How to Fix CVE-2019-11291

To remediate this vulnerability, upgrade all affected Rabbit common dependencies to a patched release. Both direct and transitive dependencies should be checked, as frameworks or security libraries may pull in vulnerable versions transitively.

rabbit_common fixed: 3.7.20 
Upgrade rabbit_common to 3.7.20
rabbit_common fixed: 3.8.1 
Upgrade rabbit_common to 3.8.1
Verify Direct and Transitive Dependencies

Run the following command in your project directory to verify that all resolved dependencies use the patched release: 

inspect dependencies for rabbit_common

How to Check if You Are Affected

To determine whether your application is affected by CVE-2019-11291, inspect your project dependencies for Rabbit common:

inspect dependencies for rabbit_common

Analyze the terminal output to locate any version of Rabbit common in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 3.7.20), your application is affected.

Note: Verify declared build manifests and deployed runtime container environments.

Technical Details

Vulnerability Mechanism & Technical Analysis

This vulnerability is classified under CWE-79: Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting'), where the product does not neutralize or incorrectly neutralizes user-controllable input before it is placed in output that is used as a web page that is served to other users. In Rabbit common, software state validation or input boundaries are circumvented during processing. Review the official source advisory statement below for specific affected components, classes, and reproduction details.

Source Advisory Statement

Pivotal RabbitMQ, 3.7 versions prior to v3.7.20 and 3.8 version prior to v3.8.1, and RabbitMQ for PCF, 1.16.x versions prior to 1.16.7 and 1.17.x versions prior to 1.17.4, contain two endpoints, federation and shovel, which do not properly sanitize user input. A remote authenticated malicious user with administrative access could craft a cross site scripting attack via the vhost or node name fields that could grant access to virtual hosts and policy management information.
