Nella libreria ssh, parte del toolkit Erlang\/OTP, \u00e8 stata identificata una vulnerabilit\u00e0 (CVE-2025-32433) che consente l'esecuzione remota di codice su un server SSH creato con la libreria vulnerabile, senza necessit\u00e0 di autenticazione. Il problema \u00e8 stato classificato con un livello di gravit\u00e0 critico (10 su 10). <\/p>\n

Un ricercatore di sicurezza ha gi\u00e0 sviluppato un exploit funzionante per l'esecuzione di codice su server SSH vulnerabili. Nota interessante, secondo il ricercatore, il codice \u00e8 stato creato utilizzando assistenti AI come GPT-4, Cursor e Sonnet, analizzando le modifiche apportate per risolvere la vulnerabilit\u00e0, comprensivo di un test per verificare la risoluzione del problema. <\/p>\n
