CVE-2020-5364Network attack vector

Sensitive data exposure via default SNMPv2 community string

Published May 20, 2020 · Updated Sep 16, 2024

Information exposure in Dell EMC Isilon OneFS 8.2.2 and earlier allows remote attackers to read sensitive cluster data via SNMPv2. The SNMPv2 service accepts a pre-configured community string enabled by default and exposes read-only details about many cluster components without authentication. An attacker able to reach the SNMP interface can obtain sensitive information that may support further access, without documented ability to modify data or disrupt service.
