RustCrypto RSA - Covert Timing Channel via Non-Constant-Time Implementation
Title source: llmExploitation Summary
EIP tracks 1 public exploit for CVE-2023-49092. PoCs published by omonuj.
AI-analyzed exploit summary This repository provides a functional exploit and remediation script for CVE-2023-49092, a Kubernetes-based configuration and mTLS validation vulnerability in the 'bleater' fanout service. The exploit neutralizes drift sources, regenerates compliant TLS certificates, and deploys a live fan-out distributor to restore secure message distribution.
Description
RustCrypto/RSA is a portable RSA implementation in pure Rust. Due to a non-constant-time implementation, information about the private key is leaked through timing information which is observable over the network. An attacker may be able to use that information to recover the key. There is currently no fix available. As a workaround, avoid using the RSA crate in settings where attackers are able to observe timing information, e.g. local use on a non-compromised computer.
