ZDI-12-174 : (0Day) HP SiteScope UploadFilesHandler Remote Code Execution Vulnerability http://www.zerodayinitiative.com/advisories/ZDI-12-174 August 29, 2012 -- CVE ID: -- CVSS: 10, AV:N/AC:L/Au:N/C:C/I:C/A:C -- Affected Vendors: Hewlett-Packard -- Affected Products: Hewlett-Packard SiteScope -- TippingPoint(TM) IPS Customer Protection: TippingPoint IPS customers have been protected against this vulnerability by Digital Vaccine protection filter ID 12485. For further product information on the TippingPoint IPS, visit: http://www.tippingpoint.com -- Vulnerability 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 is a directory traversal in the UploadFilesHandler url that allows you to upload files to the server into a directory on the server that allows for scripting. This vulnerability could lead to remote code execution under the context of the current process. -- Vendor Response: -- 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. -- Disclosure Timeline: 2011-12-22 - Vulnerability reported to vendor 2012-08-29 - 0Day advisory released in accordance with the ZDI 180 day deadline policy -- Credit: This vulnerability was discovered by: * Andrea Micalizzi aka rgod -- About the Zero Day Initiative (ZDI): Established by TippingPoint, The Zero Day Initiative (ZDI) represents a best-of-breed model for rewarding security researchers for responsibly disclosing discovered vulnerabilities.
