CVE-2022-22186 is a medium-severity vulnerability rated 6.5/10 on the CVSS scale. Due to an Improper Initialization vulnerability in Juniper Networks Junos OS on EX4650 devices, packets received on the management interface (em0) but not destined to the device, may be improperly forwarded to an egress interface, instead of being discarded. Such traffic being sent by a client may appear genuine, but is non-standard in nature and should be considered as potentially malicious. EPSS estimates a 0.60% chance of exploitation in the next 30 days.
