Description

House price suggestion / prediction service using cutting-edge neural network machine learning algorithm.

Feature List

Given a sufficient training data set, the service can suggest a reasonable price for the house. The user can query with the following features:

  • Number of bedrooms
  • Number of bathrooms
  • Sq. Ft. of the house
  • Number of crimes per town

The size of training data set can be between 500 and 1000, for the time being.

Vulnerability

Vuln 1

In main function in service.cc, the service reads in user-controlled amount of data into a statically sized stack buffer when the predicted price of the house is $13,370,000. The attacker can train specifically such that one can get deterministic output.

Generic class of vulnerability

Stack buffer overflow

CWE classification

CWE-121: Stack-based Buffer Overflow

Challenges

  • Lots of floating point math computations

Difficulty

  • Discovery: easy
  • Proving: medium
  • Patching: easy
