CVE-2020-1688
Exploitation of this vulnerability may allow an attacker to decrypt the communications between the Juniper device and the authenticator service.
Does this matter?
Lower severity and a low EPSS score (0.32%). Track it; it rarely justifies an emergency change on its own.
Description
On Juniper Networks SRX Series and NFX Series, a local authenticated user with access to the shell may obtain the Web API service private key that is used to provide encrypted communication between the Juniper device and the authenticator services. Exploitation of this vulnerability may allow an attacker to decrypt the communications between the Juniper device and the authenticator service. This Web API service is used for authentication services such as the Juniper Identity Management Service, used to obtain user identity for Integrated User Firewall feature, or the integrated ClearPass authentication and enforcement feature.
