Common Weakness Enumeration (CWE)

Common Attack Pattern Enumeration and Classification (CAPEC)

  • Accessing, Modifying or Executing Executable Files
    An attack of this type exploits a system's configuration that allows an attacker to either directly access an executable file, for example through shell access; or in a possible worst case allows an attacker to upload a file and then execute it. Web servers, ftp servers, and message oriented middleware systems which have many integration points are particularly vulnerable, because both the programmers and the administrators must be in synch regarding the interfaces and the correct privileges for each interface.
  • Leverage Executable Code in Non-Executable Files
    An attack of this type exploits a system's trust in configuration and resource files, when the executable loads the resource (such as an image file or configuration file) the attacker has modified the file to either execute malicious code directly or manipulate the target process (e.g. application server) to execute based on the malicious configuration parameters. Since systems are increasingly interrelated mashing up resources from local and remote sources the possibility of this attack occurring is high. The attack can be directed at a client system, such as causing buffer overrun through loading seemingly benign image files, as in Microsoft Security Bulletin MS04-028 where specially crafted JPEG files could cause a buffer overrun once loaded into the browser. Another example targets clients reading pdf files. In this case the attacker simply appends javascript to the end of a legitimate url for a pdf (http://www.gnucitizen.org/blog/danger-danger-danger/) http://path/to/pdf/file.pdf#whatever_name_you_want=javascript:your_code_here The client assumes that they are reading a pdf, but the attacker has modified the resource and loaded executable javascript into the client's browser process. The attack can also target server processes. The attacker edits the resource or configuration file, for example a web.xml file used to configure security permissions for a J2EE app server, adding role name "public" grants all users with the public role the ability to use the administration functionality. The server trusts its configuration file to be correct, but when they are manipulated, the attacker gains full control.
  • Blue Boxing
    This type of attack against older telephone switches and trunks has been around for decades. A tone is sent by an adversary to impersonate a supervisor signal which has the effect of rerouting or usurping command of the line. While the US infrastructure proper may not contain widespread vulnerabilities to this type of attack, many companies are connected globally through call centers and business process outsourcing. These international systems may be operated in countries which have not upgraded Telco infrastructure and so are vulnerable to Blue boxing. Blue boxing is a result of failure on the part of the system to enforce strong authorization for administrative functions. While the infrastructure is different than standard current applications like web applications, there are historical lessons to be learned to upgrade the access control for administrative functions.
  • Restful Privilege Elevation
    Rest uses standard HTTP (Get, Put, Delete) style permissions methods, but these are not necessarily correlated generally with back end programs. Strict interpretation of HTTP get methods means that these HTTP Get services should not be used to delete information on the server, but there is no access control mechanism to back up this logic. This means that unless the services are properly ACL'd and the application's service implementation are following these guidelines then an HTTP request can easily execute a delete or update on the server side. The attacker identifies a HTTP Get URL such as http://victimsite/updateOrder, which calls out to a program to update orders on a database or other resource. The URL is not idempotent so the request can be submitted multiple times by the attacker, additionally, the attacker may be able to exploit the URL published as a Get method that actually performs updates (instead of merely retrieving data). This may result in malicious or inadvertent altering of data on the server.
  • Target Programs with Elevated Privileges
    This attack targets programs running with elevated privileges. The attacker would try to leverage a bug in the running program and get arbitrary code to execute with elevated privileges. For instance an attacker would look for programs that write to the system directories or registry keys (such as HKLM, which stores a number of critical Windows environment variables). These programs are typically running with elevated privileges and have usually not been designed with security in mind. Such programs are excellent exploit targets because they yield lots of power when they break. The malicious user try to execute its code at the same level as a privileged system call.

installed and configured. (CVE-2008-4796, MSA-09-0003)

It was discovered that Smarty (also included in Moodle), did not
correctly filter certain inputs. An authenticated remote attacker
could exploit this to execute arbitrary PHP commands as the web server
user. (CVE-2008-4810, CVE-2008-4811, CVE-2009-1669)

It was discovered that the unused SpellChecker extension in Moodle did
not correctly handle temporary files. If the tool had been locally
modified, it could be made to overwrite arbitrary local files via
symlinks. (CVE-2008-5153)

Mike Churchward discovered that Moodle did not correctly filter Wiki
page titles in certain areas. An authenticated remote attacker could
exploit this to cause cross-site scripting (XSS), which could be used
to modify or steal confidential data of other users within the same
web domain. (CVE-2008-5432, MSA-08-0022)

It was discovered that the HTML sanitizer, 'Login as' feature, and
logging in Moodle did not correctly handle certain inputs. An
authenticated remote attacker could exploit this to generate XSS,
which could be used to modify or steal confidential data of other
users within the same web domain. (CVE-2008-5619, CVE-2009-0500,
CVE-2009-0502, MSA-08-0026, MSA-09-0004, MSA-09-0007)

It was discovered that the HotPot module in Moodle did not correctly
filter SQL inputs. An authenticated remote attacker could execute
arbitrary SQL commands as the moodle database user, leading to a loss
of privacy or denial of service. (CVE-2008-6124, MSA-08-0010)

Kevin Madura discovered that the forum actions and messaging settings
in Moodle were not protected from cross-site request forgery (CSRF).
If an authenticated user were tricked into visiting a malicious
website while logged into Moodle, a remote attacker could change the
user's configurations or forum content. (CVE-2009-0499, MSA-09-0008,
MSA-08-0023)

Daniel Cabezas discovered that Moodle would leak usernames from the
Calendar Export tool. A remote attacker could gather a list of users,
leading to a loss of privacy. (CVE-2009-0501, MSA-09-0006)

Christian Eibl discovered that the TeX filter in Moodle allowed any
function to be used. An authenticated remote attacker could post a
specially crafted TeX formula to execute arbitrary TeX functions,
potentially reading any file accessible to the web server user,
leading to a loss of privacy. (CVE-2009-1171, MSA-09-0009)

Johannes Kuhn discovered that Moodle did not correctly validate user
permissions when attempting to switch user accounts. An authenticated
remote attacker could switch to any other Moodle user, leading to a
loss of privacy. (MSA-08-0003)

Hanno Boeck discovered that unconfigured Moodle instances contained
XSS vulnerabilities. An unauthenticated remote attacker could exploit
this to modify or steal confidential data of other users within the
same web domain. (MSA-08-0004)

Debbie McDonald, Mauno Korpelainen, Howard Miller, and Juan Segarra
Montesinos discovered that when users were deleted from Moodle, their
profiles and avatars were still visible. An authenticated remote
attacker could exploit this to store information in profiles even
after they were removed, leading to spam traffic. (MSA-08-0015,
MSA-09-0001, MSA-09-0002)

Lars Vogdt discovered that Moodle did not correctly filter certain
inputs. An authenticated remote attacker could exploit this to
generate XSS from which they could modify or steal confidential data
of other users within the same web domain. (MSA-08-0021)

It was discovered that Moodle did not correctly filter inputs for
group creation, mnet, essay question, HOST param, wiki param, and
others. An authenticated remote attacker could exploit this to
generate XSS from which they could modify or steal confidential data
of other users within the same web domain. (MDL-9288, MDL-11759,
MDL-12079, MDL-12793, MDL-14806)

It was discovered that Moodle did not correctly filter SQL inputs when
performing a restore. An attacker authenticated as a Moodle
administrator could execute arbitrary SQL commands as the moodle
database user, leading to a loss of privacy or denial of service.
(MDL-11857).
