CVE-2020-8439

Name of the Vulnerable Software and Affected Versions Monstra CMS versions prior to 3.0.5

Description The issue allows remote authenticated users to take over arbitrary user accounts via a modified login parameter to an edit URI. For example, using login=victim to the "users/21/edit" URI.

Recommendations For Monstra CMS versions prior to 3.0.5, update to version 3.0.5 or later to resolve the issue. As a temporary workaround, consider restricting access to the edit URI for user accounts to minimize the risk of exploitation. Avoid using the login parameter in the affected edit URI until the issue is resolved.
