Technical Analysis
Huawei openBMC contains a privilege assignment flaw (CWE-266) where the function get_user_privilege in route_mapper/account.lua returns the full set of nine privileges for a special_users group that includes the SNMPv1_v2c pseudo-user. As a result, an authenticated SNMP user with low privileges can invoke backend operations as if they had administrative privileges.
Potential Impact
An authenticated SNMP user with low privileges can escalate their privileges to administrative level within openBMC, potentially allowing unauthorized modification or control of backend operations. The CVSS 3.1 base score is 5.4 (medium), indicating limited confidentiality impact but integrity and availability impacts are possible.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. No official fix or patch links are provided in the available data. Until a fix is available, restrict SNMP access to trusted users and networks to reduce exposure.
