Simptomi
Kada instalirate bilo koju sigurnosnu verziju sustava .NET Framework u rujnu 2018 da biste riješili cve-2018-8421 (.NET Framework za daljinsko izvršavanje koda), tijekovi rada u sustavu SharePoint ne funkcioniraju. Kada se taj problem pojavi, zapisan je unos pogreške koji nalikuje sljedećem:
<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"…
Stavka pogreške upućuje na to da Sistemski. CodeDom. CodeBinaryOperatorExpression nije uvršten u ovlaštene vrste.
Dodatne informacije o sigurnosnim ažuriranjima za .NET u rujnu potražite na stranici Microsoft .net Blog.
Uzrok
Workflow Foundation (WF) izvršava tijekove rada samo kada su sve ovisne vrste i sklopovi ovlašteni u datoteci sustava .NET config (ili ga izravno dodaju putem koda) na sljedećem stablu:
<configuration>
<System.Workflow.ComponentModel.WorkflowCompiler>
<authorizedTypes>
<targetFx>
No nakon ažuriranja neke vrste koje se koriste u tijekovima rada sustava SharePoint koje su prethodno nisu potrebne sada su obavezne.
Rješenje
Da biste riješili taj problem, primijenite odgovarajuća sigurnost i nebezbednosna ažuriranja iz sljedećih članaka iz baze znanja:
4461501 Opis sigurnosnog ažuriranja za SharePoint Enterprise Server 2016: Studeni 13, 2018 4461508 Studeni 13, 2018, Kumulativno ažuriranje za SharePoint Foundation 2013 (KB4461508) 4461510 Studeni 13, 2018, Kumulativno ažuriranje za SharePoint Enterprise Server 2013 (KB4461510) 4011713 Studeni 13, 2018, ažuriranje za SharePoint Foundation 2010 (KB4011713) 4461528 Studeni 13, 2018, Kumulativno ažuriranje za SharePoint Server 2010 (KB4461528)
Napomene
-
Kada instalirate ažuriranje, čarobnjak za konfiguraciju proizvoda sustava SharePoint mora se pokrenuti da bi se popravak potpuno primijenio.
-
Neke treće strane ili prilagođene akcije tijeka rada mogu imati dodatne ovisnosti. Ako osjetite ponašanje koje je slično problemu, ali se ne raspravlja u ovom članku, obratite se programeru akcije tijeka rada za pomoć.
Zaobilazno rješenje
Da biste zaobišli taj problem, izričito dodajte potrebne vrste u datoteku web. config svih aplikacija. Iako su navedeni Ručni koraci, preporučujemo vam da koristite metodu skripte.
Da biste zaobilazno riješili taj problem, eksplicitno dodajte potrebne vrste u datoteke web. config svih aplikacija.
Za SharePoint 2013 i novije verzije
U sustavu SharePoint 2013 i novijim verzijama dodajte sljedeće retke:
<authorizedType Assembly="System, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089" NameSpace="System.CodeDom" TypeName="CodeBinaryOperatorExpression" Authorized="True" />

Verzije sustava SharePoint starije od sustava SharePoint 2013
Za verzije sustava SharePoint stariju od 2013 dodajte sljedeće retke:
<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="CodePropertyReferenceExpression" Authorized="True" />
Preporučujemo da umjesto izravnog mijenjanja postojećih datoteka pokrenete sljedeću skriptu.
NapomenaNeki od motora tijeka rada drugih proizvođača mogu zahtijevati dodavanje dodatnih vrsta. Ako je to slučaj, obratite se proizvođaču da biste saznali više o obaveznim vrstama, a zatim prilagodite skriptu u skladu s tim.
Sljedeća skripta mijenja web. config za sve web-aplikacije da biste dodali potrebne unose. Ova skripta dodaje te vrste za postojeće web-aplikacije i aplikacije stvorene nakon izvođenja skripte. Skripta bi se trebala pokrenuti samo jednom na bilo kojem web-pristupnom poslužitelju na farmi (ažurirat će sve poslužitelje).
<#
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.
