ZDI-11-237: CA Total Defense Suite Gateway Security Malformed HTTP Packet Remote Code Execution Vulnerability http://www.zerodayinitiative.com/advisories/ZDI-11-237 July 20, 2011 -- CVE ID: CVE-2011-2667 -- CVSS: 10, (AV:N/AC:L/Au:N/C:C/I:C/A:C) -- Affected Vendors: CA -- Affected Products: CA Total Defense Suite -- TippingPoint(TM) IPS Customer Protection: TippingPoint IPS customers have been protected against this vulnerability by Digital Vaccine protection filter ID 11478. 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 CA Total Defense Suite r12. Authentication is not required to exploit this vulnerability. The specific flaw exists within the Icihttp.exe module (CA Gateway Security for HTTP), which responds to incoming HTTP requests on port 8080. Due to a flawed copy-loop algorithm in the URL parsing routine, it is possible for a remote unauthenticated user to cause an exploitable heap corruption condition. This could result in the execution of arbitrary code under the context of the Gateway Security service. -- Vendor Response: CA states: CA20110720-01: Security Notice for CA Gateway Security and Total Defense https://support.ca.com/irj/portal/anonymous/phpsupcontent?contentID=%7b5E404992-6B58-4C44-A29D-027D05B6285D%7d -- Disclosure Timeline: 2011-01-21 - Vulnerability reported to vendor 2011-07-20 - Coordinated public release of advisory -- 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.
