How to Fix CVE-2017-16833

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

gemirro fixed: 0.16.0 
Upgrade gemirro to 0.16.0
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 gemirro

How to Check if You Are Affected

To determine whether your application is affected by CVE-2017-16833, inspect your project dependencies for Gemirro:

inspect dependencies for gemirro

Analyze the terminal output to locate any version of Gemirro in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 0.16.0), 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 Gemirro, 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

Stored cross-site scripting (XSS) vulnerability in Gemirro before 0.16.0 allows attackers to inject arbitrary web script via a crafted javascript: URL in the "homepage" value of a ".gemspec" file. A ".gemspec" file must be created with a JavaScript URL in the homepage value. This can be used to build a gem for upload to the Gemirro server, in order to achieve stored XSS via the author name hyperlink.
