Improper Restriction of XML External Entity Reference in Jenkins Chef Sinatra
Packages
| Ecosystem | Package | Affected | Fixed in |
|---|---|---|---|
| Maven | org.jenkins-ci.plugins:sinatra-chef-builder | <= 1.20 | no fix listed |
Details
As written in the advisory (Markdown source, shown as plain text).
Chef Sinatra Plugin 1.20 and earlier does not perform a permission check in a method implementing form validation.
As the plugin does not configure its XML parser to prevent XML external entity (XXE) attacks, attackers can have Jenkins parse a crafted XML response that uses external entities for extraction of secrets from the Jenkins controller or server-side request forgery.
