    Nokogiri Command Injection Vulnerability

    CVE-2019-5477 · GHSA-cr5j-953j-xw5p

    Affected
    • RubyGems rexical < 1.0.7
    Fixed in
    1.0.7· Vendor fix available
    Issue
    A command injection vulnerability in Nokogiri v1.10.3 and earlier allows commands to be executed in a subprocess via Ruby's Kernel.open method. Processes are vulnerable only if the undocumented method Nokogiri::CSS::Tokenizer#loadfile is being called with unsafe user input as the filename. This vulnerability appears in code generated by the Rexical gem versions v1.0.6 and earlier. Rexical is used by Nokogiri to generate lexical scanner code for parsing CSS queries. The underlying vulnerability was addressed in Rexical v1.0.7 and Nokogiri upgraded to this version of Rexical in Nokogiri v1.10.4.

    Recommended action: Upgrade to 1.0.7 or later, then redeploy and verify.A vendor fix does not resolve your finding until you verify it in your own systems.
