Security readout for executives and security teams
CVE-2018-0023 affects Juniper’s open source JSNAPy automation tool when installed from GitHub before version 1.3.0. Its default configuration and sample files were created world-writable, allowing a local low-privileged user to change automation behavior. This is not remote code execution, but it can undermine trusted network automation workflows. Exposure is likely limited to environments that used GitHub-installed JSNAPy before version 1.3.0 and allowed local unprivileged user access on the host. Package-managed or later installations are not confirmed affected by the supplied sources. Treat this as a targeted hygiene issue for automation hosts, not an internet-wide emergency. Prioritize remediation where JSNAPy runs with access to production network devices or trusted automation workflows. Mitigation focus: Identify JSNAPy installations and confirm whether they came from GitHub.; Upgrade JSNAPy to version 1.3.0 or later where vendor guidance supports it.; Remove world-writable permissions from JSNAPy configuration and sample files..
