A cross-site scripting (XSS) vulnerability has been identified in MODX prior to 3.1.0. The vulnerability allows authenticated users to upload SVG files containing malicious JavaScript code as profile images, which gets executed in victims' browsers when viewing the profile image.

Directory traversal in setup/processors/urlsearch.php (aka the search page of an unused processor) in MODX Revolution 2.5.7 might allow remote attackers to obtain system directory information.

The (1) update and (2) package-installation features in MODX Revolution 2.5.4-pl and earlier use http://rest.modx.com by default, which allows man-in-the-middle attackers to spoof servers and trigger the execution of arbitrary code by leveraging the lack of the HTTPS protection mechanism.

setup/templates/findcore.php in MODX Revolution 2.5.4-pl and earlier allows remote attackers to execute arbitrary PHP code via the corepath parameter.

setup/controllers/language.php in MODX Revolution 2.5.4-pl and earlier does not properly constrain the language parameter, which allows remote attackers to conduct Cookie-Bombing attacks and cause a denial of service (cookie quota exhaustion), or conduct HTTP Response Splitting attacks with resultant XSS, via an invalid parameter value.

setup/controllers/welcome.php in MODX Revolution 2.5.4-pl and earlier allows remote attackers to execute arbitrary PHP code via the configkey parameter to the setup/index.php?action=welcome URI.

The (1) update and (2) package-installation features in MODX Revolution 2.5.4-pl and earlier do not verify X.509 certificates from SSL servers, which allows man-in-the-middle attackers to spoof servers and trigger the execution of arbitrary code via a crafted certificate.

Multiple SQL injection vulnerabilities in MODX Revolution before 2.2.14 allow remote attackers to execute arbitrary SQL commands via the (1) session ID (PHPSESSID) to index.php or remote authenticated users to execute arbitrary SQL commands via the (2) user parameter to connectors/security/message.php or (3) id parameter to manager/index.php.

SQL injection vulnerability in modx.class.php in MODX Revolution 2.0.0 before 2.2.13 allows remote attackers to execute arbitrary SQL commands via unspecified vectors.

Cross-site scripting (XSS) vulnerability in manager/templates/default/header.tpl in ModX Revolution before 2.2.11 allows remote attackers to inject arbitrary web script or HTML via the "a" parameter.

MODX Revolution through v2.7.0-pl allows XSS via the User Photo field.

MODX Revolution through v2.7.0-pl allows XSS via a document resource (such as pagetitle), which is mishandled during an Update action, a Quick Edit action, or the viewing of manager logs.

MODX Revolution through v2.7.0-pl allows XSS via an extended user field such as a Container name or Attribute name.

MODX Revolution through v2.7.0-pl allows XSS via User Settings such as Description.

In MODX Revolution before 2.5.7, an attacker might be able to trigger XSS by injecting a payload into the HTTP Host header of a request. This is exploitable only in conjunction with other issues such as Cache Poisoning.

In MODX Revolution before 2.5.7, a user with resource edit permissions can inject an XSS payload into the title of any post via the pagetitle parameter to connectors/index.php.

In MODX Revolution before 2.5.7, a user with file upload permissions is able to execute arbitrary code by uploading a file with the name .htaccess.

In MODX Revolution before 2.5.7, an attacker is able to trigger Reflected XSS by injecting payloads into several fields on the setup page, as demonstrated by the databasetype parameter.

In MODX Revolution before 2.5.7, when PHP 5.3.3 is used, an attacker is able to include and execute arbitrary files on the web server due to insufficient validation of the action parameter to setup/index.php, aka directory traversal.

MODX Revolution v2.6.5-pl allows stored XSS via a Create New Media Source action.

In MODX Revolution 2.5.7, the "key" and "name" parameters in the System Settings module are vulnerable to XSS. A malicious payload sent to connectors/index.php will be triggered by every user, when they visit this module.

A stored web content injection vulnerability (WCI, a.k.a XSS) is present in MODX Revolution CMS version 2.5.6 and earlier. An authenticated user with permissions to edit users can save malicious JavaScript as a User Group name and potentially take control over victims' accounts. This can lead to an escalation of privileges providing complete administrative control over the CMS.

MODX Revolution version <=2.6.4 contains a Directory Traversal vulnerability in /core/model/modx/modmanagerrequest.class.php that can result in remove files. This attack appear to be exploitable via web request via security/login processor. This vulnerability appears to have been fixed in pull 13980.

Directory traversal vulnerability in manager/controllers/default/resource/tvs.php in MODx Revolution 2.0.2-pl, and possibly earlier, when magicquotesgpc is disabled, allows remote attackers to read arbitrary files via a .. (dot dot) in the classkey parameter. NOTE: some of these details are obtained from third party information.

Cross-site scripting (XSS) vulnerability in manager/index.php in MODx Revolution 2.0.2-pl allows remote attackers to inject arbitrary web script or HTML via the modhash parameter.

Cross-site scripting (XSS) vulnerability in manager/assets/fileapi/FileAPI.flash.image.swf in MODX Revolution 2.3.2-pl allows remote attackers to inject arbitrary web script or HTML via the callback parameter.

MODX Revolution 2.x before 2.2.15 does not include the HTTPOnly flag in a Set-Cookie header for the session cookie, which makes it easier for remote attackers to obtain potentially sensitive information via script access to this cookie.

Cross-site scripting (XSS) vulnerability in manager/index.php in MODX Revolution 2.x before 2.2.15 allows remote attackers to inject arbitrary web script or HTML via the contextkey parameter.

MODX Revolution 2.x before 2.2.15 allows remote attackers to bypass the cross-site request forgery (CSRF) protection mechanism by (1) omitting the CSRF token or via a (2) long string in the CSRF token parameter.

Cross-site scripting (XSS) vulnerability in manager/templates/default/header.tpl in MODX Revolution 2.3.1-pl and earlier allows remote attackers to inject arbitrary web script or HTML via the "a" parameter to manager/. NOTE: this issue exists because of a CVE-2014-2080 regression.
