Description
JSNAPy is an open source python version of Junos Snapshot Administrator developed by Juniper available through github. The default configuration and sample files of JSNAPy automation tool versions prior to 1.3.0 are created world writable. This insecure file and directory permission allows unprivileged local users to alter the files under this directory including inserting operations not intended by the package maintainer, system administrator, or other users. This issue only affects users who downloaded and installed JSNAPy from github.

Remediation
Vendor solution
This issue is resolved in 1.3.0 and subsequent releases. Fixed JSNAPy releases can be downloaded from https://github.com/Juniper/jsnapy/releases.
Upgrading to the fixed release is not sufficient to resolve the issue, modifying file permission after upgrade as described in the workaround section is required. This issue is fixed for fresh/new installation.
