Summary

The CentralNotice extension for MediaWiki before 1.19.9, 1.20.x before 1.20.8, and 1.21.x before 1.21.3 sets the Cache-Control header to cache session cookies when a user is autocreated, which allows remote attackers to authenticate as the created user.

Common Weakness Enumeration (CWE)

Common Attack Pattern Enumeration and Classification (CAPEC)

  • Session Credential Falsification through Forging
    An attacker creates a false but functional session credential in order to gain or usurp access to a service. Session credentials allow users to identify themselves to a service after an initial authentication without needing to resend the authentication information (usually a username and password) with every message. If an attacker is able to forge valid session credentials they may be able to bypass authentication or piggy-back off some other authenticated user's session. This attack differs from Reuse of Session IDs and Session Sidejacking attacks in that in the latter attacks an attacker uses a previous or existing credential without modification while, in a forging attack, the attacker must create their own credential, although it may be based on previously observed credentials.
  • Exploitation of Session Variables, Resource IDs and other Trusted Credentials
    Attacks on session IDs and resource IDs take advantage of the fact that some software accepts user input without verifying its authenticity. For example, a message queuing system that allows service requesters to post messages to its queue through an open channel (such as anonymous FTP), authorization is done through checking group or role membership contained in the posted message. However, there is no proof that the message itself, the information in the message (such group or role membership), or indeed the process that wrote the message to the queue are authentic and authorized to do so. Many server side processes are vulnerable to these attacks because the server to server communications have not been analyzed from a security perspective or the processes "trust" other systems because they are behind a firewall. In a similar way servers that use easy to guess or spoofable schemes for representing digital identity can also be vulnerable. Such systems frequently use schemes without cryptography and digital signatures (or with broken cryptography). Session IDs may be guessed due to insufficient randomness, poor protection (passed in the clear), lack of integrity (unsigned), or improperly correlation with access control policy enforcement points. Exposed configuration and properties files that contain system passwords, database connection strings, and such may also give an attacker an edge to identify these identifiers. The net result is that spoofing and impersonation is possible leading to an attacker's ability to break authentication, authorization, and audit controls on the system.
  • Accessing/Intercepting/Modifying HTTP Cookies
    This attack relies on the use of HTTP Cookies to store credentials, state information and other critical data on client systems. The first form of this attack involves accessing HTTP Cookies to mine for potentially sensitive data contained therein. The second form of this attack involves intercepting this data as it is transmitted from client to server. This intercepted information is then used by the attacker to impersonate the remote user/session. The third form is when the cookie's content is modified by the attacker before it is sent back to the server. Here the attacker seeks to convince the target server to operate on this falsified information.
  • Manipulating Opaque Client-based Data Tokens
    In circumstances where an application holds important data client-side in tokens (cookies, URLs, data files, and so forth) that data can be manipulated. If client or server-side application components reinterpret that data as authentication tokens or data (such as store item pricing or wallet information) then even opaquely manipulating that data may bear fruit for an Attacker. In this pattern an attacker undermines the assumption that client side tokens have been adequately protected from tampering through use of encryption or obfuscation.
  • Session Credential Falsification through Prediction
    This attack targets predictable session ID in order to gain privileges. The attacker can predict the session ID used during a transaction to perform spoofing and session hijacking.

"The remote Debian host is missing a security update. It is, therefore,
affected by multiple vulnerabilities in MediaWiki :

  - A cross-site scripting (XSS) vulnerability exists due to
    a failure to validate input before returning it to the
    user. An unauthenticated, remote attacker can exploit
    this, via specially crafted SVG files, to execute
    arbitrary script code in the user's browser session.
    (CVE-2013-2031)

  - A flaw exists in the password blocking mechanism due to
    two different tools being used to block password change
    requests, these being Special:PasswordReset and
    Special:ChangePassword, either of which may be bypassed
    by the method the other prevents. A remote attacker can
    exploit this issue to change passwords. (CVE-2013-2032)

  - Multiple flaws exist in Sanitizer::checkCss due to the
    improper sanitization of user-supplied input. An
    unauthenticated, remote attacker can exploit these to
    bypass the blacklist. (CVE-2013-4567, CVE-2013-4568)

  - A flaw exists due to multiple users being granted the
    same session ID within HTTP headers. A remote attacker
    can exploit this to authenticate as another random
    user. (CVE-2013-4572)

  - A cross-site scripting (XSS) vulnerability exists in the
    /includes/libs/XmlTypeCheck.php script due to improper
    validation of user-supplied input. An unauthenticated,
    remote attacker can exploit this, via a specially
    crafted XSL file, to execute arbitrary script code in
    the user's browser session. (CVE-2013-6452)

  - A flaw exists in the /includes/upload/UploadBase.php
    script due to a failure to apply SVG sanitization when
    XML files are read as invalid. An unauthenticated,
    remote attacker can exploit this to upload non-sanitized
    XML files, resulting in an unspecified impact.
    (CVE-2013-6453)

  - A stored cross-site (XSS) scripting vulnerability exists
    in the /includes/Sanitizer.php script due to a failure
    to properly validate the '-o-link' attribute before
    returning it to users. An unauthenticated, remote
    attacker can exploit this, via a specially crafted
    request, to execute arbitrary script code in the user's
    browser session. (CVE-2013-6454)

  - A flaw exists in the log API within the
    /includes/api/ApiQueryLogEvents.php script that allows
    an unauthenticated, remote attacker to disclose
    potentially sensitive information regarding deleted
    pages. (CVE-2013-6472)

  - Multiple flaws exist in the PdfHandler_body.php,
    DjVu.php, Bitmap.php, and ImageHandler.php scripts when
    DjVu or PDF file upload support is enabled due to
    improper sanitization of user-supplied input. An
    authenticated, remote attacker can exploit these, via
    the use of shell metacharacters, to execute execute
    arbitrary shell commands. (CVE-2014-1610)

  - A cross-site request forgery (XSRF) vulnerability exists
    in the includes/specials/SpecialChangePassword.php
    script due to a failure to properly handle a correctly
    authenticated but unintended login attempt. An
    unauthenticated, remote attacker, by convincing a user
    to follow a specially crafted link, can exploit this to
    reset the user's password. (CVE-2014-2665)");
