Vulnerability Title
Apache Neethi: Unrestricted HTTP Redirect Following in Policy References
Source: NVD (National Vulnerability Database)
Vulnerability Description
Apache Neethi does not impose any restrictions on URIs when manually fetching remote policy references through the PolicyReference API. When an application explicitly calls the API to retrieve a policy from a remote URI, an outbound request is made for arbitrary protocols and internal IP adddresses. From 3.2.2, only http or https URIs are allowed, and link-local/multicast/any-local addresses are forbidden. Users are recommended to upgrade to version 3.2.2, which fixes this issue.
