CVE-2020-36767Public exploitNetwork attack vector

Command execution via unescaped dialog text

Published Oct 30, 2023 · Updated Sep 9, 2024

Shell command injection in Guillaume Vareille tinyfiledialogs before 3.8.0 allows attackers to execute commands via crafted dialog text. On Linux, the message-box path concatenates title and message strings into a shell command without neutralizing shell metacharacters. A consuming application must pass attacker-controlled text to that path; commands then run with the application's privileges.
