Summary

OpenStack Skyline before 5.0.1, 6.0.0, and 7.0.0 has a DOM-based Cross-Site Scripting (XSS) vulnerability in the console because document.write is used unsafely. This is relevant when administrators use the console web interface to view instance console logs.

Risk Assessment

An attacker could execute arbitrary JavaScript in the browser of an administrator viewing console logs, potentially leading to session theft or unauthorized actions. This requires administrator interaction with the vulnerable interface.

Recommendation

Update OpenStack Skyline to version 5.0.1, 6.0.0, or 7.0.0 (depending on the branch). Until then, avoid viewing instance console logs through the web interface or restrict access to trusted networks.
