Detalji

U radu programskog paketa Round Cube Webmail, namijenjenog operacijskom sustavu Fedora 15, uočene su dvije nepravilnosti u radu. Round Cube je višejezični IMAP (eng. Internet Message Access Protocol) klijent s web sučeljem, pisan u PHP programskom jeziku. Prva od ranjivosti nastaje zbog neispravne obrade GET zahtjeva što može imati za posljedicu CSRF napad. Druga ranjivost je posljedica nepravilnosti komponente "modcss.inc" koja može propustiti zlonamjerne zahtjeve napadača. Ispravljeni paketi su dostupni za preuzimanje te se savjetuju korisnicima na uporabu.
