Advisory Details

This vulnerability allows remote attackers to execute arbitrary code on vulnerable installations of HP SiteScope. Authentication is not required to exploit this vulnerability.

The specific flaw exists because HP SiteScope allows unauthenticated SOAP calls to be made to the SiteScope service. One of those calls is getSiteScopeConfiguration() which will return the current configuration of the server including the administrator login and password information. A remote attacker could abuse this vulnerability to login to SiteScope with administrative privileges then execute arbitrary code through the underlying functionality.

This vulnerability is being disclosed publicly without a patch in accordance with the ZDI 180 day deadline.

-- Mitigation:
Given the stated purpose of SiteScope, and the nature of the vulnerability, the only salient mitigation strategy is to restrict interaction with the service to trusted machines. Only the clients and servers that have a legitimate procedural relationship with the HP SiteScope service should be permitted to communicate with it. This could be accomplished in a number of ways, most notably with firewall rules/whitelisting. These features are available in the native Windows Firewall, as described in http://technet.microsoft.com/en-us/library/cc725770%28WS.10%29.aspx and numerous other Microsoft Knowledge Base articles.
