It is recommended that administrators restrict access to 23472/tcp to trusted hosts only. HP are working on a fix which may be available soon. - --------------------------BEGIN INCLUDED TEXT-------------------- - -----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 ZDI-12-016 : (0Day) HP Diagnostics Server magentservice.exe Remote Code Execution Vulnerability http://www.zerodayinitiative.com/advisories/ZDI-12-016 January 12, 2012 - - -- CVE ID: CVE-2011-4789 - - -- CVSS: 10, AV:N/AC:L/Au:N/C:C/I:C/A:C - - -- Affected Vendors: Hewlett-Packard - - -- Affected Products: Hewlett-Packard Diagnostics Server - - -- Vulnerability Details: This vulnerability allows remote attackers to execute arbitrary code on vulnerable installations of HP Diagnostics server. Authentication is not required to exploit this vulnerability. The specific flaw exists within the way the HP Diagnostics server handles incomming packets with 0x00000000 as the first 32-bit value. The magentservice.exe process listens on port 23472 by default. It will eventually take that first dword, decrease it by one and use it as a size value to copy data into a stack buffer. The resulting stack-based buffer overflow can result in remote code execution under the system user. - - -- Vendor Response: - - -- Mitigation: HP states that a patch for this vulnerability will be made available to the public "soon." Until that time, it is recommended that administrators of Diagnostics Server enabled systems restrict access to port 23472 to trusted hosts only. - - -- Disclosure Timeline: 2011-06-03 - Vulnerability reported to vendor 2012-01-12 - 0Day advisory released in accordance with the ZDI 180 day deadline policy - - -- Credit: This vulnerability was discovered by: * AbdulAziz Hariri - - -- 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.
