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.

    (Opera: Multiple vulnerabilities)
    
        Multiple vulnerabilities have been discovered in Opera:
        Opera does not restrict the ability of a framed web page to change
        the address associated with a different frame (CVE-2008-4195).
        Chris Weber (Casaba Security) discovered a Cross-site scripting
        vulnerability (CVE-2008-4196).
        Michael A. Puls II discovered
        that Opera can produce argument strings that contain uninitialized
        memory, when processing custom shortcut and menu commands
        (CVE-2008-4197).
        Lars Kleinschmidt discovered that Opera, when
        rendering an HTTP page that has loaded an HTTPS page into a frame,
        displays a padlock icon and offers a security information dialog
        reporting a secure connection (CVE-2008-4198).
        Opera does not
        prevent use of links from web pages to feed source files on the local
        disk (CVE-2008-4199).
        Opera does not ensure that the address
        field of a news feed represents the feed's actual URL
        (CVE-2008-4200).
        Opera does not check the CRL override upon
        encountering a certificate that lacks a CRL (CVE-2008-4292).
        Chris (Matasano Security) reported that Opera may crash if it is
        redirected by a malicious page to a specially crafted address
        (CVE-2008-4694).
        Nate McFeters reported that Opera runs Java
        applets in the context of the local machine, if that applet has been
        cached and a page can predict the cache path for that applet and load
        it from the cache (CVE-2008-4695).
        Roberto Suggi Liverani
        (Security-Assessment.com) reported that Opera's History Search results
        does not escape certain constructs correctly, allowing for the
        injection of scripts into the page (CVE-2008-4696).
        David
        Bloom reported that Opera's Fast Forward feature incorrectly executes
        scripts from a page held in a frame in the outermost page instead of
        the page the JavaScript URL was located (CVE-2008-4697).
        David
        Bloom reported that Opera does not block some scripts when previewing a
        news feed (CVE-2008-4698).
        Opera does not correctly sanitize
        content when certain parameters are passed to Opera's History Search,
        allowing scripts to be injected into the History Search results page
        (CVE-2008-4794).
        Opera's links panel incorrectly causes
        scripts from a page held in a frame to be executed in the outermost
        page instead of the page where the URL was located
        (CVE-2008-4795).
      
    Impact :
    
        These vulnerabilities allow remote attackers to execute arbitrary code,
        to run scripts injected into Opera's History Search with elevated
        privileges, to inject arbitrary web script or HTML into web pages, to
        manipulate the address bar, to change Opera's preferences, to determine
        the validity of local filenames, to read cache files, browsing history,
        and subscribed feeds or to conduct other attacks.
      
    Workaround :
    
        There is no known workaround at this time."

    descriptionThe Opera Team reports : Scripts are able to change the addresses of framed pages that come from the same site. Due to a flaw in the way that Opera checks what frames can be changed, a site can change the address of frames on other sites inside any window that it has opened. This allows sites to open pages from other sites, and display misleading information on them. Custom shortcut and menu commands can be used to activate external applications. In some cases, the parameters passed to these applications are not prepared correctly, and may be created from uninitialized memory.

    pages to link to feed source files on the user's computer. Suitable
    detection of JavaScript events and appropriate manipulation can
    unreliably allow a script to detect the difference between successful
    and unsuccessful subscriptions to these files, to allow it to discover
    if the file exists or not. In most cases the attempt will fail.
    
    It has been reported that when a user subscribes to a news feed using
    the feed subscription button, the page address can be changed. This
    causes the address field not to update correctly. Although this can
    mean that misleading information can be displayed in the address
    field, it can only leave the attacking page's address in the address
    bar, not a trusted third party address."
