JetBrains WebStorm < 2021.1 Multiple Vulnerabilities

critical Nessus Plugin ID 379717

Synopsis

The integrated development environment installed on the remote host is affected by multiple vulnerabilities.

Description

The version of JetBrains WebStorm installed on the remote host is prior to 2021.1. It is, therefore, affected by multiple vulnerabilities:

 - In JetBrains WebStorm before 2021.1, code execution without user confirmation was possible for untrusted projects. (CVE-2021-31897)

 - In JetBrains WebStorm before 2021.1, HTTP requests were used instead of HTTPS. (CVE-2021-31898)

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

Solution

Upgrade to JetBrains WebStorm version 2021.1 or later.
