Command execution via shell-interpreted reset destination
Published Feb 18, 2021 · Updated Sep 17, 2024
Command injection in omrilotan async-git before 1.13.2 allows attackers to execute shell commands through a crafted reset destination. The reset function interpolates the destination into a command string passed to async-execute, allowing shell backticks in that value to launch a second command. Exploitation requires a consuming application to pass attacker-controlled input to git.reset, and injected commands run with the Node.js process privileges.
