CVE-2022-26158Network attack vector

User redirection via trusted client-controlled Host header

Published Feb 28, 2022 · Updated Aug 3, 2024

Open redirect in Cherwell Service Management 10.2.3 allows remote attackers to redirect users to attacker-controlled pages. The web application trusts the client-controlled Host header, reflects its arbitrary domain into the Location response, and returns an HTTP 302 redirect. Exploitation requires a user to follow a crafted request; the redirect can steer that user to an untrusted site, with no reported server-side code execution or service interruption.
