CVE-2021-43589

Status: ModifiedMedium (6.7)—

Dell EMC Unity, Dell EMC UnityVSA and Dell EMC Unity XT versions prior to 5.1.2.0.5.007 contain an operating system (OS) command injection Vulnerability. A locally authenticated user with high privileges may potentially exploit this vulnerability, leading to the execution of arbitrary OS commands on the Unity underlying OS, with the privileges of the vulnerable application. Exploitation may lead to an elevation of privilege.

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).
