IBM Informix Dynamic Server 14.10, 12.10.x, and 15.0 IBM Informix oninit sq_sgkprepare RCE via unchecked SQL Interface length field.
AnalysisAI
Remote code execution in IBM Informix Dynamic Server 14.10, 12.10.x, and 15.0 is possible through a stack-based buffer overflow (CWE-121) in the oninit daemon's sq_sgkprepare function, triggered when processing a SQL interface request containing an unchecked length field. An authenticated, network-adjacent attacker with low-privilege SQL credentials can exploit this to achieve full compromise of the database server, resulting in complete confidentiality, integrity, and availability impact. …

Attack ChainAIDerived
Hypothetical attack flow derived from CVE metadata
Vulnerability AssessmentAI
| Exploitation | Exploitation requires an authenticated SQL session with at least low-privilege credentials on the target IBM Informix Dynamic Server instance, consistent with the CVSS PR:L metric. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The CVSS 3.1 score of 8.8 reflects a network-reachable (AV:N), low-complexity (AC:L) attack requiring only low-privilege SQL credentials (PR:L) with no user interaction and full CIA impact - characteristics consistent with a highly dangerous RCE class vulnerability. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | Full exploit scenario with step-by-step reproduction available after sign-in. |
| Remediation | Apply the vendor-released patch for IBM Informix Dynamic Server as detailed in IBM Security Advisory 7283143 at https://www.ibm.com/support/pages/node/7283143, which covers the 12.10.x, 14.10, and 15.0 release lines. … Detailed patch versions, workarounds, and compensating controls in full report. |
Recommended ActionAI
Within 24 hours, inventory all systems running IBM Informix Dynamic Server versions 12.10.x, 14.10, or 15.0 and identify those with exposed SQL network interfaces. …
