Hi Everyone,

I’ve little trouble understanding how i can allow this request.

Requests are getting blocked at WAF end due to “Malformed JSON data” violation (Illegal character encountered - json syntax error -" / ")

Can i allow / (forward slash) character to provide exception for this violation & keep malformed json data blocking setting as it is. and how can i achieve this.

Hi Jack3,

  • Create a new JSON profile.
    Security > Application Security > Content Profiles > JSON Profiles > Create New JSON Profile…
  • Edit the properties according to the JSON profile used by default.
  • Disable Parse Parameters option.
  • Allow forward slash (/) character in the Value Meta Characters tab.
  • Select newly created json profile from the “Header-Based Content Profiles” tab of the matching url.
    Security > Application Security > URLs > Allowed URLs > Allowed HTTP URLs > [URL] > Header-Based Content Profiles
    • Delete the line containing *json*.
    • Add new line:
      • Request Header Name: Content-Type
      • Request Header Value: *json*
      • Request Body Handling: JSON
      • Profile Name: [New json profile]
