GHSA-MH68-QF2J-8C5G

Vulnerability from github – Published: 2022-11-02 19:00 – Updated: 2022-11-04 19:01

Details

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".

Severity ?

7.5 (High)
