H3C LS-5500-28C-PWR-SI 24-Port Switch P/N 0235A05H Equipment H3C-User snmp

The MIBs h3c-user.mib and hh3c-user.mib, for the purpose of this document, will be referred to as (h)h3c-user.mib. This MIB defines the internal table and objects to “Manage configuration and Monitor running state for userlog feature.”

This means there are some cool objects with data in this MIB penetration testers or malicious actors would want to get their dirty little hands on. Most objects are only accessible with the read/write community string.

In the revision history of (h)h3c-user.mib, version 2.0 modified the MAX-ACCESS from read-only to read-create the following objects within the (h)h3cUserInfoEntry sequence:

The purpose of these objects are to provide the locally configured users to those with a valid SNMP community. After the change only those with the read-write community string should have access, however this was not the case and the code still retained the earlier access of read-only.

So if you have the SNMP public community string then you have the ability to view these entries."_
