CVE-2010-4053: Stack-based buffer overflow in an unspecified logging function in oninit.exe in IBM Informix Dynamic Server...

Security readout for executives and security teams

This CVE affects older IBM Informix Dynamic Server releases. An authenticated remote user could trigger a stack buffer overflow and potentially run arbitrary code on the database server. Business urgency depends on whether legacy IDS 11.10 or 11.50 is still present and reachable by untrusted or broadly provisioned accounts. Exposure is most likely in legacy environments still running IBM IDS 11.10 or 11.50 below the fixed levels. The attacker must already authenticate remotely, so risk is higher where database access is widely granted, internet-reachable, or exposed through partner, application, or shared service accounts. Prioritize if legacy Informix supports important business systems or is reachable by many users. This is not a broad unauthenticated internet issue from the available evidence, but arbitrary code execution on a database server can be business-critical when exposure exists. Mitigation focus: Inventory IBM Informix Dynamic Server instances and identify any IDS 11.10 or 11.50 deployments.; Upgrade IDS 11.10 to 11.10.xC2W2 or later where applicable.; Upgrade IDS 11.50 to 11.50.xC1 or later where applicable..
