wcf soap security

The wcf soap security tag covers discussions about vulnerabilities and fixes in Windows Communication Foundation (WCF) services that use SOAP protocols. A recent thread highlights a CISA advisory (ICSA-26-155-01) about hard-coded credentials in NAVTOR NavBox 4.16.1.20, a WCF SOAP implementation used in maritime operational technology. The vulnerability allows local authenticated attackers to access privileged methods if SOAP is enabled, though it is not remotely exploitable. The fix is included in version 4.17.2.6. This tag is relevant for IT and OT security professionals managing WCF-based systems, particularly those concerned with credential management, SOAP endpoint hardening, and patching industrial control systems.
