Philips Smart Wi-Fi LED Batten 24-Watt: Cleartext Storage of Sensitive Information

CVE-2024-9991 is a high-severity cleartext storage of sensitive information vulnerability in Philips Smart Wi-Fi LED Batten 24-Watt from Philips Lighting (Signify Innovations India), with a CVSS 4.0 base score of 7.0 out of 10. It can be exploited with physical access to the device by an unauthenticated attacker, without any action from a user. Affected Philips Smart Wi-Fi LED Batten 24-Watt versions: <1.33.1. The record does not name a fixed version, so check the vendor advisory. There is no confirmed exploitation so far. EPSS estimates a 0.15% chance of exploitation within 30 days, which is low compared with other CVEs.

Next patch cycle

High severity with no evidence of exploitation so far.

What to do

  1. Update phillips_smart_wi-fi_led_batten_24-watt_firmware to 1.33.1 or a later version.

Official description

This vulnerability exists in Philips lighting devices due to storage of Wi-Fi credentials in plain text within the device firmware. An attacker with physical access could exploit this by extracting the firmware and analyzing the binary data to obtain the plaintext Wi-Fi credentials stored on the vulnerable device. Successful exploitation of this vulnerability could allow an attacker to gain unauthorized access to the Wi-Fi network to which vulnerable device is connected.

The underlying weakness: Cleartext Storage of Sensitive Information

The product stores sensitive information in cleartext within a resource that might be accessible to another control sphere.

How developers prevent this class of flaw

  • When storing data in the cloud (e.g., S3 buckets, Azure blobs, Google Cloud Storage, etc.), use the provider's controls to encrypt the data at rest.
  • In some systems/environments such as cloud, the use of double encryption (at both the software and hardware layer) might be required, and the developer might be solely responsible for both layers, instead of shared responsibility with the administrator of the broader system/environment.
