zkSBOM: Privacy-Preserving SBOM Sharing with Zero-Knowledge Sets
Tom Sorger, Eric Cornelissen, Aman Sharma +3
Software Bills of Materials (SBOMs) are increasingly mandated by regulators, yet existing sharing mechanisms impose a binary choice between full disclosure and full opacity. This e…
Granite: Granular Runtime Enforcement for GitHub Actions Permissions
Mojtaba Moazen, Amir. M Ahmadian, Musard Balliu
Modern software projects use automated CI/CD pipelines to streamline their development, build, and deployment processes. GitHub Actions is a popular CI/CD platform that enables pro…
NodeShield: Runtime Enforcement of Security-Enhanced SBOMs for Node.js
Eric Cornelissen, Musard Balliu
The software supply chain is an increasingly common attack vector for malicious actors. The Node.js ecosystem has been subject to a wide array of attacks, likely due to its size an…
Securing P4 Programs by Information Flow Control
Anoud Alshnakat, Amir M. Ahmadian, Musard Balliu +2
Software-Defined Networking (SDN) has transformed network architectures by decoupling the control and data-planes, enabling fine-grained control over packet processing and forwardi…
Sharing without Showing: Secure Cloud Analytics with Trusted Execution Environments
Marcus Birgersson, Cyrille Artho, Musard Balliu
Many applications benefit from computations over the data of multiple users while preserving confidentiality. We present a solution where multiple mutually distrusting users' data…
GHunter: Universal Prototype Pollution Gadgets in JavaScript Runtimes
Eric Cornelissen, Mikhail Shcherbakov, Musard Balliu
Prototype pollution is a recent vulnerability that affects JavaScript code, leading to high impact attacks such as arbitrary code execution. The vulnerability is rooted in JavaScri…
Disjunctive Policies for Database-Backed Programs
Amir M. Ahmadian, Matvey Soloviev, Musard Balliu
When specifying security policies for databases, it is often natural to formulate disjunctive dependencies, where a piece of information may depend on at most one of two dependenci…
Unveiling the Invisible: Detection and Evaluation of Prototype Pollution Gadgets with Dynamic Taint Analysis
Mikhail Shcherbakov, Paul Moosbrugger, Musard Balliu
For better or worse, JavaScript is the cornerstone of modern Web. Prototype-based languages like JavaScript are susceptible to prototype pollution vulnerabilities, enabling an atta…
Security Properties through the Lens of Modal Logic
Matvey Soloviev, Musard Balliu, Roberto Guanciale
We introduce a framework for reasoning about the security of computer systems using modal logic. This framework is sufficiently expressive to capture a variety of known security pr…
Silent Spring: Prototype Pollution Leads to Remote Code Execution in Node.js
Mikhail Shcherbakov, Musard Balliu, Cristian-Alexandru Staicu
Prototype pollution is a dangerous vulnerability affecting prototype-based languages like JavaScript and the Node.js platform. It refers to the ability of an attacker to inject pro…
Vivienne: Relational Verification of Cryptographic Implementations in WebAssembly
Rodothea Myrsini Tsoupidi, Musard Balliu, Benoit Baudry
This paper explores the use of relational symbolic execution to counter timing side channels in WebAssembly programs. We design and implement Vivienne, an open-source tool to autom…
InSpectre: Breaking and Fixing Microarchitectural Vulnerabilities by Formal Analysis
Roberto Guanciale, Musard Balliu, Mads Dam
The recent Spectre attacks has demonstrated the fundamental insecurity of current computer microarchitecture. The attacks use features like pipelining, out-of-order and speculation…
An Empirical Study of Information Flows in Real-World JavaScript
Cristian-Alexandru Staicu, Daniel Schoepe, Musard Balliu +2
Information flow analysis prevents secret or untrusted data from flowing into public or trusted sinks. Existing mechanisms cover a wide array of options, ranging from lightweight t…
Epistemic Temporal Logic for Information Flow Security
Musard Balliu, Mads Dam, Gurvan Le Guernic
Temporal epistemic logic is a well-established framework for expressing agents knowledge and how it evolves over time. Within language-based security these are central issues, for…
