Hierarchical Data-Flow Graphs

Authors: José Pereira, Vitor Vieira, and Alberto Simões

Published in: OASIcs, Volume 113, 12th Symposium on Languages, Applications and Technologies (SLATE 2023)

Abstract
Data-Flows are crucial to detect the dependency of statements and expressions in a programming language program. In the context of Static Application Security Testing (SAST), they are heavily used in different aspects, from detecting tainted data to understanding code dependency. In Checkmarx, these data flows are currently computed on the fly, but their efficiency is not the desired, especially when dealing with large projects. With this in mind, a new caching mechanism is being developed, based on hierarchical graphs. In this document, we discuss the basic idea behind this approach, the challenges found and the decisions put in place for the implementation. We will also share the first insights on speed improvements for a proof of concept implementation.

Type Annotation for SAST

Authors: Marco Pereira, Alberto Simões, and Pedro Rangel Henriques

Published in: OASIcs, Volume 113, 12th Symposium on Languages, Applications and Technologies (SLATE 2023)

Abstract
Static Application Security Testing (SAST) is a type of software security testing that analyzes the source code of an application to identify security vulnerabilities and coding errors. It helps detect security vulnerabilities in software code before deployment reducing the risk of exploitation by attackers. The work presented in this document describes the work performed to upgrade Checkmarx’s SAST tool allowing the execution of vulnerability detection taking into account expression types. For this to be possible, every expression in the Document Object Model needs to have a specific type assigned accordingly to the kind of operation and to the different operand types. At the current stage, this project is already supporting the expression type annotation for three programming languages: C, C++ and C#. This support has been done through the addition of a new Resolver Rule to the Resolver stage, allowing for the generalization of languages. We also compare the complexity of writing vulnerability detection queries with or without access to type information.

Down-Translating XML: The Python Way

Authors: Alberto Simões and José João Almeida

Published in: OASIcs, Volume 104, 11th Symposium on Languages, Applications and Technologies (SLATE 2022)

Abstract
Nowadays, the most used approach to process an XML file is based on the processing of a DOM structure and a set of operations that collects or edits information in the model using some kind of selectors (usually CSS-like or XPath). Nevertheless, the process of performing a depth-first walk through the DOM, and synthesizing values, is a simple way to traverse and transform an entire XML document. In this document we discuss the details on the implementation and usage of a Python package for XML document processing based on this structure. Given the existence of similar tools for other programming languages, we will mainly focus on the used approach, that takes advantage of the Python style guides and development patterns.
