Nel framework web Apache Struts, utilizzato per creare applicazioni web in Java seguendo la paradigma MVC (Model-View-Controller), \u00e8 stata scoperta una vulnerabilit\u00e0 (CVE-2024-53677). La vulnerabilit\u00e0 consente a un attaccante esterno di scrivere un file in un luogo a piacere nel file system del server inviando una richiesta HTTP appositamente formata. Il problema riguarda le versioni dalla 2.0.0 alla 2.3.37, dalla 2.5.0 alla 2.5.33 e dalla 6.0.0 alla 6.3.0.2, e si manifesta nelle applicazioni che utilizzano il componente FileUploadInterceptor per il caricamento di file sul server. <\/p>\n

La vulnerabilit\u00e0 \u00e8 causata dall'assenza di un'adeguata verifica dei parametri inviati durante il caricamento dei file. Se si ha accesso alle funzioni di caricamento dei file nell'interfaccia web basata su Apache Struts, un attaccante pu\u00f2 specificare un valore del tipo \u00ab..\\\/..\\\/..\\\/..\\\/..\\\/webapps\\\/ROOT\u00bb e ottenere che il file venga salvato al di fuori della directory destinata ai dati caricati (prototipo di exploit). Ottenendo la possibilit\u00e0 di scrivere file in parti arbitrarie del filesystem, si possono eseguire comandi propri. server<\/a>, sovrascrivendo script o file di configurazione, a seconda dei diritti dell'utente con cui viene eseguita l'applicazione web. Se l'applicazione web \u00e8 eseguita all'interno di un contenitore Apache Tomcat avviato con diritti di root, l'attaccante pu\u00f2 ottenere accesso privilegiato al sistema. <\/p>\n

Le vulnerabilit\u00e0 in Apache Struts sono significative poich\u00e9 questo framework \u00e8 ampiamente utilizzato nei sistemi aziendali accessibili tramite web. Secondo le statistiche di RedMonk, il framework Apache Struts \u00e8 stato utilizzato nelle applicazioni web dal 65% delle aziende nella lista Fortune 100. Nel 2017, un attacco al sistema informatico della societ\u00e0 Equifax, che utilizzava una versione vulnerabile di Apache Struts, ha portato alla fuoriuscita di dati personali di 143 milioni di cittadini statunitensi.
