Fixing Logback CVE-2023-6378 in Spring Boot 2.7.x

To remediate CVE‑2023‑6378 in a Spring Boot 2.7.x application, you must replace the default logging starter with a direct Logback 1.2.x dependency (e.g., 1.2.13), because Spring Boot 2.7 cannot use Logback 1.3.x due to the removed StaticLoggerBinder class; the only other option is to upgrade the whole stack to Spring Boot 3.x, Logback 1.4.x, and JDK 11.

Root Cause Analysis of Missing Logs after Tomcat 7→8 Upgrade

After upgrading from Tomcat 7 to Tomcat 8, the application’s mixed log4j‑1.4 and logback‑1.2.3 dependencies caused the SLF4J binder to be loaded nondeterministically, so Tomcat 8 sometimes selected the Log4j binder without a configuration file, resulting in completely missing log output; removing the conflicting jars or enforcing a deterministic class‑loading order restored logging.
