CVE-2020-11009
Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.
NVD · uneditedIn Rundeck before version 3.2.6, authenticated users can craft a request that reveals Execution data and logs and Job details that they are not authorized to see. Depending on the configuration and the way that Rundeck is used, this could result in anything between a high severity risk, or a very low risk. If access is tightly restricted and all users on the system have access to all projects, this is not really much of an issue. If access is wider and allows login for users that do not have access to any projects, or project access is restricted, there is a larger issue. If access is meant to be restricted and secrets, sensitive data, or intellectual property are exposed in Rundeck execution output and job data, the risk becomes much higher. This vulnerability is patched in version 3.2.6
Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.
dbcve analysis · high confidenceRundeck before 3.2.6 contains an authorization bypass vulnerability where authenticated users can craft specific requests to access Execution data, logs, and Job details that they are not authorized to view. This is essentially an Insecure Direct Object Reference (IDOR) flaw allowing unauthorized access to sensitive execution output and job information.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.
dbcve checksWork through these to decide whether this CVE applies to you.
-
Check Rundeck version from the web interfaceLog into the Rundeck UI and navigate to the 'System' menu (gear icon) > 'About' or check the footer of any page for the version numberAffected if The displayed version is lower than 3.2.6 (for example, 3.2.5, 3.2.4, etc.)
-
Check Rundeck version via APIMake an authenticated GET request to the Rundeck API endpoint: /api/14/system/info or /api/41/system/info (depending on your version). Example: curl -k -H "Accept: application/json" https://your-rundeck-server/api/14/system/infoAffected if The API response shows a version field lower than 3.2.6
-
Check Rundeck version from startup logsInspect the Rundeck server logs produced at startup, typically found in /var/log/rundeck/service.log or /opt/rundeck/var/logs/service.log, or the rundeck bootstrap logAffected if The startup log contains a version identifier lower than 3.2.6
-
Check package or installation manager versionIf installed via a package manager (yum, apt, RPM), run: rpm -q rundeck or dpkg -l rundeck. If using Docker, check the image tag: docker images | grep rundeckAffected if The installed package or container image version is tagged or reported as lower than 3.2.6
If the installed Rundeck version is below 3.2.6, the environment is affected by this IDOR authorization bypass vulnerability.
