    I really like these secondary scoring factors, not just scoring the vuln itself, but how it's being attacked.

    Wow! At first sight I was sure it was a joke, but no. What a time...

      Presumably this is like many other graphics tool vulnerabilities this works by the attacker persuading a user to open a file that exercises the bug. Not terribly unusual.

        I don't think so:

        > User Interaction: None

        > Out-of-bounds read in Windows Paint allows an unauthorized attacker to execute code over a network.

          > An unauthenticated attacker could exploit this vulnerability by sending a specially crafted packet to an affected service over the network.

          What server is MS Paint running or what services does it provide?

          Edit: Apparently you can use it to print an image from the command-line. Is that how this is being exploited?

      Of course the valuable link is down-weighted/buried in the HN discussion...

      When they find a CVE RCE in minesweeper then you know it’s all over

    Code execution, sure, paint has been used to write executable code too, so why not.

    But remote? How

      "An unauthenticated attacker could exploit this vulnerability by sending a specially crafted packet to an affected service over the network. Successful exploitation could allow the attacker to execute code on the target system. No authentication or user interaction is required.."

      Still, the question remains... How?

      • IanCal33 minutes ago
        It mentions that it may rely on other services or security measures running- I wonder if there’s something like this hitting a firewall or av and then that calling out to paint to check file type or size out something like that?

        The direct implication is that current generations of ms paint are a “service over the network.” Probably a theoretically possible RPC end point of svchost.exe
    • VorpalWay40 minutes ago
      I'm thankfully out of the loop on Windows these days, but as I remember it Paint did not have any network features? Is that still true? If if is, maybe it is a misfiling of the CVE and it isn't remote?

      Or are they chaining a browser auto opening a download in paint, (but browsers shouldn't do that)...

      • kuboble31 minutes ago
        These days paint has copilot...

          Why for the love of everything that is good does MS Paint have network trash in it. It's a super simple bitmap editor. Like Notepad, it's simple and just works.

          Make a new product and bundle that as an option if you want to drastically change the functionality.

        • robotnikman26 minutes ago
          This is the only network feature paint has iirc, so that's probably it.
    • TZubiri21 minutes ago
      Maybe because a .bmp file could be sent remotely.

      Or maybe after the .bmp file is executed, it can install something that opens an outbound TCP connection to its C2, and thus can receive commands. Would not need admin privileges because it doesn't open a port, just 'outbound' connections, like a long-poll.

    • Sohcahtoa829 minutes ago
      Because the definition of "remote" has been expanded in the name of resume-driven development to include sending a malicious file that a victim has to open.
