A CSRF issue in phpMyAdmin 4.9.0.1 allows deletion of any server in the Setup page.

The remote Ubuntu 16.04 ESM / 18.04 ESM / 20.04 ESM host has a package installed that is affected by multiple vulnerabilities as referenced in the USN-4843-1 advisory.

  - libraries/common.inc.php in phpMyAdmin 4.0.x before 4.0.10.7, 4.1.x before 4.1.14.8, and 4.2.x before     4.2.13.1 allows remote attackers to cause a denial of service (resource consumption) via a long password.
    (CVE-2014-9218)

  - An issue was discovered in phpMyAdmin. A specially crafted database name could be used to run arbitrary     PHP commands through the array export feature. All 4.6.x versions (prior to 4.6.4), 4.4.x versions (prior     to 4.4.15.8), and 4.0.x versions (prior to 4.0.10.17) are affected. (CVE-2016-6609)

  - An issue was discovered in phpMyAdmin. In the user interface preference feature, a user can execute an SQL     injection attack against the account of the control user. All 4.6.x versions (prior to 4.6.4), 4.4.x     versions (prior to 4.4.15.8), and 4.0.x versions (prior to 4.0.10.17) are affected. (CVE-2016-6619)

  - An issue was discovered in phpMyAdmin. An authenticated user can trigger a denial-of-service (DoS) attack     by entering a very long password at the change password dialog. All 4.6.x versions (prior to 4.6.4), 4.4.x     versions (prior to 4.4.15.8), and 4.0.x versions (prior to 4.0.10.17) are affected. (CVE-2016-6630)

  - An issue was discovered in phpMyAdmin. It is possible to bypass AllowRoot restriction     ($cfg['Servers'][$i]['AllowRoot']) and deny rules for username by using Null Byte in the username. All     4.6.x versions (prior to 4.6.5), 4.4.x versions (prior to 4.4.15.9), and 4.0.x versions (prior to     4.0.10.18) are affected. (CVE-2016-9849)

  - An issue was discovered in phpMyAdmin. When the arg_separator is different from its default & value, the     CSRF token was not properly stripped from the return URL of the preference import action. All 4.6.x     versions (prior to 4.6.5), 4.4.x versions (prior to 4.4.15.9), and 4.0.x versions (prior to 4.0.10.18) are     affected. (CVE-2016-9866)

  - An issue was discovered in libraries/common.inc.php in phpMyAdmin 4.0 before 4.0.10.20, 4.4.x, 4.6.x, and     4.7.0 prereleases. The restrictions caused by $cfg['Servers'][$i]['AllowNoPassword'] = false are bypassed     under certain PHP versions (e.g., version 5). This can allow the login of users who have no password set     even if the administrator has set $cfg['Servers'][$i]['AllowNoPassword'] to false (which is also the     default). This occurs because some implementations of the PHP substr function return false when given ''     as the first argument. (CVE-2017-18264)

  - phpMyAdmin 4.0, 4.4, and 4.6 are vulnerable to a DOS weakness in the table editing functionality     (CVE-2017-1000014)

  - phpMyAdmin 4.0, 4.4, and 4.6 are vulnerable to a CSS injection attack through crafted cookie parameters     (CVE-2017-1000015)

  - Cross-site scripting (XSS) vulnerability in db_central_columns.php in phpMyAdmin before 4.7.8 allows     remote authenticated users to inject arbitrary web script or HTML via a crafted URL. (CVE-2018-7260)

  - An issue was discovered in js/designer/move.js in phpMyAdmin before 4.8.2. A Cross-Site Scripting     vulnerability has been found where an attacker can use a crafted database name to trigger an XSS attack     when that database is referenced from the Designer feature. (CVE-2018-12581)

  - An attacker can exploit phpMyAdmin before 4.8.4 to leak the contents of a local file because of an error     in the transformation feature. The attacker must have access to the phpMyAdmin Configuration Storage     tables, although these can easily be created in any database to which the attacker has access. An attacker     must have valid credentials to log in to phpMyAdmin; this vulnerability does not allow an attacker to     circumvent the login system. (CVE-2018-19968)

  - In phpMyAdmin before 4.8.4, an XSS vulnerability was found in the navigation tree, where an attacker can     deliver a payload to a user through a crafted database/table name. (CVE-2018-19970)

  - An issue was discovered in phpMyAdmin before 4.8.5. A vulnerability was reported where a specially crafted     username can be used to trigger a SQL injection attack through the designer feature. (CVE-2019-6798)

  - An issue was discovered in phpMyAdmin before 4.9.0.1. A vulnerability was reported where a specially     crafted database name can be used to trigger an SQL injection attack through the designer feature.
    (CVE-2019-11768)

  - An issue was discovered in phpMyAdmin before 4.9.0. 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) to the victim. (CVE-2019-12616)

  - A CSRF issue in phpMyAdmin 4.9.0.1 allows deletion of any server in the Setup page. (CVE-2019-12922)

  - phpMyAdmin before 4.9.2 does not escape certain Git information, related to     libraries/classes/Display/GitRevision.php and libraries/classes/Footer.php. (CVE-2019-19617)

  - In phpMyAdmin 4 before 4.9.4 and 5 before 5.0.1, SQL injection exists in the user accounts page. A     malicious user could inject custom SQL in place of their own username when creating queries to this page.
    An attacker must have a valid MySQL account to access the server. (CVE-2020-5504)

  - phpMyAdmin before 4.9.6 and 5.x before 5.0.3 allows XSS through the transformation feature via a crafted     link. (CVE-2020-26934)

  - An issue was discovered in SearchController in phpMyAdmin before 4.9.6 and 5.x before 5.0.3. A SQL     injection vulnerability was discovered in how phpMyAdmin processes SQL statements in the search feature.
    An attacker could use this flaw to inject malicious SQL in to a query. (CVE-2020-26935)

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

This update for phpMyAdmin to version 4.9.4 fixes the following issues :

  - CVE-2020-5504: SQL injection in user accounts page     (boo#1160456).

A cross-site request forgery (XSRF) vulnerability exists in the Setup page of phpMyAdmin. A remote attacker can exploit this by tricking a user into visiting a specially crafted web page, allowing the attacker to delete any server in the setup page by creating a fake hyperlink containing the malicious request it wants the victim's web browser to execute. 

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.

Upstream announcement :

Welcome to **phpMyAdmin 4.9.1**, a bugfix release.

This is a regularly-schedule bugfix release that also includes some security hardening measures.

We wish to point out that this also includes a routine fix for an issue that has been reported as CVE-2019-12922. The fix for this has been in our release queue to be part of this release, however it is the opinion of the team that the reported attack vector did not justify a separate release.

This release includes fixes for many bugs, including :

  - Editing columns with CURRENT_TIMESTAMP for MySQL     versions 8.0.13 and newer

  - Compatibility issues with PHP 8

  - Export of GIS visualization

  - Enhanced descriptions for several collation types

  - Creating a user with a single quote in the password     string

  - Unexpected quotes during import and export on text     fields

  - Improvements to adding new tables to Designer

  - Fix an issue where an authenticated user could trigger     heavy traffic between the database server and web server

  - Fix a weakness where an attacker, under certain     conditions, working at the same time as an administrator     is using the setup script, could delete a server from     the setup script

There are many, many more bug fixes thanks to the efforts of our developers, Google Summer of Code applicants, and other contributors.
