GSD-2022-24803

Vulnerability from gsd - Updated: 2022-03-31 00:00
Details
### Impact Applications using [Asciidoctor (Ruby)](https://github.com/asciidoctor/asciidoctor) with [asciidoctor-include-ext](https://github.com/jirutka/asciidoctor-include-ext) (prior to version 0.4.0), which render user-supplied input in AsciiDoc markup, may allow an attacker to execute arbitrary system commands on the host operating system. This attack is possible even when `allow-uri-read` is disabled! ### Patches The vulnerability has been fixed in commit c7ea001 (and further improved in cbaccf3), which is included in version [0.4.0](https://rubygems.org/gems/asciidoctor-include-ext/versions/0.4.0). ### Workarounds ```rb require 'asciidoctor/include_ext' class Asciidoctor::IncludeExt::IncludeProcessor # Overrides superclass private method to mitigate Command Injection # vulnerability in asciidoctor-include-ext <0.4.0. def target_uri?(target) target.downcase.start_with?('http://', 'https://') \ && URI.parse(target).is_a?(URI::HTTP) rescue URI::InvalidURIError false end end ``` ### References * https://sakurity.com/blog/2015/02/28/openuri.html
