Learn more about Junos →⚠️ Risk & Real-World Impact
Worst Case
Tenant administrators could disrupt all tenant traffic, cause service outages, and enable unauthorized traffic interception between tenants, potentially leading to data breaches across multiple organizations.
Likely Case
Accidental misconfiguration by tenant administrators causing traffic routing issues, service degradation, and unintended cross-tenant communication.
If Mitigated
Limited to tenant administrators making configuration errors within their scope, with proper monitoring detecting unusual traffic patterns.
🎯 Exploit Status
Requires tenant administrator privileges. Exploitation likely accidental through misconfiguration rather than malicious intent.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Multiple fixed versions per release: 19.2R1-S6, 19.2R3-S2, 19.3R3-S2, 19.4R2-S4, 19.4R3-S2, 20.1R2, 20.1R3, 20.2R2-S1, 20.2R3, 20.3R1-S2, 20.3R2, 20.4R1, 20.4R2
