CVE-2024-25731

Packet-data decryption via hardcoded AES keys

Published Mar 4, 2024 · Updated Mar 26, 2025

Hard-coded cryptographic keys in Elink Smart eSmartCam 2.1.5 for Android allow attackers to decrypt packet data observed over Wi-Fi. The Android application embeds reusable AES keys in its binary, allowing extraction and reuse against data protected with those keys. Access to observable network traffic and the application binary is required; the demonstrated consequence is loss of confidentiality for encrypted data.
