Vulnerabilities

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.

MODX Revolution through 2.8.3-pl allows remote authenticated administrators to execute arbitrary code by uploading an executable file, because the Uploadable File Types setting can be changed by an administrator.

A XML External Entity (XXE) vulnerability was discovered in the modRestServiceRequest component in MODX CMS 2.7.3 which can lead to an information disclosure or denial of service (DOS).

Evolution CMS 2.0.x allows XSS via a description and new category location in a template. NOTE: the vendor states that the behavior is consistent with the "access policy in the administration panel.

Fred MODX Revolution < 1.0.0-beta5 is affected by: Incorrect Access Control - CWE-648. The impact is: Remote Code Execution. The component is: assets/components/fred/web/elfinder/connector.php. The attack vector is: Uploading a PHP file or change data in the database. The fixed version is: https://github.com/modxcms/fred/commit/139cefac83b2ead90da23187d92739dec79d3ccd and https://github.com/modxcms/fred/commit/01f0a3d1ae7f3970639c2a0db1887beba0065246.

MODX Revolution Gallery 1.7.0 is affected by: CWE-434: Unrestricted Upload of File with Dangerous Type. The impact is: Creating file with custom a filename and content. The component is: Filtering user parameters before passing them into phpthumb class. The attack vector is: web request via /assets/components/gallery/connector.php.

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

Evolution CMS 1.4.x allows XSS via the manager/ search parameter.

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

MODX Revolution version <=2.6.4 contains a Incorrect Access Control vulnerability in Filtering user parameters before passing them into phpthumb class that can result in Creating file with custom a filename and content. This attack appear to be exploitable via Web request. This vulnerability appears to have been fixed in commit 06bc94257408f6a575de20ddb955aca505ef6e68.

MODX Revolution 2.6.3 has XSS.

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.

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.

MODX Revolution version 2.x - 2.5.6 is vulnerable to blind SQL injection caused by improper sanitization by the escape method resulting in authenticated user accessing database and possibly escalating privileges.

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.

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

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

Directory traversal in /connectors/index.php in MODX Revolution before 2.5.2-pl allows remote attackers to perform local file inclusion/traversal/manipulation via a crafted dir parameter, related to browser/directory/remove.
