IBM App Connect Enterprise versions 12.0.1.0 through 12.0.12.27 and 13.0.1.0 through 13.0.8.0 contain a vulnerability due to insecure deserialization of untrusted data. This flaw could allow a local attacker to execute arbitrary code with high impact on confidentiality, integrity, and availability.
AI Analysis
Technical Summary
CVE-2026-17156 is a vulnerability in IBM App Connect Enterprise (versions 12.0.1.0 to 12.0.12.27 and 13.0.1.0 to 13.0.8.0) caused by insecure deserialization of untrusted data (CWE-502). This vulnerability enables a local attacker to execute arbitrary code, potentially compromising the system. The CVSS v3.1 base score is 7.8, indicating high severity, with attack vector local, low attack complexity, no privileges required, user interaction required, and high impact on confidentiality, integrity, and availability.
Potential Impact
Successful exploitation allows a local attacker to execute arbitrary code on the affected system, leading to full compromise of confidentiality, integrity, and availability of the IBM App Connect Enterprise environment. This could result in unauthorized data access, modification, or disruption of service.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. No official fix or patch links are provided in the available data. Until a patch is available, restrict local access to trusted users only and monitor for suspicious activity related to deserialization processes.
