ZDI-08-011: IBM Informix Dynamic Server DBPATH Buffer Overflow Vulnerability http://www.zerodayinitiative.com/advisories/ZDI-08-011 March 13, 2008

-- CVE ID: CVE-2008-0727

-- Affected Vendors: IBM

-- Affected Products: IBM Informix

-- TippingPoint(TM) IPS Customer Protection: TippingPoint IPS customers have been protected against this vulnerability by Digital Vaccine protection filter ID 5723. For further product information on the TippingPoint IPS, visit:

-- 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:
