\u00cen serverul ftp ProFTPD a fost identificat\u0103<\/a><\/noindex> o vulnerabilitate periculoas\u0103 (CVE-2019-12815<\/a><\/noindex>), care permite copierea fi\u0219ierelor \u00een cadrul serverului f\u0103r\u0103 a necesita autentificarea prin comenzile «site cpfr» \u0219i «site cpto». Problema a fost clasificat\u0103<\/a><\/noindex> cu un nivel de pericol de 9.8 din 10, deoarece poate fi utilizat\u0103 pentru a organiza executarea de cod pe distan\u021b\u0103 \u00een caz de acces anonim la FTP.<\/p>\n

Vulnerabilitatea provocat\u0103<\/a><\/noindex> o verificare incorect\u0103 a restric\u021biilor de acces pentru citire \u0219i scriere a datelor (Limit READ \u0219i Limit WRITE) \u00een modulul mod_copy, care este utilizat \u00een mod implicit \u0219i inclus \u00een pachetele proftpd pentru majoritatea distribu\u021biilor. Este notabil c\u0103 vulnerabilitatea este o consecin\u021b\u0103 a unei probleme similare care nu a fost complet rezolvat\u0103, identificat\u0103<\/a><\/noindex> \u00een 2015, pentru care acum au fost descoperite noi vectori de atac. Mai mult, problema a fost raportat\u0103 dezvoltatorilor \u00eenc\u0103 din septembrie anul trecut, dar patch-ul a fost preg\u0103tit<\/a><\/noindex> numai acum c\u00e2teva zile.<\/p>\n

Problema se manifest\u0103 \u0219i \u00een ultimele versiuni actuale ProFTPd 1.3.6 \u0219i 1.3.5d. Corec\u021bia este disponibil\u0103 sub form\u0103 de patch<\/a><\/noindex>. Ca o solu\u021bie alternativ\u0103 de protec\u021bie, se recomand\u0103 dezactivarea mod_copy \u00een configura\u021bie. Vulnerabilitatea a fost remediat\u0103 doar \u00een Fedora<\/a><\/noindex> \u0219i r\u0103m\u00e2ne nerezolvat\u0103 \u00een Debian<\/a><\/noindex>, SUSE\/openSUSE<\/a><\/noindex>, Ubuntu<\/a><\/noindex>, FreeBSD<\/a><\/noindex>, EPEL-7<\/a><\/noindex> (ProFTPD nu este disponibil \u00een principalul repository RHEL, iar pachetul din EPEL-6 nu este afectat, deoarece nu include mod_copy).<\/p>\n
