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.

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.

The version of phpMyAdmin installed on the remote host does not correctly handle malicious usernames leading to a SQL injection attack through the designer feature. Note that the scanner has not tested for these issues but has instead relied only on the application's self-reported version number.

The remote Ubuntu 18.04 LTS host has a package installed that is affected by multiple vulnerabilities as referenced in the USN-4639-1 advisory.

  - An issue was discovered in phpMyAdmin before 4.8.5. When the AllowArbitraryServer configuration setting is     set to true, with the use of a rogue MySQL server, an attacker can read any file on the server that the     web server's user can access. This is related to the mysql.allow_local_infile PHP configuration, and the     inadvertent ignoring of options(MYSQLI_OPT_LOCAL_INFILE calls. (CVE-2019-6799)

  - 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  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.

    An attacker must have a valid MySQL account to access the server. (CVE-2020-5504)

  - In phpMyAdmin 4.x before 4.9.5 and 5.x before 5.0.2, a SQL injection vulnerability has been discovered     where certain parameters are not properly escaped when generating certain queries for search actions in     libraries/classes/Controllers/Table/TableSearchController.php. An attacker can generate a crafted database     or table name. The attack can be performed if a user attempts certain search operations on the malicious     database or table. (CVE-2020-10802)

  - In phpMyAdmin 4.x before 4.9.5 and 5.x before 5.0.2, a SQL injection vulnerability was discovered where     malicious code could be used to trigger an XSS attack through retrieving and displaying results (in     tbl_get_field.php and libraries/classes/Display/Results.php). The attacker must be able to insert crafted     data into certain database tables, which when retrieved (for instance, through the Browse tab) can trigger     the XSS attack. (CVE-2020-10803)

  - In phpMyAdmin 4.x before 4.9.5 and 5.x before 5.0.2, a SQL injection vulnerability was found in retrieval     of the current username (in libraries/classes/Server/Privileges.php and     libraries/classes/UserPassword.php). A malicious user with access to the server could create a crafted     username, and then trick the victim into performing specific actions with that user account (such as     editing its privileges). (CVE-2020-10804)

  - 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 attacker could use this flaw to inject malicious SQL in to a query. (CVE-2020-26935)

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

According to its self-reported version, the phpMyAdmin application hosted on the remote web server is 4.0.x prior to 4.8.5. It is, therefore, affected by multiple vulnerabilities.

  - When AllowArbitraryServer configuration set to true,     with the use of a rogue MySQL server, an attacker can     read any file on the server that the web server's user     can access.phpMyadmin attempts to block the use of LOAD     DATA INFILE, but due to a bug in PHP, this check is not     honored. Additionally, when using the 'mysql' extension,     mysql.allow_local_infile is enabled by default. Both of     these conditions allow the attack to occur.
    (CVE-2019-6799)

  - A vulnerability was reported where a specially crafted     username can be used to trigger an SQL injection attack     through the designer feature. (CVE-2019-6798)

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

According to its self-reported version number, the phpMyAdmin application hosted on the remote web server is 4.x prior to 4.8.5. It is, therefore, affected by at least one of the following vulnerabilities:

  - A SQL injection (SQLi) vulnerability exists in phpMyAdmin due to improper validation of user-supplied input.
  An unauthenticated, remote attacker can exploit this to inject or manipulate SQL queries in the back-end database,   resulting in the disclosure or manipulation of arbitrary data (CVE-2019-6798).

  - An arbitrary file read vulnerability exists in phpMyAdmin when the AllowArbitraryServer configuration setting is   set to true. An unauthenticated, remote attacker can exploit this, via a rogue MySQL server, to read arbitrary files   and disclose sensitive information (CVE-2019-6799).

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

This update for phpMyAdmin to version 4.8.5 fixes the following issues :

Security issues fixed :

  - CVE-2019-6799: Fixed an arbitrary file read     vulnerability (boo#1123272)

  - CVE-2019-6798: Fixed a SQL injection in the designer     interface (boo#1123271)

Other changes :

  - Fix rxport to SQL format not available

  - Fix QR code not shown when adding two-factor     authentication to a user account

  - Fix issue with adding a new user in MySQL 8.0.11 and     newer

  - Fix missing table level operations tab

Upstream announcement: # Security fix: phpMyAdmin 4.8.5 is released

The phpMyAdmin team announces the release of **phpMyAdmin version 4.8.5**. Among other bug fixes, this contains **several important security fixes**. Upgrading is highly recommended for all users.

The security fixes involve :

  - Arbitrary file read vulnerability     (https://www.phpmyadmin.net/security/PMASA-2019-1)

  - SQL injection in the Designer interface     (https://www.phpmyadmin.net/security/PMASA-2019-2)

The arbitrary file read vulnerability could also be exploited to delete arbitrary files on the server. This attack requires that phpMyAdmin be run with the `$cfg['AllowArbitraryServer']` directive set to true, which is not the default. An attacker must run a malicious server process that will masquerade as a MySQL server. This exploit has been found and fixed recently in several other related projects and appears to be caused by a bug in PHP (https://bugs.php.net/bug.php?id=77496).

In addition to the security fixes, this release also includes these bug fixes and more as part of our regular release cycle :

  - Export to SQL format not available

  - QR code not shown when adding two-factor authentication     to a user account

  - Issue with adding a new user in MySQL 8.0.11 and newer

  - Frozen interface relating to Text_Plain_Sql plugin

  - Table level Operations tab was missing

And several more. Complete notes are in the ChangeLog file included with this release.
