4 The phpMyAdmin developer team is putting lot of effort to make phpMyAdmin as
5 secure as possible. But still web application like phpMyAdmin can be vulnerable
6 to a number of attacks and new ways to exploit are still being explored.
8 For every reported vulnerability we issue a phpMyAdmin Security Announcement
9 (PMASA) and it get's assigned a CVE ID as well. We might group similar
10 vulnerabilities to one PMASA (eg. multiple XSS vulnerabilities can be announced
13 If you think you've found a vulnerability, please see :ref:`reporting-security`.
15 Typical vulnerabilities
16 -----------------------
18 In this section, we will describe typical vulnerabilities, which can appear in
19 our code base. This list is by no means complete, it is intended to show
20 typical attack surface.
22 Cross-site scripting (XSS)
23 ++++++++++++++++++++++++++
25 When phpMyAdmin shows a piece of user data, e.g. something inside a user's
26 database, all html special chars have to be escaped. When this escaping is
27 missing somewhere a malicious user might fill a database with specially crafted
28 content to trick an other user of that database into executing something. This
29 could for example be a piece of JavaScript code that would do any number of
32 phpMyAdmin tries to escape all userdata before it is rendered into html for the

39 Cross-site request forgery (CSRF)
40 +++++++++++++++++++++++++++++++++
42 An attacker would trick a phpMyAdmin user into clicking on a link to provoke
43 some action in phpMyAdmin. This link could either be sent via email or some
44 random website. If successful this the attacker would be able to perform some
45 action with the users privileges.
47 To mitigate this phpMyAdmin requires a token to be sent on sensitive requests.
48 The idea is that an attacker does not poses the currently valid token to
49 include in the presented link.
51 The token is regenerated for every login, so it's generally valid only for
52 limited time, what makes it harder for attacker to obtain valid one.
56 `Cross-site request forgery on Wikipedia <https://en.wikipedia.org/wiki/Cross-site_request_forgery>`_
61 As the whole purpose of phpMyAdmin is to preform sql queries, this is not our
62 first concern. SQL injection is sensitive to us though when it concerns the
63 mysql control connection. This controlconnection can have additional privileges
64 which the logged in user does not poses. E.g. access the :ref:`linked-tables`.
66 User data that is included in (administrative) queries should always be run
67 through DatabaseInterface::escapeString().

76 phpMyAdmin on its own does not rate limit authentication attempts in any way.
77 This is caused by need to work in stateless environment, where there is no way
78 to protect against such kind of things.
80 To mitigate this, you can use Captcha or utilize external tools such as
81 fail2ban, this is more details described in :ref:`securing`.
