CVE-2020-5337Network attack vector

Unauthenticated phishing via arbitrary URL redirection

Published May 4, 2020 · Updated Sep 17, 2024

Open redirect in Archer Platform before 6.7 P1 allows remote attackers to send users to arbitrary web URLs through crafted links. Archer has not published the affected endpoint or the validation error that permits an attacker-controlled redirect destination. No authentication is required, but an application user must follow the crafted link; the resulting redirect supports phishing to malicious sites.
