An Improper Handling of Values vulnerability in the Packet Forwarding Engine (PFE) of Juniper Networks Junos OS Evolved on ACX 7000 Series allows a network-based, unauthenticated attacker to cause a Denial-of-Service (DoS).
If a value is configured for DDoS bandwidth or burst parameters for any protocol in
a queue, all protocols which share the same queue will have
their bandwidth or burst value changed to the new value. If, for example, OSPF was configured with a certain bandwidth value, ISIS would also be limited to this value. So inadvertently either the control plane is open for a high level of specific traffic which was supposed to be limited to a lower value, or the limit for a certain protocol is so low that chances to succeed with a volumetric DoS attack are significantly increased.
This issue affects Junos OS Evolved on ACX 7000 Series:
* All versions before 21.4R3-S7-EVO,
* 22.1 versions before 22.1R3-S6-EVO,
* 22.2 versions before 22.2R3-S3-EVO,
* 22.3 versions before 22.3R3-S3-EVO,
* 22.4 versions before 22.4R3-S2-EVO,
* 23.2 versions before 23.2R2-EVO,
* 23.4
versions
before 23.4R1-S1-EVO, 23.4R2-EVO.
