CVE-2022-0678Network attack vector

Browser script execution via unsanitized redirect URL

Published Feb 19, 2022 · Updated Aug 2, 2024

Cross-site scripting in Microweber before 1.2.11 allows remote attackers to execute script in a victim browser via crafted redirect URLs. The UrlManager::redirect function inserts an untrusted redirect URL into a meta-refresh tag without HTML cleaning, so attacker-controlled markup is reflected into the response. The attack requires a reachable Microweber web endpoint but no authentication; impact is browser-side script execution with confidentiality and integrity effects in the victim session.
