CVE Reference(s):

Description


Charalambous Glafkos and George Nicolaou have discovered a security issue in Folder Lock, which can be exploited by malicious, local users to disclose sensitive information.

The security issue is caused due to the application storing the application's password using a weak encryption algorithm within the "HKEY_CURRENT_USER\Software\Microsoft\Windows\QualityControl" registry key. This can be exploited to extract the original password and gain access to locked files by decrypting the "_pack" registry value.

Successful exploitation allows access to Folder Lock protected files, but requires administrative privileges.

The security issue is confirmed in version 5.9.5. Other versions may also be affected.


Solution:
Do not rely on the security provided by Folder Lock if Administrator privileges are granted to untrusted users.

Provided and/or discovered by:
Charalambous Glafkos and George Nicolaou
