🚀 Explore this insightful post from Hacker News 📖 📂 Category: 📌 Key idea: Pasquale "sid" Fiorillo discovered a critical vulnerability in GoSign Desktop <= 2.4.0 that allows an attacker to execute arbitrary code on the system through insecure updates and a TLS bypass. The exploit leverages the deactivation of TLS certificate verification when a proxy is configured, together with an update mechanism based on unsigned manifests. The vendor, Tinexta InfoCert, initially cooperative, ceased all communication after receiving the technical details, ignoring follow?up requests and releasing version 2.4.1 without any public notice or acknowledgment of the researchers. Due to this…
