Vulnerabilità: CVE-2020-27216

Nelle versioni Eclipse Jetty 1.0 attraverso 9.4.32.v20200930, 10.0.0.alpha1 attraverso 10.0.0.beta2, e 11.0.0.alpha1 attraverso 11.0.0.beta2O, su Unix come i sistemi, directory temporanea del sistema è condiviso tra tutti i utenti su quel sistema. Un utente collocato può osservare il processo di creazione di una sottodirectory temporanea nella directory temporanea condivisa e gara per completare la creazione della directory temporanea. Se l’attaccante vince la gara allora dovranno leggere e permesso di scrittura alla sottodirectory utilizzato per applicazioni web disimballare, comprese le loro file jar WEB-INF / lib e file JSP. Se un codice viene mai eseguito da questa directory temporanea, questo può portare a una vulnerabilità di scalata di privilegi locali.
