Burp Suite has reported about use of Permanent or persistent cookies on client machine. Should we stop using them? What are the alternatives available?

Hi Sai, Thanks for getting in touch. Could you please include a screenshot of the issue as I'm not quite sure which issue you mean.

Thanks Paul, Please find the issue description below: Description: Sensitive session information such as user credentials or session tokens are stored in a permanent cookie on the client's computer. Permanent (Persistent) cookies are data that a web site presents to the client's web browser, tagged with an expiration date that typically results in the client browser persisting the cookie on local storage (e.g., the hard disk). This data will remain onthe user's system and can be accessed by the site the next time the user browses the site, even across browser sessions.Sensitive information stored in persistent cookies may be leaked to unauthorized users. If the system is shared between multiple usersor a remote attacker manages to install malware on the system, an attacker may be able to access the stored cookie and obtain access to its information. The impact to the user and the application will vary depending on the type of data stored in the persistent cookie: An attacker who gains access to sensitive session information such as user credentials and session tokens may gain access to the victim's session and impersonate that user in the application Leaking personally identifiable information about the victim may lead to identity theft Note:During the assessment, Cigital observed that the application set the few cookies,which contain sensitive information like Username. Note: This finding is systemic throughout the application. Steps To Reproduce: 1. Configure your browser to use a proxy tool such as Burp Suite. 2. Log in to the application. 3. Observe the application response in Burp history.

This issue is by generated Cigital. This isn't produced by Burp Suite. It doesn't seem that they are suggesting that this is a Burp Suite issue. They are suggesting you use a proxy tool (such as Burp Suite) to reproduce the issue.

No they have used Burp Suite only and in the response the cookie contains sensitive information like Username and Expires attribute. Is there any similar issue reported by Burp Suite which talks about disclosure of sensitive information and expiry date by cookies?
