Beskrivelse:
Der er rapporteret en sårbarhed i Drupal, som kan udnyttes af ondsindede personer til at kompromittere et sårbart system.

Sårbarheden skyldes en inputvalideringsfejl under håndteringen af kommentar-previews (suppleret i parameteren "comment" i Drupal 5.x eller parameteren "edit[comment]" i Drupal 4.x) og kan udnyttes til at eksekvere vilkårlig kode.

Succesfuld udnyttelse forudsætter "post comments" rettigheder og tilgang til flere input-filtre (ikke standard-indstilling).

Sårbarheden er rapporteret i Drupal 4.7.x tidligere end version 4.7.6 og Drupal 5.x tidligere end 5.1.

Løsning:
Installér patches, eller opdatér til version 4.7.6 eller 5.1.
