SV-77009r1_rule ColdFusion must prevent JavaScript Object Notation (JSON) hijacking of data.

Vulnerability discussion

Information can be either unintentionally or maliciously disclosed if not protected during preparation for transmission. An easy way to protect data during preparation for transmission is to use non-default identifiers for data. An example is for JavaScript Object Notation (JSON) to use a prefix other than the default "JSON" prefix, signifying to an attacker an array of data is following.JSON is a lightweight data-interchange format.

Check content

Within the Administrator Console, navigate to the "Settings" page under the "Server Settings" menu. If the "Prefix serialized JSON with" is unchecked, this is a finding.

Fix text

Navigate to the "Settings" page under the "Server Settings" menu. Check "Prefix serialized JSON with" and select the "Submit Changes" button.

Pro Tips

Lavender hyperlinks in small type off to the right (of CSS class id, if you view the page source) point to globally unique URIs for each document and item. Copy the link location and paste anywhere you need to talk unambiguously about these things.

You can obtain data about documents and items in other formats. Simply provide an HTTP header Accept: text/turtle or Accept: application/rdf+xml.
