Senserva AI Opinion for CVE-2006-1547
Apache Struts 1 before 1.2.9 with BeanUtils 1.7 can be forced into denial-of-service through its ActionForm handling, and EPSS puts exploitation at 55%. Struts 1 has been end-of-life for years, so any application still built on it carries this flaw plus everything left unfixed since.
Do this: Inventory Java web applications for Struts 1 dependencies and prioritize migrating or retiring them.
