CVE-2024-47505Network attack vector

FPC hangs via evo-pfemand GUID exhaustion

Published Oct 11, 2024 · Updated Oct 11, 2024

Resource exhaustion in evo-pfemand in Juniper Networks Junos OS Evolved allows remote authenticated users to hang FPCs. Specific SNMP GET operations or low-privileged CLI commands leak GUID resources until the finite GUID space is exhausted. Access to an authenticated management interface is required, and affected FPCs remain hung until they are manually restarted.
