Do I really need CURL on all my Windows devices?

us flag

So a vulnerability scanner has revealed that I have a version of CURL that is out of date on basically all of my machines. Environments in question are Windows 10 and Server 2019. From what I can tell it was Windows 10 1804 that first issued it.

To my understanding CURL is a command-line tool for sending data using network protocols. But do I really need it? In what instance would I need to have CURL handy to do things in Windows? I know there's some CLI commands but nobody invokes them here - is there some background thing users don't interact with that needs it in modern versions of Windows? We have two IIS servers (one hosting an internal site and one doing some WSUS stuff) but beyond that I have no leads.

This is the first time such a thing has been reported, so I have never had to question whether or not I need it to begin with. I could patch it, but at the same time I wonder if I'm better off just getting rid of it. Unfortunately I don't know if it's truly needed by Windows or something.

We can't tell you if your organization needs curl. Curl has been a default component of the Windows operating system for six years.

If there is a vulnerability in curl, it would need to be addressed by the vendor (Microsoft), and as part of the usual and customary monthly cumulative update. Given that this is rated by the vulnerability scanner as only a medium, the chances of this being addressed in a monthly update are low. If it is addressed, it may be in an annual release.

This type of noise is common, if you haven't seen it before you should get accustomed to it if your scanner isn't sophisticated enough to measure the workarounds or compensating controls you will implement.

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
