Adobe Acrobat Reader - AFParseDate JavaScript API Restrictions Bypass

# Title: Adobe Acrobat Reader AFParseDate Javascript API Restrictions

Bypass Vulnerability

# Date: 09/28/2015

# Author: Reigning Shells, based off PoC published by Zero Day Initiative

# Vendor Homepage: adobe.com

# Version: Adobe Reader and Acrobat 10.x before 10.1.14 and 11.x before

11.0.11 on Windows and OS X are vulnerable.

# Tested on: Adobe Acrobat 11.0.10 on Windows 7

# CVE : CVE-2015-3073



This vulnerability allows remote attackers to bypass API restrictions on

vulnerable installations of Adobe Reader. User interaction is required to

exploit this vulnerability in that the target must visit a malicious page

or open a malicious file.



The specific flaw exists within AFParseDate. By creating a specially

crafted PDF with specific JavaScript instructions, it is possible to bypass

the Javascript API restrictions. A remote attacker could exploit this

vulnerability to execute arbitrary code.



Adobe Reader and Acrobat 10.x before 10.1.14 and 11.x before 11.0.11 on

Windows and OS X are vulnerable.



Notes:



The code assumes you attached a DLL named exploit.txt to the PDF document

to get around attachment security restrictions.



Acrobat will execute updaternotifications.dll if it's in the same directory

as the Acrobat executable or the same directory as the document being

opened.



Credit for discovery and the initial POC that illustrates code being

executed in the privileged context (launching a URL) goes to the Zero Day

Initiative.
