When we try to access a web application in the Campaign Classic console where access control is set to Anonymous access, it does not require access credentials when the webPage is previewed through the Preview Tab.
As soon as we enable access control and try to access the web application in Adobe Camping console a web login page is displayed, when the webPage is previewed through the Preview Tab.
Web application access has been restricted and each time such a web application is previewed, the operator’s credentials are asked.
This was introduced from build 8795 wherein on previewing the WebApp with enabling access control, the login credentials are asked.
This change was done in order to enhance security and mitigate the vulnerability. The CTX should be encrypted so that nobody could alter it in this case.
