    Summary:

    Details: Jarun nnn through 5.3 contains an OS command injection vulnerability in plugins/togglex that allows attackers to execute commands via crafted filenames. Attackers can place files whose names contain a double quote and shell syntax, which xargs -I splices into an sh -c script, running commands as the user invoking togglex.
