We are working on a special sprint enhancing security The following security enhancements were added to prevent software vulnerabilities in all the OMK Applications. 

...

• opCharts 4.2.5
• opConfig 4.2.4
• opEvents 4.0.2
• opHA 3.3.1
• opReports 4.2.2

Randomize Secrets

New setup A new tool to randomize the secrets from the command line. This tool will randomize omkd_secrets tokens in OMK and also, NMIS auth_web_key when it matches some of the OMK tokens (Usually set to configure SSO for Opmantek Applications). The omkd_secrets token is used for Single-Sign-On, see SSO for Firstwave Applications. 

This tool is also called by the installer and fixed CVE-2021-38551.

...

/usr/local/omk/bin/opcommon-cli.exe act=secrets_randomise [force=true] [length=N]

Where:

• • force=true will change the token even if this is not the default (Like =~ change_me)
  • length=N will force the token length to N (32 by default)

...

Cookie	Support	Behaviour
HttpOnly	By default	The cookies are not going to be accesible accessible from the JavaScript API.
secure	Should be enabled by setting the configuration item "auth_secure_cookie" => "true" in opCommon.json.	This cookie could be sent just in a request ciphered over https protocol. That's the reason why it is not set by default.
SameSite set to Strict	Supported since the following versions: OAE Open-AudIT 4.34.0 opAddress 2.1.0 opCharts 4.3.0 opConfig 4.3.0 opEvents 4.1.0 opHA 3.4 opReports 4.3.0	The cookie set to strict means that the browser only sends the cookie if the request was made in the website that originally established the cookie.

...

Content

...

Security Policy

The Security Content Policy often referred to as Content Security Policy , is a http HTTP response header that restricts how helps you restrict which resources (JavaScript, CSS, Images, etc.) are loaded from the allowed sites. It will help This helps to mitigate some attacks of Cross Site Scripting (XSS) and data injection. 

...

The default values can be overwritten by setting the configuration item security_content_policy under the authentication section in the configuration file, opCommon.json.

The default values include included in the source code are:

"connect-src 'self' opmantek.com community.opmantek.com services.opmantek.com ws: wss: maps.googleapis.com maps.google.com maps.gstatic.com; font-src 'self' fonts.gstatic.com; form-action 'self'; frame-ancestors 'none'; frame-src 'none'; manifest-src 'none'; media-src 'none'; object-src 'none'; prefetch-src 'self'; script-src 'self' 'unsafe-eval' 'unsafe-inline' maps.googleapis.com maps.google.com; style-src 'self' fonts.googleapis.com 'unsafe-inline'; worker-src 'self';"

...

"connect-src 'self' opmantek.com community.opmantek.com services.opmantek.com maps.googleapis.com ws: wss: maps.google.com maps.gstatic.com; font-src 'self' fonts.gstatic.com; form-action 'self'; frame-ancestors 'none'; frame-src 'none'; img-src 'self' data: maps.google.com maps.gstatic.com; manifest-src 'none'; media-src 'none'; object-src 'none'; prefetch-src 'self'; script-src 'self' 'unsafe-eval' 'unsafe-inline' maps.googleapis.com maps.google.com; style-src 'self' fonts.googleapis.com 'unsafe-inline'; worker-src 'self';"

Depending on what you need to achieve, you will need to update your configuration to include some or all of the default options as well as options specific to your environment.

For example, if you were going want to include one of the Opmantek FirstWave applications in an iFrame, you would need to include directives for frame-ancestors and frame-src, e.g.

frame-ancestors https://*.yourdomain.com
frame-src https://*.yourdomain.com

The total final configuration would be something like the following:

The below is formatted for easy reading. In the JSON file no line breaks should be used.

Note that you should replace *.yourdomain.com with an appropriate domain for your use-case.

"security_content_policy": "connect-src 'self' opmantek.com community.opmantek.com services.opmantek.com ws: wss: maps.googleapis.com maps.google.com maps.gstatic.com;
    font-src 'self' fonts.gstatic.com; 
    form-action 'self';
    frame-ancestors https://*.yourdomain.com;
    frame-src https://*.yourdomain.com;
    manifest-src 'none';
    media-src 'none';
    object-src 'none';
  prefetch-src 'self'; script-src 'self' 'unsafe-eval' 'unsafe-inline' maps.googleapis.com maps.google.com;
    style-src 'self' fonts.googleapis.com 'unsafe-inline';
    worker-src 'self';"
