Technical Analysis
Unlike CVE-2017-5638, which was exploitable out of the box, since it targeted Struts’ Jakarta multipart parser, this vulnerability requires a certain set of circumstances to be true in order for Struts to be exploitable. Since Struts is a web application framework, this will depend entirely on the application the developers have created.
I don’t know how common this particular scenario is. Please read the security bulletin for more information. However, what I do know is that this CVE falls somewhere after CVE-2017-5638 and CVE-2018-11776 on the exploitability scale, from most exploitable to least: a parser flaw, a configuration flaw, and a programming flaw.
So, definitely patch this, but also follow Struts development best practices, including those outlined in their security bulletins. No measure of mitigations will protect you from poorly written code.
