TITLE:
Folder Lock Weak Password Encryption Security Issue

SECUNIA ADVISORY ID:
SA31559

VERIFY ADVISORY:
http://secunia.com/advisories/31559/

CRITICAL:
Not critical

IMPACT:
Exposure of sensitive information

WHERE:
Local system

SOFTWARE:
Folder Lock 5.x
http://secunia.com/product/19629/

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
