ProCheckUp thanks Sun for working with us.
Sun Java System Identity Manager is vulnerable to *unauthenticated* file
retrieval a.k.a. directory traversal within the "ext" parameter
processed by the "/idm/includes/helpServer.jsp" server-side script.
Any files can be retrieved from the target server provided that the
attacker knows its location on the filesystem. No authentication is
required to exploit this vulnerability.
Proof of concept (PoC):
_Due to the severity of this issue, ProCheckUp will keep the PoC private
until all Sun Identity Manager customers are given enough time to update._
Successfully tested on:
Windows Server 2003, Standard
Sun Java System Identity Manager 6.0 (20061212 SP 2)
