Sono state rilasciate le versioni correttive dei pacchetti Samba 4.24.3, 4.23.8 e 4.22.10, che forniscono un'implementazione open source dei protocolli SMB e Active Directory. Nelle nuove versioni sono state risolte 6 vulnerabilit\u00e0, di cui due consentono a un attaccante remoto non autenticato di eseguire codice sul server:<\/p>\n
La vulnerabilit\u00e0 \u00e8 causata dal fatto che i servizi RPC SamValidatePasswordChange e SamValidatePasswordReset trasmettono il nome utente e la password allo script definito tramite l'impostazione \u00abcheck password script\u00bb senza l'escaping dei caratteri speciali quando viene sostituito il nome utente tramite \u00ab%u\u00bb. La vulnerabilit\u00e0 consente di eseguire comandi shell arbitrari su server<\/a> indicando un nome utente appositamente formattato. Come soluzione alternativa per la protezione, si suggerisce di passare allo script il nome utente non tramite jolly \u00ab%u\u00bb, ma tramite la variabile ambiente SAMBA_CPS_ACCOUNT_NAME.<\/p>\n Inoltre, nelle nuove release sono state corrette diverse altre vulnerabilit\u00e0 che permettevano di bypassare il controllo dei diritti di accesso all'attributo xattr \u00abreparse point\u00bb, riscrivere di nuovo un file utilizzando il modulo vfs WORM (Write-Once, Read Many), installare un certificato tramite HTTP senza verifica e causare un crash. server<\/a> AD DC WINS tramite l'invio di un pacchetto UDP appositamente formato. \u041f\u0440\u0435\u0434\u0441\u0442\u0430\u0432\u043b\u0435\u043d\u044b \u043a\u043e\u0440\u0440\u0435\u043a\u0442\u0438\u0440\u0443\u044e\u0449\u0438\u0435 \u0440\u0435\u043b\u0438\u0437\u044b \u043f\u0430\u043a\u0435\u0442\u0430 Samba 4.24.3, 4.23.8 \u0438 4.22.10, \u043f\u0440\u0435\u0434\u043e\u0441\u0442\u0430\u0432\u043b\u044f\u044e\u0449\u0435\u0433\u043e \u043e\u0442\u043a\u0440\u044b\u0442\u0443\u044e \u0440\u0435\u0430\u043b\u0438\u0437\u0430\u0446\u0438\u044e \u043f\u0440\u043e\u0442\u043e\u043a\u043e\u043b\u043e\u0432 SMB \u0438 Active Directory. \u0412 \u043d\u043e\u0432\u044b\u0445 \u0432\u0435\u0440\u0441\u0438\u044f\u0445 \u0443\u0441\u0442\u0440\u0430\u043d\u0435\u043d\u043e 6 \u0443\u044f\u0437\u0432\u0438\u043c\u043e\u0441\u0442\u0435\u0439, \u0438\u0437 \u043a\u043e\u0442\u043e\u0440\u044b\u0445 \u0434\u0432\u0435 \u043f\u043e\u0437\u0432\u043e\u043b\u044f\u044e\u0442 \u0443\u0434\u0430\u043b\u0451\u043d\u043d\u043e\u043c\u0443 \u043d\u0435\u0430\u0443\u0442\u0435\u043d\u0442\u0438\u0444\u0438\u0446\u0438\u0440\u043e\u0432\u0430\u043d\u043d\u043e\u043c\u0443 \u0430\u0442\u0430\u043a\u0443\u044e\u0449\u0435\u043c\u0443 \u0432\u044b\u043f\u043e\u043b\u043d\u0438\u0442\u044c \u0441\u0432\u043e\u0439 \u043a\u043e\u0434 \u043d\u0430 \u0441\u0435\u0440\u0432\u0435\u0440\u0435: CVE-2026-4408 — \u0443\u044f\u0437\u0432\u0438\u043c\u043e\u0441\u0442\u044c \u0432 \u0440\u0435\u0430\u043b\u0438\u0437\u0430\u0446\u0438\u0438 \u0441\u0435\u0440\u0432\u0435\u0440\u0430 SAMR (Security Account Manager) \u043f\u043e\u0432\u0435\u0440\u0445 DCE\/RPC, \u043f\u0440\u0438\u043c\u0435\u043d\u044f\u0435\u043c\u043e\u0433\u043e \u0434\u043b\u044f \u0443\u043f\u0440\u0430\u0432\u043b\u0435\u043d\u0438\u044f \u0443\u0447\u0451\u0442\u043d\u044b\u043c\u0438 \u0434\u0430\u043d\u043d\u044b\u043c\u0438 \u0438 \u0411\u0414 c […]<\/p>\n","protected":false,"gt_translate_keys":[{"key":"rendered","format":"html"}]},"author":8,"featured_media":0,"comment_status":"open","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[702],"tags":[],"class_list":["post-181775","post","type-post","status-publish","format-standard","hentry","category-novosti-interneta"],"aioseo_notices":[],"aioseo_head":"\n\t\t\n\t\n\t\n\t\n\t\n\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\n","aioseo_head_json":{"title":"\ud83e\udd47Vulnerabilit\u00e0 in Samba che consentono l'esecuzione remota di codice in configurazioni rare | ProHoster","description":"Sono stati rilasciati aggiornamenti correttivi per i pacchetti Samba 4.24.3, 4.23.8 e 4.22.10, che forniscono un'implementazione open source dei protocolli SMB e Active Directory.
