Hawt Hawtio through 2.5.0 is vulnerable to SSRF, allowing a remote attacker to trigger an HTTP request from an affected server to an arbitrary host via the initial /proxy/ substring of a URI.
It was discovered that the hawtio servlet 1.4 uses a single HttpClient instance to proxy requests with a persistent cookie store (cookies are stored locally and are not passed between the client and the end URL) which means all clients using that proxy are sharing the same cookies.
hawtio before versions 2.0-beta-1, 2.0-beta-2 2.0-m1, 2.0-m2, 2.0-m3, and 1.5 is vulnerable to a path traversal that leads to a NullPointerException with a full stacktrace. An attacker could use this flaw to gather undisclosed information from within hawtio's root.
