Detailsinfo

A vulnerability was found in greenpau caddy-security (the affected version unknown). It has been classified as problematic. Affected is an unknown part of the component Caddyfile Parser. The manipulation with an unknown input leads to a array index vulnerability. CWE is classifying the issue as CWE-129.
