Some URIs in IBM API Connect 2018.1 and 2018.4.1.3 disclose system specification information like the machine id, system uuid, filesystem paths, network interface names along with their mac addresses. An attacker can use this information in targeted attacks. IBM X-Force ID: 156542.

Security readout for executives and security teams

IBM API Connect 2018.1 and 2018.4.1.3 expose system details through some URIs. The leaked data can include machine identifiers, UUIDs, filesystem paths, network interface names, and MAC addresses. This is not a direct takeover bug, but it can help attackers plan targeted attacks. Exposure appears limited to IBM API Connect 2018.1 and 2018.4.1.3. Risk is higher where affected management or API Connect interfaces are reachable from untrusted networks. Prioritize remediation for internet-facing or partner-accessible API Connect deployments. Internal-only systems still merit scheduled remediation because leaked host details can support later intrusion planning. Mitigation focus: Check IBM advisory for official fixed levels or mitigation instructions.; Upgrade affected IBM API Connect deployments according to vendor guidance.; Restrict access to API Connect interfaces from untrusted networks..
