LDAP INJECTION

The 10 most common web and software application vulnerabilities

 * How can your organization defend against LDAP injection attacks?

DEFINITION

Lightweight Directory Access Protocol (LDAP) is a common software protocol
designed to enable anyone on a network to find resources such as other
individuals, files, and devices. Directory services such as LDAP are useful for
intranets. It can also be used to store usernames and passwords as part of a
single sign-on (SSO) system.


SOFTWARE VULNERABILITY SNAPSHOT


The latest report highlights persistent vulnerabilities in web and software
application security, including information disclosure/leakage,
misconfigurations, and insufficient transport layer protection. The report also
emphasizes the risks of vulnerable third-party libraries and the importance of
software supply chain security.

Read the report



WHAT IS LDAP INJECTION?



LDAP injection is a vulnerability in which queries are constructed from
untrusted input without prior validation or sanitization. LDAP uses queries
constructed from predicates that involve the use of special characters (e.g.,
brackets, asterisks, ampersands, or quotes). Metacharacters such as these
control the meaning of the query; thereby, affecting the type and number of
objects retrieved from the underlying directory. If an attacker can submit input
containing these control characters, they can alter the query and change the
intended behavior.

--------------------------------------------------------------------------------




HOW DOES LDAP INJECTION WORK?



The application architecture that supports LDAP includes both server-side and
client-side components. The LDAP queries submitted to the server are known as
LDAP search filters, which are constructed using prefix notation. Below is an
example of an LDAP search filter:

find("(&(cn=" + username +")(userPassword=" + pass +"))")

This prefix filter notation instructs the query to find an LDAP node with the
given username and password. Consider a scenario where this query is constructed
by appending the username and password strings obtained from an HTML form. If
these user-controlled values are appended to the LDAP search filter without any
validation or sanitization, a username and password value of ‘*’ changes the
intended meaning of the query and returns a list of all users.

Special characters other than ‘*’ can also create malicious queries. If the
username value is set to ‘*)(cn=*))(|(cn=*’, the effective search filter
becomes:

find("(&(cn=*)(cn=*))(|(cn=*)(userPassword=" + pass +"))")

The highlighted condition in the above query always evaluates to true. If this
query is used within an authentication flow, an attacker can easily bypass
authentication controls with the above payload.

There are a multitude of LDAP injection exploits that can be executed against a
vulnerable server. Additionally, LDAP servers often store information such as
users, roles, permissions, and related objects provisioned to them which, if
compromised, can be devastating.

--------------------------------------------------------------------------------




HOW CAN YOUR ORGANIZATION DEFEND AGAINST LDAP INJECTION ATTACKS?



LDAP injection attacks primarily occur due to missing or weak input validation.
Validation consists of rejecting malformed input or stripping malicious LDAP
control characters before including untrusted input within a query.

Below are several actionable methods you can leverage to protect your
organization:

Enforce input validation. Prior to including untrusted input in LDAP queries,
the input should be validated against a prefer list of allowed strings or
characters. This validation should always be conducted server-side even if the
input is previously validated client-side.

Structured inputs like social security numbers, phone numbers, and email
addresses can be validated using a strong regular expression pattern. Inputs
like usernames should be validated against an approved set of characters that
exclude LDAP filter control characters.

Escape input with encoding. Escape user-controlled input strings in such a way
that any control characters in the input don’t change the intended meaning of
the LDAP search filter. For example, in a Java application, metacharacters in an
LDAP query can be prepared with backslashes as escape characters. With this
method, untrusted inputs are appended to a search filter are as literal string
values, not as LDAP predicates.

Harden directory authorization. This defense technique is meant to minimize the
impact of any injection attempt by employing the principle of least privilege.
The LDAP account used for binding the directory in an application must have
restricted access. With this approach, only authorized LDAP queries can be
executed against the LDAP server.
