CSRF vulnerability in login form

PMASA-2019-4

Announcement-ID: PMASA-2019-4

Date: 2019-06-04

Summary

CSRF vulnerability in login form

Description

A vulnerability was found that allows an attacker to trigger a CSRF attack against a phpMyAdmin user. The attacker can trick the user, for instance through a broken <img> tag pointing at the victim’s phpMyAdmin database, and the attacker can potentially deliver a payload (such as a specific INSERT or DELETE statement) through the victim.

Severity

We consider this vulnerability to be severe.

Mitigation factor

Only the ‘cookie’ auth_type is affected; users can temporary use phpMyAdmin’s http authentication as a workaround.

Affected Versions

All versions prior to phpMyAdmin 4.9.0 are affected, probably at least as old as version 4.0 (perhaps even earlier)

Solution

Upgrade to phpMyAdmin 4.9.0 or newer or apply patch listed below.
