Private key disclosed

Summary: PortSwigger Research describes a Burp Scanner finding, issue 0x00600550, in which a valid private key is disclosed within a web application. The text states that disclosure of valid private keys may lead to unauthorized access to any systems that use them for authentication, and advises verifying whether disclosed keys are actually valid and whether their disclosure in the application is appropriate.

What you should know: A private key exposed in an application is a credential to every system that trusts it, so the exposure extends well beyond the page where it was found.
