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.

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 sanitize the database name parameter inside the Designer feature, leading to a Cross-Site Scripting (XSS) vulnerability. Note that the scanner has not tested for these issues but has instead relied only on the application's self-reported version number.

This update for phpMyAdmin fixes multiple issues.

Security issues fixed :

  - CVE-2018-12613: File inclusion and remote code execution     attack (boo#1098751)

  - CVE-2018-12581: XSS in Designer feature (boo#1098752)

This update to version 4.8.2 also contains number of upstream bug fixes and improvements.

Upstream announcement :

The phpMyAdmin team is pleased to announce the release of **phpMyAdmin version 4.8.2**. Among other bug fixes, this contains an important security update and it is highly recommended that all users upgrade immediately.

The urgent vulnerability allows an authenticated attacker to exploit a phpMyAdmin feature to show and potentially execute files on the server. PHP open_basedir restrictions mitigate the effect of this flaw. For further details, see the PMASA announcement .

A second flaw was also fixed allowing an attacker to use a specially crafted database name to trick a user in to executing a cross-site scripting (XSS) attack in the Designer feature .

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

  - WHERE 0 clause causes a fatal error

  - Fix missing 'INDEX' icon

Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

The phpMyAdmin development team reports : Summary XSS in Designer feature Description A Cross-Site Scripting vulnerability was found in the Designer feature, where an attacker can deliver a payload to a user through a specially crafted database name. Severity We consider this attack to be of moderate severity. Summary File inclusion and remote code execution attack Description A flaw has been discovered where an attacker can include (view and potentially execute) files on the server.

The vulnerability comes from a portion of code where pages are redirected and loaded within phpMyAdmin, and an improper test for whitelisted pages.

An attacker must be authenticated, except in these situations :

- $cfg['AllowArbitraryServer'] = true: attacker can specify any host he/she is already in control of, and execute arbitrary code on phpMyAdmin

- $cfg['ServerDefault'] = 0: this bypasses the login and runs the vulnerable code without any authentication Severity We consider this to be severe. Mitigation factor Configuring PHP with a restrictive `open_basedir` can greatly restrict an attacker's ability to view files on the server. Vulnerable systems should not be run with the phpMyAdmin directives $cfg['AllowArbitraryServer'] = true or $cfg['ServerDefault'] = 0
