Impact:
Exploitability:
CWE CWE-287
CAPEC
  • Authentication Abuse
    An attacker obtains unauthorized access to an application, service or device either through knowledge of the inherent weaknesses of an authentication mechanism, or by exploiting a flaw in the authentication scheme's implementation. In such an attack an authentication mechanism is functioning but a carefully controlled sequence of events causes the mechanism to grant access to the attacker. This attack may exploit assumptions made by the target's authentication procedures, such as assumptions regarding trust relationships or assumptions regarding the generation of secret values. This attack differs from Authentication Bypass attacks in that Authentication Abuse allows the attacker to be certified as a valid user through illegitimate means, while Authentication Bypass allows the user to access protected material without ever being certified as an authenticated user. This attack does not rely on prior sessions established by successfully authenticating users, as relied upon for the "Exploitation of Session Variables, Resource IDs and other Trusted Credentials" attack patterns.
  • Exploiting Trust in Client (aka Make the Client Invisible)
    An attack of this type exploits a programs' vulnerabilities in client/server communication channel authentication and data integrity. It leverages the implicit trust a server places in the client, or more importantly, that which the server believes is the client. An attacker executes this type of attack by placing themselves in the communication channel between client and server such that communication directly to the server is possible where the server believes it is communicating only with a valid client. There are numerous variations of this type of attack.
  • Utilizing REST's Trust in the System Resource to Register Man in the Middle
    This attack utilizes a REST(REpresentational State Transfer)-style applications' trust in the system resources and environment to place man in the middle once SSL is terminated. Rest applications premise is that they leverage existing infrastructure to deliver web services functionality. An example of this is a Rest application that uses HTTP Get methods and receives a HTTP response with an XML document. These Rest style web services are deployed on existing infrastructure such as Apache and IIS web servers with no SOAP stack required. Unfortunately from a security standpoint, there frequently is no interoperable identity security mechanism deployed, so Rest developers often fall back to SSL to deliver security. In large data centers, SSL is typically terminated at the edge of the network - at the firewall, load balancer, or router. Once the SSL is terminated the HTTP request is in the clear (unless developers have hashed or encrypted the values, but this is rare). The attacker can utilize a sniffer such as Wireshark to snapshot the credentials, such as username and password that are passed in the clear once SSL is terminated. Once the attacker gathers these credentials, they can submit requests to the web service provider just as authorized user do. There is not typically an authentication on the client side, beyond what is passed in the request itself so once this is compromised, then this is generally sufficient to compromise the service's authentication scheme.
  • Man in the Middle Attack
    This type of attack targets the communication between two components (typically client and server). The attacker places himself in the communication channel between the two components. Whenever one component attempts to communicate with the other (data flow, authentication challenges, etc.), the data first goes to the attacker, who has the opportunity to observe or alter it, and it is then passed on to the other component as if it was never intercepted. This interposition is transparent leaving the two compromised components unaware of the potential corruption or leakage of their communications. The potential for Man-in-the-Middle attacks yields an implicit lack of trust in communication or identify between two components.

    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.
