ZDI-08-034: HP StorageWorks Storage Mirroring Authentication Processing Stack Overflow Vulnerability http://www.zerodayinitiative.com/advisories/ZDI-08-034 June 4, 2008 -- CVE ID: CVE-2008-1661 -- Affected Vendors: Hewlett-Packard -- Affected Products: Hewlett-Packard StorageWorks -- TippingPoint(TM) IPS Customer Protection: TippingPoint IPS customers have been protected against this vulnerability by Digital Vaccine protection filter ID 6051. 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 Hewlett Packard StorageWorks Storage Mirroring. Authentication is not required to exploit this vulnerability. The specific flaw exists in the DoubleTake.exe process bound by default on TCP ports 1100, 1106 and UDP port 1105. During the handling of an encoded authentication request, the process copies the user-supplied login information into a fixed length stack buffer. Sending at least 256 bytes will trigger a stack based buffer overflow due to a vulnerable processing loop. Exploitation of this issue can result in arbitrary code execution. -- Vendor Response: Hewlett-Packard states: To resolve this vulnerability download HP StorageWorks Storage Mirroring software v4.5 Service Pack 2 (SP2) from Double-Take at the following URL: http://www.doubletake.com/products/double-take/default.aspx -- Disclosure Timeline: 2007-05-22 - Vulnerability reported to vendor 2008-06-04 - Coordinated public release of advisory -- Credit: This vulnerability was discovered by: * Titon of BastardLabs -- 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.
