AI Analysis
Technical Summary
This vulnerability (CVE-2026-13361) is a stack-based buffer overflow (CWE-121) in the IBM Informix Dynamic Server's oninit sq_sgkprepare component. It occurs due to unchecked length fields in the SQL interface, potentially allowing an attacker with network access and limited privileges to execute arbitrary code remotely. The CVSS 3.1 score is 8.8, indicating high impact on confidentiality, integrity, and availability. Affected versions explicitly include =14.10, >=12.10.0 <12.11.0, and =15.0. There is no vendor advisory or patch available at this time, and no known exploits in the wild have been reported.
Potential Impact
Successful exploitation could allow an attacker to execute arbitrary code remotely with limited privileges, leading to full compromise of the affected Informix Dynamic Server instance. The vulnerability impacts confidentiality, integrity, and availability of the system.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is released, restrict network access to the Informix Dynamic Server and monitor for suspicious activity related to the SQL interface.
