Summary
Juniper Networks Session Smart Router and Session Smart Conductor are affected before 7.0.5, from 7.1.0 before 7.1.7, and from 7.2.0 before 7.2.3. A path traversal flaw (CWE-22) in ConfigDirector lets an authenticated REST user with low privileges escape the restricted directory. The attacker can read, overwrite, or delete arbitrary certificate and key files on the host filesystem through the certificate and private-key REST API.
