CVE-2024-27301Public exploit

Root code execution via inherited zsh environment

Published Mar 14, 2024 · Updated Aug 2, 2024

Local privilege escalation in Root3 Support App 2.3.1 through 2.5.1 Rev 1 allows local users to execute arbitrary code as root. The postinstall script invokes zsh without --no-rcs under sudo while retaining the invoking user's HOME, so zsh loads commands from $HOME/.zshenv. A local user must modify that account's .zshenv and wait for an administrator to run the package installer; the commands then receive root privileges.
