This Service Pack introduces options to control the operation of AutoLISP and VBA applications in AutoCAD. The new controls provide the following security measures:

• Minimize the possibility of loading and running unauthorized or malicious AutoLISP and VBA applications by controlling the folder location from which AutoLISP and VBA applications are automatically loaded (AUTOLOADPATH system variable).
• Limit the impact of malicious AutoLISP and VBA applications by disabling autoloading of default AutoLISP and VBA applications (AUTOLOAD system variable).
• Facilitate the cleanup process by completely disabling AutoLISP at startup (/nolisp startup switch).

For more information see this document.

Note: To enable the autoloading changes to acad.dvb, uninstall the AutoCAD 2013 VBA Enabler, and download and install the latest AutoCAD 2013 VBA module that was updated for the changes made in Service Pack 1 for AutoCAD 2013.

New /nolisp Startup Switch

Start AutoCAD with this switch to disable AutoLISP execution in the current AutoCAD session, including all LSP, FAS, and VLX files. This switch is useful for preventing malicious AutoLISP code from automatically loading and executing.

Disabling AutoLISP has the following effects:

• Attempting to load any LISP file will fail.
• Attempting to copy and paste AutoLISP code into the Command window will fail silently.

Note: Disabling AutoLISP will prevent the Express Tools and some AutoCAD command tools from functioning and should only be used in emergency situations.

LISPENABLED (System Variable)

Indicates whether AutoLISP is enabled for the current AutoCAD session.

(Read-only)
Type: Integer
Saved in: Not saved
Initial value: 1

0 - AutoLISP is disabled
1 - AutoLISP is enabled

Disabling AutoLISP has the following effects:

• Attempting to load any LISP file will fail.
• Attempting to copy and paste AutoLISP code into the Command window will fail silently.

AUTOLOAD (System Variable)

Controls whether AutoCAD autoloads acad.lsp/fas/vlx, acaddoc.lsp/fas/vlx, acad.dvb files.

Type: Integer
Saved in: Named Profile/Registry
Initial value: 1

Values:
0 - None of the following 7 AutoLISP/VBA files will be automatically loaded

• acad.lsp
• acad.fas
• acad.vlx
• acaddoc.lsp
• acaddoc.fas
• acaddoc.vlx
• acad.dvb

AUTOLOADPATH (System Variable)

Controls the folder from where AutoCAD loads acad.lsp/fas/vlx, acaddoc.lsp/fas/vlx, acad.dvb files.

Type: String
Saved in: Named Profile/Registry
Initial value: ""

Valid strings include the following:
"<folder path or paths separated by semicolons>" = Automatically loads the acad.lsp/fas/vlx, acaddoc.lsp/fas/vlx, acad.dvb files only in the specified folders and no other locations, including the current drawing folder. To minimize the possibility of loading a malicious application, always set the AUTOLOADPATH system variable to the unique folder where your authorized applications are located.

"" (empty string) or "." (period) - No path restriction. Automatically loads the acad.lsp/fas/vlx, acaddoc.lsp/fas/vlx, acad.dvb files found in the AutoCAD startup folder, the drawing folder, and the AutoCAD search path, in that order. This duplicates AutoCAD 2012 behavior and is not recommended.

Changes to acad2013.lsp and acad2013doc.lsp Autoloading Behavior

The acad2013.lsp and acad2013doc.lsp files will now be loaded only from their default installation folders:
   <install folder>\Support
   <install folder>\Support\<language>

Changes to the Options Dialog Box

The "Load acad.lsp with every drawing" checkbox on the System tab of the Options dialog box (ACADLSPASDOC system variable) is disabled when AUTOLOAD or LISPENABLED has a value of 0.

Recommended Setup and Repair Workflow

For the best protection from malicious AutoLISP and VBA applications set AUTOLOADPATH to a unique folder location and set AUTOLOAD to 1.

If your installation has already been impacted by a malicious application that runs on startup, following these general steps:

1. Start your AutoCAD-based product with the /nolisp startup switch.
2. Find and remove all malicious code.
3. Repair any affected files.
4. Set AUTOLOADPATH to a unique folder location and set AUTOLOAD to 1.

After taking these steps, you can remove the /nolisp startup switch from the shortcut properties of the program's desktop icon, and resume the normal operation of your AutoCAD-based application.
