<h1>Security policy<a class="headerlink" href="#security-policy" title="Permalink to this headline">¶</a></h1>
|
||
<p>The phpMyAdmin developer team is putting lot of effort to make phpMyAdmin as
|
||
secure as possible. But still web application like phpMyAdmin can be vulnerable
|
||
to a number of attacks and new ways to exploit are still being explored.</p>
|
||
<p>For every reported vulnerability we issue a phpMyAdmin Security Announcement
|
||
(PMASA) and it get’s assigned a CVE ID as well. We might group similar
|
||
vulnerabilities to one PMASA (eg. multiple XSS vulnerabilities can be announced
|
||
under one PMASA).</p>
|
||
<p>If you think you’ve found a vulnerability, please see <a class="reference internal" href="#reporting-security"><span class="std std-ref">Reporting security issues</span></a>.</p>

<h2>Typical vulnerabilities<a class="headerlink" href="#typical-vulnerabilities" title="Permalink to this headline">¶</a></h2>
|
||
<p>In this section, we will describe typical vulnerabilities, which can appear in
|
||
our code base. This list is by no means complete, it is intended to show
|
||
typical attack surface.</p>

<h3>Cross-site scripting (XSS)<a class="headerlink" href="#cross-site-scripting-xss" title="Permalink to this headline">¶</a></h3>
|
||
<p>When phpMyAdmin shows a piece of user data, e.g. something inside a user’s
|
||
database, all html special chars have to be escaped. When this escaping is
|
||
missing somewhere a malicious user might fill a database with specially crafted
|
||
content to trick an other user of that database into executing something. This
|
||
could for example be a piece of JavaScript code that would do any number of
|
||
nasty things.</p>
|
||
<p>phpMyAdmin tries to escape all userdata before it is rendered into html for the
|
||
browser.</p>

<h3>Cross-site request forgery (CSRF)<a class="headerlink" href="#cross-site-request-forgery-csrf" title="Permalink to this headline">¶</a></h3>
|
||
<p>An attacker would trick a phpMyAdmin user into clicking on a link to provoke
|
||
some action in phpMyAdmin. This link could either be sent via email or some
|
||
random website. If successful this the attacker would be able to perform some
|
||
action with the users privileges.</p>
|
||
<p>To mitigate this phpMyAdmin requires a token to be sent on sensitive requests.
|
||
The idea is that an attacker does not poses the currently valid token to
|
||
include in the presented link.</p>
|
||
<p>The token is regenerated for every login, so it’s generally valid only for
|
||
limited time, what makes it harder for attacker to obtain valid one.</p>

<h3>SQL injection<a class="headerlink" href="#sql-injection" title="Permalink to this headline">¶</a></h3>
|
||
<p>As the whole purpose of phpMyAdmin is to preform sql queries, this is not our
|
||
first concern. SQL injection is sensitive to us though when it concerns the
|
||
mysql control connection. This controlconnection can have additional privileges
|
||
which the logged in user does not poses. E.g. access the <a class="reference internal" href="setup.html#linked-tables"><span class="std std-ref">phpMyAdmin configuration storage</span></a>.</p>
|
||
<p>User data that is included in (administrative) queries should always be run
|
||
through DatabaseInterface::escapeString().</p>

<h3>Brute force attack<a class="headerlink" href="#brute-force-attack" title="Permalink to this headline">¶</a></h3>
|
||
<p>phpMyAdmin on its own does not rate limit authentication attempts in any way.
|
||
This is caused by need to work in stateless environment, where there is no way
|
||
to protect against such kind of things.</p>
|
||
<p>To mitigate this, you can use Captcha or utilize external tools such as
|
||
fail2ban, this is more details described in <a class="reference internal" href="setup.html#securing"><span class="std std-ref">Securing your phpMyAdmin installation</span></a>.</p>
