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 systems with vulnerable installations of IBM's Informix Dynamic Server. User interaction is not required to exploit this vulnerability. Authentication is required in that an attacker must have database connection priviliges. The specific flaw exists in the oninit.exe process that listens by default on TCP port 1526. During authentication, the process does not validate the length of the DBPATH variable. An attacker can provide a overly long variable name and overflow a global buffer, overwriting function pointers leading to arbitrary code execution. - -- Vendor Response: IBM has issued an update to correct this vulnerability. More details can be found at: http://www-1.ibm.com/support/docview.wss?uid=swg1IC55208 http://www-1.ibm.com/support/docview.wss?uid=swg1IC55207 - -- Disclosure Timeline: 2007-11-07 - Vulnerability reported to vendor 2008-03-13 - Coordinated public release of advisory - -- Credit: This vulnerability was discovered by: * Anonymous - -- 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. Researchers interested in getting paid for their security research through the ZDI can find more information and sign-up at: http://www.zerodayinitiative.com The ZDI is unique in how the acquired vulnerability information is used. TippingPoint does not re-sell the vulnerability details or any exploit code. Instead, upon notifying the affected product vendor, TippingPoint provides its customers with zero day protection through its intrusion prevention technology. Explicit details regarding the specifics of the vulnerability are not exposed to any parties until an official vendor patch is publicly available. Furthermore, with the altruistic aim of helping to secure a broader user base, TippingPoint provides this vulnerability information confidentially to security vendors (including competitors) who have a vulnerability protection or mitigation product.
