Cisco AAA/Identity/Nac:: ISE V1.1 NAD 6500 Failed To Decrypt Key; Cisco VPN:: 2691 - Packets Not Getting Encrypt And Decrypt IPSEC; Cisco VPN:: 2581 - Decrypt / Mac Verify Failed Error; Cisco VPN:: RV042 Router Doesn't Encrypt But Does Decrypt; Cisco Switching/Routing:: 1811W - Packets Not Getting Encrypt And Decrypt IPSEC. Explanation The MAC verify processing failed. This might be caused by the use of the wrong key by either party during the MAC calculations. This activity could be considered a hostile event. The Encryption API uses a unique encryption key for your account/machine to encrypt the data. That means that a config file encrypted on one machine cannot be decrypted on another. So you will have to encrypt the config file on the XP machine, or use a custom encryption key which you then have to install onto the machine in order for you to.

we see a strange message in our WLC logs, which occurs quite often (>10 times a day):Decrypt errors occurred for client [MAC-Adress] using WPA key on 802.11b/g interface of AP [MAC-Adress]The MAC-Adresses of the affected clients are varying as well as the APs reporting the error.The clients are Notebooks, Cisco IP-Phones and Nokia-DualBand-Phones.
Even more frequently we see the following message in the log:
%ETHOIP-3-PING_TRANSMIT_FAILED: ethoip_ping.c:227 send_eoip_ping: Failed to tx Ethernet over IP ping rc=5.
We use TKIP as Encryption and EAP-Fast as well as LEAP as Authentication (Cisco ACS).The WLC is an 2106, the APs are 1242AG. We don't recognize any problems placing calls or talking over these phones. It's just these messages in the log that concern me.

This article provides a solution to an issue in which you are not able to connect to a virtual machine (VM) using RDP with error: CredSSP encryption oracle remediation.

Original product version: Virtual Machine running Windows
Original KB number: 4295591

Symptoms

Consider the following scenario:

The Credential Security Support Provider protocol (CredSSP) updates for CVE-2018-0886 are applied to a Windows VM (remote server) in Microsoft Azure or on a local client.
You try to make a remote desktop (RDP) connection to the server from the local client.

In this scenario, you receive the following error message:

An authentication error has occurred. The function requested is not supported. Remote computer: <computer name or IP>. This could be due to CredSSP encryption oracle remediation. For more information, see https://go.microsoft.com/fwlink/?linkid=866660.

How to verify that the CredSSP update is installed

Check the update history for the following updates, or check the version of TSpkg.dll.

Operating system	TSpkg.dll version with CredSSP update	CredSSP update
Windows 7 Service Pack 1 / Windows Server 2008 R2 Service Pack 1	6.1.7601.24117	KB4103718 (Monthly Rollup)

KB4103715 (Security-only update)
RS1 - Windows 10 Version 1607 / Windows Server 2016	10.0.14393.2248	KB4103723
RS2 - Windows 10 Version 1703	10.0.15063.1088	KB4103731
RS3 - Windows 10 1709	10.0.16299.431	KB4103727

Cause

This error occurs if you are trying to establish an insecure RDP connection, and the insecure RDP connection is blocked by an Encryption Oracle Remediation policy setting on the server or client. This setting defines how to build an RDP session by using CredSSP, and whether an insecure RDP is allowed.

See the following interoperability matrix for scenarios that are either vulnerable to this exploit or cause operational failures.

-	-	Server	-	-	-
-	-	Updated	Force updated clients	Mitigated	Vulnerable
Client	Updated	Allowed	Blocked²	Allowed	Allowed
Force updated clients	Blocked	Allowed	Allowed	Allowed
Mitigated	Blocked ¹	Allowed	Allowed	Allowed
Vulnerable	Allowed	Allowed	Allowed	Allowed

Examples

¹ The client has the CredSSP update installed, and Encryption Oracle Remediation is set to Mitigated. This client will not RDP to a server that does not have the CredSSP update installed.

² The server has the CredSSP update installed, and Encryption Oracle Remediation is set to Force updated clients. The server will block any RDP connection from clients that do not have the CredSSP update installed.

Resolution

To resolve the issue, install CredSSP updates for both client and server so that RDP can be established in a secure manner. For more information, see CVE-2018-0886 | CredSSP Remote Code Execution Vulnerability.

How to install this update by using Azure Serial console

Sign in to the Azure portal, select Virtual Machine, and then select the VM.
Scroll down to the Support + Troubleshooting section, and then click Serial console (Preview). The serial console requires Special Administrative Console (SAC) to be enabled within the Windows VM. If you do not see SAC> in the console (as shown in the following screenshot), go to the 'How to install the update by using Remote PowerShell' section in this article.
