Stranger: An Automata-Based String Analysis Tool for PHP

  • Conference paper

Part of the Lecture Notes in Computer Science book series (LNTCS,volume 6015)

Abstract

Stranger is an automata-based string analysis tool for finding and eliminating string-related security vulnerabilities in PHP applications. Stranger uses symbolic forward and backward reachability analyses to compute the possible values that the string expressions can take during program execution. Stranger can automatically (1) prove that an application is free from specified attacks or (2) generate vulnerability signatures that characterize all malicious inputs that can be used to generate attacks.

Keywords

  • Dependency Graph
  • Reachability Analysis
  • Strongly Connected Component
  • Attack Pattern
  • Vulnerability Signature

These keywords were added by machine and not by the authors. This process is experimental and the keywords may be updated as the learning algorithm improves.
