AI-suggested
- Immediately update ADB-Explorer to Beta 0.9.26020 or later, where the vulnerability is fixed.
- Restrict write permissions on the App.txt settings file to trusted users only to prevent unauthorized modification.
- Implement endpoint security controls to detect and prevent unauthorized file changes and monitor for suspicious application launches.
- Educate users about the risks of launching untrusted applications or files and enforce least privilege principles to limit the impact of potential exploitation.
- Use application whitelisting to prevent execution of unauthorized or modified versions of ADB-Explorer.
- Regularly audit and monitor systems for signs of compromise, focusing on Windows endpoints used for mobile device management.
- Consider isolating development or device management environments to reduce exposure.
- If updating is not immediately possible, disable or restrict usage of ADB-Explorer until patched.
Description
ADB Explorer is a fluent UI for ADB on Windows. Prior to Beta 0.9.26020, ADB Explorer is vulnerable to Insecure Deserialization leading to Remote Code Execution. The application attempts to deserialize the App.txt settings file using Newtonsoft.Json with TypeNameHandling set to Objects. This allows an attacker to supply a crafted JSON file containing a gadget chain (e.g., ObjectDataProvider) to execute arbitrary code when the application launches and subsequently saves its settings. This vulnerability is fixed in Beta 0.9.26020.
