Descriptions

An out-of-bounds read in the rewrite function at /modules/caddyhttp/rewrite/rewrite.go in Caddy v2.5.1 allows attackers to cause a Denial of Service (DoS) via a crafted URI. Note: This has been disputed as a bug, not a security vulnerability, in the Caddy web server that emerged when an administrator's bad configuration containing a malformed request URI caused the server to return an empty reply instead of a valid HTTP response to the client.

Una lectura fuera de límites en la función rewrite en el archivo /modules/caddyhttp/rewrite/rewrite.go en Caddy v2.5.1 permite a atacantes causar una denegación de servicio (DoS) por medio de un URI diseñado
