ID CVE-2014-0483
Summary The administrative interface (contrib.admin) in Django before 1.4.14, 1.5.x before 1.5.9, 1.6.x before 1.6.6, and 1.7 before release candidate 3 does not check if a field represents a relationship between models, which allows remote authenticated users to obtain sensitive information via a to_field parameter in a popup action to an admin change form page, as demonstrated by a /admin/auth/user/?pop=1&t=password URI.

Impact:
Exploitability:
CWE CWE-264
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.
  • Manipulating Input to File System Calls
    An attacker manipulates inputs to the target software which the target software passes to file system calls in the OS. The goal is to gain access to, and perhaps modify, areas of the file system that the target software did not intend to be accessible.

    description Several vulnerabilities were discovered in Django, a high-level Python web development framework. The Common Vulnerabilities and Exposures project identifies the following problems : - CVE-2014-0480 Florian Apolloner discovered that in certain situations, URL reversing could generate scheme-relative URLs which could unexpectedly redirect a user to a different host, leading to phishing attacks. - CVE-2014-0481 David Wilson reported a file upload denial of service vulnerability. Django's file upload handling in its default configuration may degrade to producing a huge number of `os.stat()` system calls when a duplicate filename is uploaded. A remote attacker with the ability to upload files can cause poor performance in the upload handler, eventually causing it to become very slow. - CVE-2014-0482 David Greisen discovered that under some circumstances, the use of the RemoteUserMiddleware middleware and the RemoteUserBackend authentication backend could result in one user receiving another user's session, if a change to the REMOTE_USER header occurred without corresponding logout/login actions. - CVE-2014-0483 Collin Anderson discovered that it is possible to reveal any field's data by modifying the 'popup' and 'to_field' parameters of the query string on an admin change form page. A user with access to the admin interface, and with sufficient knowledge of model structure and the appropriate URLs, could construct popup views which would display the values of non-relationship fields, including fields the application developer had not intended to expose in such a fashion.

    NASL id DEBIAN_DLA-65.NASL
    description This update address an issue with reverse() generating external URLs; a denial of service involving file uploads; a potential session hijacking issue in the remote-user middleware; and a data leak in the administrative interface. http://www.freexian.com/services/debian-lts.html CVE-2014-0480 Django includes the helper function django.core.urlresolvers.reverse, typically used to generate a URL from a reference to a view function or URL pattern name. However, when presented with input beginning with two forward-slash characters (//), reverse() could generate scheme-relative URLs to other hosts, allowing an attacker who is aware of unsafe use of reverse() (i.e., in a situation where an end user can control the target of a redirect, to take a common example) to generate links to sites of their choice, enabling phishing and other attacks. To remedy this, URL reversing now ensures that no URL starts with two slashes (//), replacing the second slash with its URL encoded counterpart (%2F). This approach ensures that semantics stay the same, while making the URL relative to the domain and not to the scheme. CVE-2014-0481 In the default configuration, when Django's file upload handling system is presented with a file that would have the same on-disk path and name as an existing file, it attempts to generate a new unique filename by appending an underscore and an integer to the end of the (as stored on disk) filename, incrementing the integer (i.e., _1, _2, etc.) until it has generated a name which does not conflict with any existing file. An attacker with knowledge of this can exploit the sequential behavior of filename generation by uploading many tiny files which all share a filename; Django will, in processing them, generate ever-increasing numbers of os.stat() calls as it attempts to generate a unique filename. As a result, even a relatively small number of such uploads can significantly degrade performance. To remedy this, Django's file-upload system will no longer use sequential integer names to avoid filename conflicts on disk; instead, a short random alphanumeric string will be appended, removing the ability to reliably generate many repeatedly-conflicting filenames. CVE-2014-0482 Django provides a middleware -- django.contrib.auth.middleware.RemoteUserMiddleware -- and an authentication backend, django.contrib.auth.backends.RemoteUserBackend, which use the REMOTE_USER header for authentication purposes. In some circumstances, use of this middleware and backend could result in one user receiving another user's session, if a change to the REMOTE_USER header occurred without corresponding logout/login actions. To remedy this, the middleware will now ensure that a change to REMOTE_USER without an explicit logout will force a logout and subsequent login prior to accepting the new REMOTE_USER. CVE-2014-0483 Django's administrative interface, django.contrib.admin, offers a feature whereby related objects can be displayed for selection in a popup window. The mechanism for this relies on placing values in the URL and querystring which specify the related model to display and the field through which the relationship is implemented. This mechanism does perform permission checks at the level of the model class as a whole. This mechanism did not, however, verify that the specified field actually represents a relationship between models. Thus a user with access to the admin interface, and with sufficient knowledge of model structure and the appropriate URLs, could construct popup views which would display the values of non-relationship fields, including fields the application developer had not intended to expose in such a fashion. To remedy this, the admin interface will now, in addition to its normal permission checks, verify that the specified field does indeed represent a relationship, to a model registered with the admin, and will raise an exception if either condition is not true.
