curl 8.5.0-8.13.9 - Improper Certificate Validation in QUIC HTTP/3 with wolfSSL
Title source: llmExploitation Summary
EIP tracks 1 public exploit for CVE-2025-5025. PoCs published by KiPhuong.
AI-analyzed exploit summary This repository contains a functional proof-of-concept for CVE-2025-5025, demonstrating an HTTP/3-based attack using Dockerized client and server components. The setup includes a real server, a fake server, and a client configured with wolfSSL, nghttp3, and ngtcp2 to exploit the vulnerability.
Description
libcurl supports *pinning* of the server certificate public key for HTTPS transfers. Due to an omission, this check is not performed when connecting with QUIC for HTTP/3, when the TLS backend is wolfSSL. Documentation says the option works with wolfSSL, failing to specify that it does not for QUIC and HTTP/3. Since pinning makes the transfer succeed if the pin is fine, users could unwittingly connect to an impostor server without noticing.
