Gejala
Setelah Anda menginstal pembaruan keamanan 2018 .NET Framework untuk mengatasi masalah CVE-2018-8421 (kerentanan eksekusi kode jarak jauh .NET Framework), alur kerja SharePoint Out-of-The-Box berhenti bekerja. Saat masalah ini terjadi, entri kesalahan yang menyerupai yang berikut ini dicatat:
<Date> <Time> w3wp.exe (0x1868) 0x22FC SharePoint Foundation Workflow Infrastructure 72fs Unexpected RunWorkflow: Microsoft.SharePoint.SPException: <Error><CompilerError Line="-1" Column="-1" Text="Type System.CodeDom.CodeBinaryOperatorExpression is not marked as authorized in the application configuration file." /><CompilerError Line="-1" Column="-1" Text="Type System.CodeDom.CodeBinaryOperatorExpression is not marked as authorized in the application configuration file." /><CompilerError Line="-1" Column="-1" Text="Type System.CodeDom.CodeBinaryOperatorExpression is not marked as authorized in the application configuration file." /><CompilerError Line="-1" Column="-1" Text="Type System.CodeDom.CodeBinaryOperatorExpression is not marked as authorized in the application configuration file." /><CompilerError Line="-1" Column="-1" Text="Type System.CodeDom.CodeBinaryOperatorExpression is not marked as authorized in the application configuration file." /><CompilerError Line="-1" Column="-1" Text="Type System.CodeDom.CodeBinaryOperatorExpression is not marked as authorized in the application configuration file." /><CompilerError Line="-1" Column="-1" Text="Type System.CodeDom.CodeBinaryOperatorExpression is not marked as authorized in the application configuration file." /><CompilerError Line="-1" Column="-1"…
Entri kesalahan menyarankan bahwa System. CodeDom. CodeBinaryOperatorExpression tidak disertakan dalam tipe yang diizinkan.

Penyebab
Alur kerja dasar (WF) menjalankan alur kerja hanya ketika semua tipe dan rakitan dependen diotorisasi dalam file .NET config (atau ditambahkan secara eksplisit melalui kode) dalam pohon berikut:
<configuration>
<System.Workflow.ComponentModel.WorkflowCompiler>
<authorizedTypes>
<targetFx>
Namun, setelah pembaruan, beberapa tipe yang digunakan oleh alur kerja SharePoint Out-of-Box yang sebelumnya tidak diperlukan sekarang diperlukan.
Pemecahan Masalah
Untuk mengatasi masalah ini, Terapkan pembaruan keamanan dan nonsecurity yang sesuai dari artikel Basis Pengetahuan berikut:
4461501 Deskripsi pembaruan keamanan untuk SharePoint Enterprise Server 2016:13 November 2018 4461508 November 13, 2018, pembaruan kumulatif untuk SharePoint Foundation 2013 (KB4461508) 4461510 November 13, 2018, pembaruan kumulatif untuk SharePoint Enterprise Server 2013 (KB4461510) 4011713 November 13, 2018, pembaruan untuk SharePoint Foundation 2010 (KB4011713) 4461528 November 13, 2018, pembaruan kumulatif untuk SharePoint Server 2010 (KB4461528)
Catatan
-
Setelah pembaruan diinstal, panduan konfigurasi SharePoint Products harus dijalankan agar perbaikan diterapkan sepenuhnya.
-
Beberapa tindakan alur kerja pihak ketiga atau kustom mungkin memiliki dependensi tambahan. Jika Anda mengalami perilaku yang sama dengan masalah ini tetapi tidak dibahas dalam artikel ini, silakan baca pengembang tindakan alur kerja untuk bantuan.
Penyelesaian Masalah
Untuk mengatasi masalah ini, tambahkan tipe yang diperlukan secara eksplisit ke file web. config dari semua aplikasi. Meskipun langkah-langkah manual disediakan, kami menyarankan agar Anda menggunakan metode skrip.
Untuk mengatasi masalah ini, tambahkan tipe yang diperlukan secara eksplisit ke file web. config dari semua aplikasi.
Untuk SharePoint 2013 dan versi yang lebih baru
Untuk SharePoint 2013 dan versi yang lebih baru, tambahkan baris berikut:
<authorizedType Assembly="System, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089" NameSpace="System.CodeDom" TypeName="CodeBinaryOperatorExpression" Authorized="True" />
<authorizedType Assembly="System, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089" NameSpace="System.CodeDom" TypeName="CodePrimitiveExpression" Authorized="True" />
<authorizedType Assembly="System, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089" NameSpace="System.CodeDom" TypeName="CodeMethodInvokeExpression" Authorized="True" />
<authorizedType Assembly="System, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089" NameSpace="System.CodeDom" TypeName="CodeMethodReferenceExpression" Authorized="True" />
<authorizedType Assembly="System, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089" NameSpace="System.CodeDom" TypeName="CodeFieldReferenceExpression" Authorized="True" />
<authorizedType Assembly="System, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089" NameSpace="System.CodeDom" TypeName="CodeThisReferenceExpression" Authorized="True" />
<authorizedType Assembly="System, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089" NameSpace="System.CodeDom" TypeName="CodePropertyReferenceExpression" Authorized="True" />
Untuk versi SharePoint yang lebih lama dari SharePoint 2013
Untuk versi SharePoint yang lebih lama dari 2013, tambahkan baris berikut ini sebagai gantinya:
<authorizedType Assembly="System, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089" NameSpace="System.CodeDom" TypeName="CodeBinaryOperatorExpression" Authorized="True" />
<authorizedType Assembly="System, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089" NameSpace="System.CodeDom" TypeName="CodePrimitiveExpression" Authorized="True" />
<authorizedType Assembly="System, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089" NameSpace="System.CodeDom" TypeName="CodeMethodInvokeExpression" Authorized="True" />
<authorizedType Assembly="System, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089" NameSpace="System.CodeDom" TypeName="CodeMethodReferenceExpression" Authorized="True" />
<authorizedType Assembly="System, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089" NameSpace="System.CodeDom" TypeName="CodeFieldReferenceExpression" Authorized="True" />
<authorizedType Assembly="System, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089" NameSpace="System.CodeDom" TypeName="CodeThisReferenceExpression" Authorized="True" />
<authorizedType Assembly="System, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089" NameSpace="System.CodeDom" TypeName="CodePropertyReferenceExpression" Authorized="True" />
Kami menyarankan Anda untuk menjalankan skrip berikut ini dan bukan memodifikasi file yang sudah ada.
Catatan Beberapa mesin alur kerja pihak ketiga mungkin memerlukan penambahan tipe tambahan. Jika demikian, hubungi pemasok Anda untuk informasi tentang tipe yang diperlukan, lalu Sesuaikan skrip yang sesuai.
Skrip berikut mengubah web. config untuk semua aplikasi web untuk menambahkan entri yang diperlukan. Skrip ini menambahkan tipe ini untuk aplikasi web yang sudah ada dan untuk aplikasi yang dibuat setelah skrip berjalan. Skrip harus dijalankan hanya satu kali di server Front-end web di dalam Farm (akan memperbarui semua server).
<#
This script adds the entries to all web.config files for all web applications in the farm.
Run this script as Farm Administrator in one of the WFEs.
This script has to run only one time.
SUMMARY:
This script uses the native SharePoint SPWebConfigModification API to deploy new updates to the web.config file for each web application on each server in the farm. Servers that are added at a later date will also get the updates applied because the API configuration is persisted in the config database. This API does not update the web.config for the central administration web application.
If you are running workflows on the central admin web application, you will have to manually update the web.config by using the steps in the referenced blog.
