ZDI-11-150: HP Data Protector Backup Client Service omniiaputil Message Processing Remote Code Execution Vulnerability http://www.zerodayinitiative.com/advisories/ZDI-11-150 April 29, 2011 -- CVE ID: CVE-2011-1734 -- CVSS: 10, (AV:N/AC:L/Au:N/C:C/I:C/A:C) -- Affected Vendors: Hewlett-Packard -- Affected Products: Hewlett-Packard Data Protector -- TippingPoint(TM) IPS Customer Protection: TippingPoint IPS customers have been protected against this vulnerability by Digital Vaccine protection filter ID 11129. 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 OpenView Data Protector. Authentication is not required to exploit this vulnerability. This specific flaw exists in the Backup Client Service (OmniInet.exe). The Backup Client Service listens on TCP port 5555 for communications between systems in the cell. The process has insufficient bounds checking on user-supplied data in a fixed-length buffer on the stack. Remote, unauthenticated attackers can exploit this vulnerability by sending malformed omniiaputil message packets to the target, which could ultimately lead to arbitrary code execution under the context of the SYSTEM user. -- Vendor Response: Hewlett-Packard has issued an update to correct this vulnerability.
