Query: Characterizing Improper Input Validation Vulnerabilities of Mobile
  Crowdsourcing Services   Mobile crowdsourcing services (MCS), enable fast and economical data
acquisition at scale and find applications in a variety of domains. Prior work
has shown that Foursquare and Waze (a location-based and a navigation MCS) are
vulnerable to different kinds of data poisoning attacks. Such attacks can be
upsetting and even dangerous especially when they are used to inject improper
inputs to mislead users. However, to date, there is no comprehensive study on
the extent of improper input validation (IIV) vulnerabilities and the
feasibility of their exploits in MCSs across domains. In this work, we leverage
the fact that MCS interface with their participants through mobile apps to
design tools and new methodologies embodied in an end-to-end feedback-driven
analysis framework which we use to study 10 popular and previously unexplored
services in five different domains. Using our framework we send tens of
thousands of API requests with automatically generated input values to
characterize their IIV attack surface. Alarmingly, we found that most of them
(8/10) suffer from grave IIV vulnerabilities which allow an adversary to launch
data poisoning attacks at scale: 7400 spoofed API requests were successful in
faking online posts for robberies, gunshots, and other dangerous incidents,
faking fitness activities with supernatural speeds and distances among many
others. Lastly, we discuss easy to implement and deploy mitigation strategies
which can greatly reduce the IIV attack surface and argue for their use as a
necessary complementary measure working toward trustworthy mobile crowdsourcing
services.
