Does this matter?

Known to be exploited in the wild (CISA KEV, CISA remediation deadline 21 July 2022). Treat as an emergency change: patch or isolate now, then hunt for prior compromise.

Description

ActionForm in Apache Software Foundation (ASF) Struts before 1.2.9 with BeanUtils 1.7 allows remote attackers to cause a denial of service via a multipart/form-data encoded form with a parameter name that references the public getMultipartRequestHandler method, which provides further access to elements in the CommonsMultipartRequestHandler implementation and BeanUtils.
