Privilege Escalation in openUBMC via SNMP Authentication

Publication date: 2026-10-13

Last updated on: 2026-10-13

Assigner: runZero

Description
openUBMC assigns the full privilege set to pseudo-identities representing SNMP callers. An authenticated, but low-privilege, SNMP user can therefore invoke mapped backend operations as an administrative identity. In `route_mapper/account.lua`, `get_user_privilege` returns the complete nine-privilege set for a `special_users` group that includes the `SNMPv1_v2c` pseudo-user.

Executive Summary

This vulnerability in openUBMC allows an authenticated low-privilege SNMP user to gain full administrative privileges. The system incorrectly assigns full privilege sets to pseudo-identities like SNMP callers, enabling unauthorized access to backend operations.

Impact Analysis

An attacker with low privileges could escalate access to perform administrative actions, potentially compromising system integrity, confidentiality, or availability. This could lead to unauthorized changes, data breaches, or service disruptions.

Compliance Impact

This vulnerability could violate compliance requirements by enabling unauthorized access to sensitive data or systems. GDPR and HIPAA mandate strict access controls; such privilege escalation risks non-compliance, potential fines, and reputational damage.

Mitigation Strategies

Review and restrict privileges for SNMP users, especially those in special_users groups. Remove the special_users group from SNMP pseudo-identities or limit their assigned privileges to only necessary operations.
