Product & Service Introduction:
===============================
PayPal is a global e-commerce business allowing payments and money transfers to be made through \
the Internet. Online money transfers serve as electronic alternatives to paying with \
traditional paper methods, such as checks and money orders. Originally, a PayPal account could \
be funded with an electronic debit from a bank account or by a credit card at the payer s \
choice. But some time in 2010 or early 2011, PayPal began to require a verified bank account \
after the account holder exceeded a predetermined spending limit. After that point, PayPal \
will attempt to take funds for a purchase from funding sources according to a specified \
funding hierarchy. If you set one of the funding sources as Primary, it will default to that, \
within that level of the hierarchy (for example, if your credit card ending in 4567 is set as \
the Primary over 1234, it will still attempt to pay money out of your PayPal balance, before \
it attempts to charge your credit card). The funding hierarchy is a balance in the PayPal \
account; a PayPal credit account, PayPal Extras, PayPal SmartConnect, PayPal Extras Master \
Card or Bill Me Later (if selected as primary funding source) (It can bypass the Balance); a \
verified bank account; other funding sources, such as non-PayPal credit cards. The recipient of \
a PayPal transfer can either request a check from PayPal, establish their own PayPal deposit \
account or request a transfer to their bank account.
PayPal is an acquirer, performing payment processing for online vendors, auction sites, and \
other commercial users, for which it charges a fee. It may also charge a fee for receiving \
money, proportional to the amount received. The fees depend on the currency used, the payment \
option used, the country of the sender, the country of the recipient, the amount sent and the \
recipient s account type. In addition, eBay purchases made by credit card through PayPal may \
incur extra fees if the buyer and seller use different currencies.
On October 3, 2002, PayPal became a wholly owned subsidiary of eBay. Its corporate headquarters \
are in San Jose, California, United States at eBay s North First Street satellite office \
campus. The company also has significant operations in Omaha, Nebraska, Scottsdale, Arizona, \
and Austin, Texas, in the United States, Chennai, Dublin, Kleinmachnow (near Berlin) and Tel \
Aviv. As of July 2007, across Europe, PayPal also operates as a Luxembourg-based bank.
On March 17, 2010, PayPal entered into an agreement with China UnionPay (CUP), China s bankcard \
association, to allow Chinese consumers to use PayPal to shop online.PayPal is planning to \
expand its workforce in Asia to 2,000 by the end of the year 2010.

Product: Marketing Application & Service (HK) 2015 Q2
Exploitation Technique:
=======================
Remote
Severity Level:
===============
Critical
Technical Details & Description:
================================
A remote code execution vulnerability has been discovered in the JDWP protocol of the PayPal \
Inc Marketing online service web-server. The vulnerability allows remote attackers to execute \
system specific code against a target system to compromise the webserver.
The Java Debug Wire Protocol (JDWP) is the protocol used for communication between a debugger \
and the Java virtual machine (VM) which it debugs (hereafter called the target VM). JDWP is \
one layer within the Java Platform Debugger Architecture (JPDA). JDWP does not use any \
authentication and could be abused by an attacker to execute arbitrary code on the affected \
server.
The tool that i used to disclose is the jdwp-shellifier. I scanned the marketing site and it \
had opened port 8000 (pre-auth) than i just executed after accepted connection my commands and \
finally disclosed a remote code execution issue.
Vulnerable Protocol(s):
[+] JDWP
Port(s):
[+] 8000
Proof of Concept (PoC):
=======================
The remote code execution web vulnerability can be exploited by remote attackers without \
privileged application user account or user interaction. For security demonstration or to \
reproduce the security vulnerability follow the provided information and steps below to \
continue.
Manual steps to reproduce the security vulnerability ...
1. Scan the site with the jdwp-shellifier tool (https://github.com/IOActive/jdwp-shellifier)
2. Open port 8000 and connect to the service without auth
3. Execute own server-side commands as root user
4. Successful reproduce of the vulnerability!
Note: Please watch the poc demo video!
Solution - Fix & Patch:
=======================
2015-04-09: Vendor Fix/Patch (PayPal Inc - Developer Team)
Security Risk:
==============
The security risk of the remote code execution vulnerability in the jdwp protocol is estimated \
as critical. (CVSS 9.3)
