Technical details

IBM App Connect Enterprise is vulnerable to sensitive information disclosure (CWE-532) within its Discovery Connector nodes. The application incorrectly records potentially sensitive data into log files, which may be accessible to local users or through log management interfaces. While the CVSS vector provided by the vendor indicates a network attack vector (AV:N), the description specifically highlights risks from local users reading log files. An attacker who gains access to these logs can extract confidential information, which could facilitate further attacks. The issue is resolved in IBM App Connect Enterprise versions 13.0.8.0 and 12.0.12.28.

Affected products

IBM App Connect Enterprise 13.0.1.0 - 13.0.7.2
