CVE-2019-3712

Estado: ModificadaAlta (8.8)—

Dell WES Wyse Device Agent versions prior to 14.1.2.9 and Dell Wyse ThinLinux HAgent versions prior to 5.4.55 00.10 contain a buffer overflow vulnerability. An unauthenticated attacker may potentially exploit this vulnerability to execute arbitrary code on the system with privileges of the FTP client by sending specially crafted input data to the affected system. The FTP code that contained the vulnerability has been removed.
