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.
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.
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.
