the Super Reboot (Root) Recovery application, version 1.0.3. This vulnerability allows an attacker with limited privileges (local access with low privileges) to send a crafted intent to the affected component, which can trigger an arbitrary device reset or power off. The vulnerability is rooted in insufficient validation or improper handling of intents by the PowerOffWidgetReceiver, enabling unauthorized control over device power management functions. The CVSS 3.1 base score of 7.8 reflects the high impact on confidentiality, integrity, and availability, as the attacker can disrupt device operations by forcing unexpected reboots or shutdowns. The attack vector is local (AV:L), requiring the attacker to have some level of access to the device, but no user interaction is needed (UI:N). The vulnerability does not require elevated privileges beyond low-level permissions (PR:L), making it easier to exploit by local attackers or malicious apps with limited permissions. The scope is unchanged (S:U), meaning the impact is confined to the vulnerable component and device itself. Although no known exploits in the wild have been reported, the potential for denial of service and operational disruption is significant, especially for devices relying on this recovery tool for root-level operations or maintenance. The lack of vendor or product details limits the ability to identify the exact ecosystem affected, but the vulnerability specifically targets a root recovery utility, which is typically used on rooted Android devices or specialized environments where users require advanced reboot and recovery options.

For European organizations, the primary impact of CVE-2023-47354 lies in operational disruption and potential denial of service on devices running the vulnerable Super Reboot (Root) Recovery tool. Organizations that rely on rooted Android devices for specialized tasks, such as mobile device management, field operations, or development, may face unexpected device reboots or shutdowns, leading to loss of productivity and potential data loss. The high impact on confidentiality, integrity, and availability means that sensitive operations could be interrupted, and unauthorized resets could be used as part of a broader attack chain to destabilize device fleets. Although exploitation requires local access, insider threats or compromised devices could leverage this vulnerability to cause disruption. In sectors such as manufacturing, logistics, or critical infrastructure where rooted devices might be used for control or monitoring, this vulnerability could pose a risk to operational continuity. Additionally, the lack of patches or vendor guidance increases the risk exposure until mitigations are implemented.

To mitigate CVE-2023-47354, European organizations should: 1) Audit and inventory devices to identify any running Super Reboot (Root) Recovery v1.0.3 or similar root recovery tools. 2) Restrict local access to devices, enforcing strict user permissions and preventing installation of untrusted applications that could exploit the vulnerability. 3) Implement mobile device management (MDM) policies that monitor and control the use of root utilities and restrict intent-based communications to trusted components only. 4) Where possible, replace or upgrade the vulnerable recovery tool with a patched or alternative solution that validates intents securely. 5) Educate users and administrators about the risks of rooting devices and the importance of maintaining secure configurations. 6) Monitor device logs for unusual reboot or shutdown events that could indicate exploitation attempts. 7) Engage with vendors or open-source communities to track the availability of patches or updates addressing this vulnerability. Given the absence of official patches, temporary mitigations such as disabling the PowerOffWidgetReceiver component or limiting intent reception via application hardening may reduce risk.
