CVE-2019-3686Network attack vector

Browser script execution via unescaped overview parameters

Published Jan 17, 2020 · Updated Sep 17, 2024

Cross-site scripting in SUSE openQA before commit c172e8883d8f32fced5e02f9b6faaacc913df27b allows remote attackers to inject script. The overview summary formatter treated distri and version query parameters as trusted byte streams, causing the template to emit attacker-supplied HTML without escaping. Exploitation requires a user to open a crafted overview request; the injected script runs in the browser under the openQA origin.
