Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.

NVD · unedited
The Elink Smart eSmartCam (com.cn.dq.ipc) application 2.1.5 for Android contains hardcoded AES encryption keys that can be extracted from a binary file. Thus, encryption can be defeated by an attacker who can observe packet data (e.g., over Wi-Fi).

Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.

dbcve analysis · high confidence

The Elink Smart eSmartCam Android application version 2.1.5 contains hardcoded AES encryption keys embedded in its binary. An attacker can extract these keys by reverse-engineering the APK, then use them to decrypt network traffic captured over Wi-Fi, effectively defeating the application's encryption mechanism.

MitigationReplace hardcoded AES keys with proper key management: use Android Keystore for key storage, implement secure key exchange protocols, or generate unique per-instance keys. Re-release the application and notify users to update.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.

dbcve checks

Work through these to decide whether this CVE applies to you.

  1. Check installed eSmartCam version
    On the Android device, navigate to Settings > Apps > eSmartCam and view the version number. Alternatively, use ADB command: adb shell dumpsys package | grep -i esmartcam
    Affected if The installed version is exactly 2.1.5
  2. Obtain the application APK
    Extract the APK from the device using ADB: adb shell pm path com.elinksmart.esmartcam, then pull: adb pull /data/app/.../base.apk. Or download the APK from the original source.
    Affected if You have access to the APK file for analysis
  3. Search APK for hardcoded AES keys
    Decompile the APK using jadx or apktool. Search decompiled Java/SMALI files and resources for hardcoded encryption keys: look for 16-byte, 24-byte, or 32-byte hex strings that may represent AES-128, AES-192, or AES-256 keys. Use grep for patterns like 'key', 'aes', or large hex strings.
    Affected if Hardcoded AES encryption keys are found embedded in the APK binary or resources
  4. Verify network traffic vulnerability
    Configure a proxy (e.g., Burp Suite,mitmproxy) or use tcpdump to capture network traffic from the device while using the app. Attempt to decrypt any captured traffic using the extracted keys.
    Affected if Network traffic can be decrypted using extracted hardcoded keys, indicating the encryption is defeated

User is affected if eSmartCam version 2.1.5 is installed and the APK contains hardcoded AES keys that can be extracted to decrypt network communications.

Mitigation

Replace hardcoded AES keys with proper key management: use Android Keystore for key storage, implement secure key exchange protocols, or generate unique per-instance keys. Re-release the application and notify users to update.
