Name of the Vulnerable Software and Affected Versions
Adminer versions prior to 5.5.0
Description
A server-side request forgery (SSRF) issue exists in the login form's server field validator. The validator only checks leading integers for privileged ports and does not reject non-numeric port values. This allows attackers to inject PDO DSN keys, such as
host= and port=, into the server parameter to bypass restrictions on privileged ports and establish TCP connections to arbitrary internal hosts and ports before authentication.Recommendations
Update to version 5.5.0 or later.
