April 11, 2019

Analysis Summary

CVE-2019-0036

When configuring a stateless firewall filter in Junos OS, terms named using the format “internal-n” (e.g. “internal-1”, “internal-2”, etc.) are silently ignored. No warning is issued during configuration, and the config is committed without error, but the filter criteria will match all packets leading to unexpected results.
