CVE-2023-3434Public exploitNetwork attack vector

Attacker-selected QRC resource opening via crafted hyperlink

Published Jul 14, 2023 · Updated Oct 22, 2024

Improper hyperlink validation in Savoir-faire Linux Jami 20222284 on Windows allows remote attackers to invoke a QRC URL through a message. The message hyperlink handler renders a custom HTML anchor as a normal link, then passes its unvalidated href string to Windows, which resolves it under qrc:/components/. A recipient must click the crafted link; the demonstrated result is an attempt to open an attacker-selected internal QRC resource, not established arbitrary code execution.
