CVE-2022-41716

CVE-2022-41716 · Unsanitized NUL in environment variables on Windows in syscall and os/exec

This page contains facts from public vulnerability sources. Check the original advisory before updating.

Due to unsanitized NUL values, attackers may be able to maliciously set environment variables on Windows. In syscall.StartProcess and os/exec.Cmd, invalid environment variable values containing NUL values are not properly checked for. A malicious environment variable value can exploit this behavior to set a value for a different environment variable. For example, the environment variable string "A=B\x00C=D" sets the variables "A=B" and "C=D".
