Phishing via unvalidated login redirect target
Published Feb 20, 2024 · Updated Aug 1, 2024
Open redirect in JumpServer before 3.10.0 allows remote attackers to direct users to external sites through crafted login links. The /core/auth/login/ endpoint accepts a protocol-relative next parameter and returns an HTTP redirect without rejecting the external destination. Exploitation requires a user to open the crafted link, enabling phishing or script delivery under the apparent trust of a JumpServer URL.
