    Remote Code Execution in scratch-vm

    CVE-2020-14000 · GHSA-vc9j-fhvv-8vrf

    Affected
    • npm scratch-vm <= 0.2.0-prerelease.20200709173451
    Fixed in
    0.2.0-prerelease.20200714185213· Vendor fix available
    Issue
    MIT Lifelong Kindergarten Scratch scratch-vm before 0.2.0-prerelease.20200714185213 loads extension URLs from untrusted project.json files with certain characters, resulting in remote code execution because the URL's content is treated as a script and is executed as a worker. The responsible code is getExtensionIdForOpcode in serialization/sb3.js. The use of is incompatible with a protection mechanism in older versions, in which URLs were split and consequently deserialization attacks were prevented. NOTE: the scratch.mit.edu hosted service is not affected because of the lack of worker scripts.

    Recommended action: Upgrade to 0.2.0-prerelease.20200714185213 (pre-release) or later, then redeploy and verify.A vendor fix does not resolve your finding until you verify it in your own systems.
