|
|
|
|
|
<p>A command injection vulnerability in Nokogiri allows commands to be
|
|
|
|
|
|
executed in a subprocess by Ruby’s Kernel.open method. Processes are
|
|
|
|
|
|
vulnerable only if the undocumented method
|
|
|
|
|
|
Nokogiri::CSS::Tokenizer#load_file is being passed untrusted user input.
|
|
|
|
|
|
</p>

<impact type="normal">
|
|
|
|
|
|
<p>A remote attacker could possibly execute arbitrary code with the
|
|
|
|
|
|
privileges of the process.

|

<workaround>
|
|
|
|
|
|
<p>Avoid calling the undocumented method Nokogiri::CSS::Tokenizer#load_file
|
|
|
|
|
|
with untrusted user input.
