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 assigne 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> <div class="section" id="typical-vulnerabilities"> <h2>Typical vulnerabilities<a class="headerlink" href="#typical-vulnerabilities" title="Permalink to this headline">¶</a></h2> <p>In this secion, 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> <div class="section" id="cross-site-scripting-xss"> <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> <div class="admonition seealso"> <p class="first admonition-title">See also</p> <p class="last"><a class="reference external" href="https://en.wikipedia.org/wiki/Cross-site_scripting">Cross-site scripting on Wikipedia</a></p> </div> </div> <div class="section" id="cross-site-request-forgery-csrf"> <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> <div class="admonition seealso"> <p class="first admonition-title">See also</p> <p class="last"><a class="reference external" href="https://en.wikipedia.org/wiki/Cross-site_request_forgery">Cross-site request forgery on Wikipedia</a></p> </div> </div> <div class="section" id="sql-injection"> <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.

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::escapeSring().</p> <div class="admonition seealso"> <p class="first admonition-title">See also</p> <p class="last"><a class="reference external" href="https://en.wikipedia.org/wiki/SQL_injection">SQL injection on Wikipedia</a></p> </div> </div> <div class="section" id="brute-force-attack"> <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.
