CVE-2022-30120Network attack vector

Reflected XSS via unsanitized stack sort URLs

Published Jun 24, 2022 · Updated Aug 3, 2024

Cross-site scripting in Concrete CMS 8.5.7 and earlier and 9.0.0 through 9.0.2 allows remote attackers to alter page content via crafted URLs. The Dashboard Stacks view_details route emits attacker-controlled sort URLs without sufficient output sanitization. Exploitation requires user interaction in an older browser with built-in XSS protection disabled; modern browsers automatically escape the input.
