  Security researchers at Prizm Labs discovered a critical zero-click remote code execution (RCE) vulnerability in the SuperNote Nomad e-ink tablet. Exploiting a flaw in the device's update mechanism, an attacker could remotely execute arbitrary code with root privileges by sending a specially crafted OTA update notification via a malicious Wi-Fi access point. The attack requires no user interaction, making it particularly dangerous. The vulnerability stemmed from insufficient validation of update packages, allowing malicious firmware to be installed. Prizm Labs responsibly disclosed the vulnerability to SuperNote, who promptly released a patch. This vulnerability highlights the importance of robust security measures even in seemingly simple devices like e-readers.

  This blog post by Prizm Labs details the discovery and exploitation of a zero-click remote code execution (RCE) vulnerability in the SuperNote A5X and A6X e-ink tablets, specifically those running firmware version 3.4.0.33. A zero-click exploit allows an attacker to compromise a device without requiring any interaction from the user. The vulnerability stemmed from the insecure implementation of the OTA (Over-The-Air) update mechanism.

  The researchers began their investigation by analyzing the network traffic during an OTA update. They observed that the update process involved downloading a signed firmware image via HTTPS. While the use of HTTPS provided encryption, it did not protect against malicious manipulation if the attacker could compromise the update server or perform a man-in-the-middle attack. Crucially, the researchers found that the device did not validate the signature of the downloaded update package before writing it to the internal flash memory. This oversight allowed them to craft a malicious firmware update package containing arbitrary code.

  The exploit process involved several steps. First, a malicious update package was constructed. This package contained a modified boot image, effectively replacing the legitimate SuperNote operating system with a malicious one. The malicious boot image included a modified init script designed to establish a reverse shell back to the attacker's machine, granting them full control over the device.

  To deliver the malicious update, the researchers leveraged a classic man-in-the-middle attack technique, using ARP spoofing. ARP spoofing allows an attacker to intercept traffic intended for another device on the local network by impersonating its MAC address. By poisoning the ARP cache of the SuperNote device, the researchers redirected the device's OTA update request to their own malicious server, hosting the crafted update package.

  When the SuperNote attempted to update, it downloaded the malicious package from the attacker's server. Due to the lack of pre-installation signature verification, the device accepted and applied the malicious update. Upon reboot, the modified init script within the malicious boot image executed, establishing the reverse shell and granting the attacker complete control. This access allowed them to execute arbitrary commands, exfiltrate sensitive data, and essentially take full ownership of the device.

  The researchers highlighted the severity of this vulnerability, as it permitted silent and remote compromise of the targeted device. They responsibly disclosed the vulnerability to Ratta Supernote, the manufacturer of the device, who subsequently released a patched firmware version addressing the issue. The post concludes by emphasizing the importance of secure OTA update implementations and the need for robust security measures in internet-connected devices.
