CVE-2020-28149Public exploitNetwork attack vector

Remote code execution via CSRF-token script injection

Published Mar 15, 2021 · Updated Aug 4, 2024

Cross-site scripting in myDBR 5.8.3/4262 allows remote attackers to execute arbitrary code by injecting script into a CSRF token. The public record identifies the CSRF token as the injection point but does not disclose the affected endpoint, parameter, or output-encoding failure. Exploitation is network-reachable and unauthenticated but requires a user to interact with the injected content, enabling attacker-controlled script in that user's browser context.
