Il problema \u00e8 causato dall'assenza di un'adeguata verifica del nome host, in cui era consentita la codifica dei caratteri nel formato %xx (URL Encoding). Un attaccante poteva utilizzare la codifica percentuale per aggiungere nel nome host sequenze di escape che manipolano l'output del terminale.\n<p>In questo modo, \u00e8 possibile sostituire il testo del messaggio di autenticazione e creare nell'utente la sensazione di rivolgersi a un altro repository. Pertanto, quando l'utente tentava di accedere al repository dell'attaccante, inseriva le credenziali di un altro host. L'attacco pu\u00f2 essere effettuato durante l'esecuzione del cloning ricorsivo dei sottomoduli con il comando \"git clone \u2014recurse-submodules\", in cui uno dei sottomoduli potrebbe richiedere la password di un altro host, ma l'input sarebbe inviato all'host con il repository dell'attaccante.      <\/p>\n<li class=\"l\"> CVE-2024-52006 \u2014 nella realizzazione del protocollo \"credential helper\", utilizzato per trasmettere le credenziali quando si accede a repository con accesso limitato, \u00e8 stata identificata una vulnerabilit\u00e0 che consente di inserire un carattere di ritorno a capo tramite l'indicazione di un URL opportunamente formattato. Poich\u00e9 il protocollo manipola i dati riga per riga, l'aggiunta di un ritorno a capo pu\u00f2 essere utilizzata per separare i blocchi di dati e organizzare la trasmissione della password non verso l'host corretto. <a class=\"wpil_keyword_link\" href=\"https:\/\/prohoster.info\/it\/server\/\"   title=\"server\" data-wpil-keyword-link=\"linked\">server<\/a>. La possibilit\u00e0 di effettuare un attacco dipende dall'interpretazione del carattere di ritorno a capo come delimitatore di riga nelle diverse implementazioni del protocollo \"credential helper\". Ad esempio, \u00e8 vulnerabile il Git Credential Manager, scritto in C#\/ .NET.    <\/ul>\n<p>Si raccomanda agli utenti che non possono aggiornare Git di astenersi dal rivolgersi a repository esterni non verificati utilizzando il comando \"git clone\" con l'opzione \"\u2014recurse-submodules\", e di escludere l'uso di gestori delle credenziali durante il cloning di repository pubblici. Oltre a Git, le correzioni per bloccare queste vulnerabilit\u00e0 sono state rilasciate per GitHub Desktop (CVE-2025-23040), Git LFS (CVE-2024-53263) e Git Credential Manager (CVE-2024-50338).<br
