CVE-2019-3712

Status: ModifiedHigh (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.

CVSS

Exploitation probability (EPSS)

EPSS (Exploit Prediction Scoring System, FIRST) estimates how likely a vulnerability is to be exploited in the wild within 30 days. It complements CVSS (impact) and CISA KEV (confirmed exploitation).
