Nel framework web Apache Struts, utilizzato per creare applicazioni web in Java seguendo la paradigma MVC (Model-View-Controller), \u00e8 stata rilevata una vulnerabilit\u00e0 (CVE-2024-53677). Questa vulnerabilit\u00e0 consente a un potenziale attaccante di scrivere un file in un luogo arbitrario del filesystem sul server tramite l'invio di una richiesta HTTP appositamente formattata. 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 dei file sul server. <\/p>\n

La vulnerabilit\u00e0 \u00e8 causata dall'assenza di un adeguato controllo dei parametri passati durante il caricamento dei file. Se si ha accesso alle funzioni di caricamento dei file nell'interfaccia web implementata su Apache Struts, un attaccante pu\u00f2 specificare un valore come \u00ab..\/..\/..\/..\/..\/webapps\/ROOT\u00bb e ottenere la conservazione del file al di fuori della directory destinata ai dati caricati (prototipo di exploit). Ottenendo la possibilit\u00e0 di scrivere file in parti arbitrarie del filesystem, \u00e8 possibile organizzare l'esecuzione dei propri comandi su server<\/a>, riscrivendo script o file di configurazione, a condizione che i diritti dell'utente con cui viene eseguita l'applicazione web lo consentano. Se l'applicazione web viene eseguita in un contenitore Apache Tomcat avviato con privilegi 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 via web. Secondo le statistiche di RedMonk, il framework Apache Struts \u00e8 stato utilizzato nel 65% delle applicazioni web delle aziende incluse nella lista Fortune 100. Nel 2017, un attacco al sistema informativo della compagnia Equifax, che utilizzava una versione vulnerabile di Apache Struts, ha portato alla fuga di dati personali di 143 milioni di cittadini statunitensi.
