While it marked the end of an era in 2015, the ghost of 7u80 still haunts legacy systems today. This article explores the security vulnerabilities associated with this specific version, why it poses a critical risk to modern infrastructure, and the implications of running "End of Life" (EOL) software. java 7 update 80 vulnerabilities

Ideally, you would uninstall Java 7 entirely and move to Java 8, 11, or 17. But if you have a legacy application that requires Java 7 Update 80 (or any Java 7 version), implement these compensating controls:
Goal: Add a feature to detect and report systems running Java 7 Update 80 (and its known vulnerabilities) so administrators can identify affected hosts and remediate.
