CVE-2021-42372Public exploitNetwork attack vector

Authenticated command execution via SNMP community injection

Published Nov 8, 2021 · Updated Aug 4, 2024

OS command injection in XoruX LPAR2RRD and STOR2RRD before 7.30 allows remote authenticated users to execute shell commands. The HW Events configuration passes the SNMP community string into a shell command without neutralizing command metacharacters. Access to the authenticated Alerting Options interface is required, and injected commands run with the service account's privileges.
