CVE-2020-7999
📋 TL;DR
The Intellian Aptus Android application version 1.0.2 contains hardcoded API keys (DOWNLOAD_API_KEY and FILE_DOWNLOAD_API_KEY), allowing attackers to bypass authentication and potentially download sensitive files or execute unauthorized operations. This affects all users of the vulnerable Android application version.

⚠️ Risk & Real-World Impact
Worst Case
Attackers could download sensitive application files, user data, or execute arbitrary operations on the device by exploiting the hardcoded keys to bypass authentication mechanisms.
Likely Case
Unauthorized access to application resources and potential data exfiltration through API calls using the exposed hardcoded keys.
If Mitigated
Limited impact if network access is restricted or if the application is isolated from sensitive systems.
🎯 Exploit Status
Exploitation requires knowledge of the hardcoded keys, which may be extracted from the application binary or network traffic.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Unknown
Vendor Advisory: Not available
Restart Required: No
Instructions:
Check for updated versions from the vendor or Google Play Store; if unavailable, consider alternative applications or workarounds.
🔧 Temporary Workarounds
Network Isolation
allRestrict network access to the application to prevent external exploitation.
Application Removal
androidUninstall the vulnerable application version to eliminate the risk.
adb uninstall <package_name>
🧯 If You Can't Patch
- Monitor network traffic for unauthorized API calls using the hardcoded keys.
- Implement strict network segmentation to limit the application's access to sensitive resources.
🔍 How to Verify
Check if Vulnerable:
Check the application version in Android settings or via 'adb shell dumpsys package <package_name>' and verify if it is 1.0.2.Check Version:
adb shell dumpsys package com.intellian.aptus | grep versionNameVerify Fix Applied:
Update to a newer version if available and confirm the version has changed from 1.0.2.📡 Detection & Monitoring
Log Indicators:
- Unusual API access patterns or failed authentication attempts in application logs.
Network Indicators:
- Network traffic containing the hardcoded API keys in requests to download endpoints.
SIEM Query:
Not applicable for typical SIEM setups due to mobile application nature.
