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

GHSA-V222-6MR4-QJ29

Vulnerability from github – Published: 2022-03-31 23:27 – Updated: 2023-05-16 15:46

Summary

Command Injection vulnerability in asciidoctor-include-ext

Details

Impact

Applications using Asciidoctor (Ruby) with 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!~~ (EDIT: it’s not)

Patches

The vulnerability has been fixed in commit c7ea001 (and further improved in cbaccf3), which is included in version 0.4.0.

Workarounds

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

The MITRE ATT&CK techniques below are AI-generated suggestions, inferred from the description of the vulnerability by the CIRCL/vulnerability-attack-technique-classification-roberta-base model, served locally by ML-Gateway. They have not been verified by an analyst and are provided for guidance only.
The approach is described in our paper Mapping CVEs to MITRE ATT&CK Techniques: A Curated Gold-Set Classifier and the Limits of LLM-Assisted Label Expansion.
