CVE-2020-8102Public exploitNetwork attack vector

Remote command execution via unescaped flag injection

Published Jun 22, 2020 · Updated Sep 17, 2024

Improper input validation in Bitdefender Total Security 2020 before 24.0.20.116 allows remote attackers to execute commands via a web page. Bitdefender's HTTPS error page preserves the remote site's origin and exposes session headers, while Safepay passes whitespace-bearing data URLs into a command line without escaping injected flags. Opening an attacker-controlled site in any browser is sufficient; injected commands run with the current user's privileges.
