S-au lansat versiunile corective ale pachetului Samba 4.24.3, 4.23.8 \u0219i 4.22.10, oferind o implementare deschis\u0103 a protocoalelor SMB \u0219i Active Directory. \u00cen noile versiuni au fost remediate 6 vulnerabilit\u0103\u021bi, dintre care dou\u0103 permit unui atacator neautentificat s\u0103 execute cod pe server:<\/p>\n
Vulnerabilitatea este cauzat\u0103 de faptul c\u0103 serviciile RPC SamValidatePasswordChange \u0219i SamValidatePasswordReset transmit loginul \u0219i parola \u00een scriptul definit prin op\u021biunea \u201echeck password script\u201d, f\u0103r\u0103 a escapa caracterele speciale la substitu\u021bia numelui de utilizator prin \u201e%u\u201d. Vulnerabilitatea permite executarea de comenzi shell arbitrare server<\/a> prin indicarea unui nume de utilizator format special. Ca solu\u021bie de protec\u021bie, se recomand\u0103 transmiterea \u00een script a numelui de utilizator nu prin substitu\u021bia \u201e%u\u201d, ci prin variabila de mediu SAMBA_CPS_ACCOUNT_NAME.<\/p>\n De asemenea, \u00een noile versiuni au fost corectate \u0219i alte vulnerabilit\u0103\u021bi, care permit ocolirea verific\u0103rii drepturilor de acces la atributul
