Description

Error Message

500 - Internal Server Error

 

Cause

Microsoft has acknowledged a scripting engine memory corruption vulnerability and recommends disabling jscript.dll. Enterprise Vault utilizes the jscript.dll in search related functionality. 

 

Resolution

At this time the only option available is to re-enable jscript.dll on the Enterprise Vault servers where search related functions occur until Microsoft publishes a proper fix for the potential memory corruption vulnerability.

Note: For a 64-bit system, enter the following command at an administrative command prompt. It may be necessary to take ownership of the file in order for the command to function properly.  This can be done from the Security tab Advanced properties on the file.  

cacls %windir%\syswow64\jscript.dll /E /R everyone

Note: An IISreset may be required once the command has been executed.
