TITLE:
OSIsoft PI Server Insecure Authentication Process Security Issue

SECUNIA ADVISORY ID:
SA36909

VERIFY ADVISORY:
http://secunia.com/advisories/36909/

DESCRIPTION:
A security issue has been reported in OSIsoft PI Server, which can be
exploited by malicious people to potentially disclose sensitive
information and manipulate certain data.

The security issue is caused due to insufficient encryption being
used during the authentication process. This can be exploited to
potentially obtain login credentials and gain access to the PI Server
databases.

Successful exploitation requires that PI User accounts are in use.

SOLUTION:
Update to version 3.4.380 or later and migrate to the integrated
Windows authentication, or follow the workaround steps described in
the vendor's advisory.

PROVIDED AND/OR DISCOVERED BY:
Eyal Udassin, Jonathan Afek, and Yaron Budowsky of C4 Security
