How to Fix CVE-2020-26249

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

red-dashboard fixed: 0.1.7a 
pip install red-dashboard>=0.1.7a
Verify Direct and Transitive Dependencies

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

pip show red-dashboard

How to Check if You Are Affected

To determine whether your Python environment is affected by CVE-2020-26249, inspect your installed packages using pip:

pip show red-dashboard

Analyze the terminal output to locate any version of Red dashboard in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 0.1.7a), your application is affected.

Note: The pip show red-dashboard command checks currently installed packages in your active Python environment.

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 Red dashboard, 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

### Impact A RCE exploit has been discovered in the Red Discord Bot - Dashboard Webserver: this exploit allows Discord users with specially crafted Server names and Usernames/Nicknames to inject code into the webserver front-end code. By abusing this exploit, it's possible to perform destructive actions and/or access sensitive information. ### Patches This high severity exploit has been fixed on version `0.1.7a`. ### Workarounds There are no workarounds, bot owners must upgrade their relevant packages (Dashboard module and Dashboard webserver) in order to patch this issue ### References - 99d88b8 - a6b9785 ### For more information If you have any questions or comments about this advisory: * Open an issue in [Cog-Creators/Red-Dashboard](https://github.com/Cog-Creators/Red-Dashboard/issues/new/choose) * Over on the official [Red Server](https://discord.gg/red) or at the Third Party Server [Toxic Layer](https://discord.gg/vQZTdB9)
