Exponent CMS before 2.3.7 does not properly restrict the types of files that can be uploaded, which allows remote attackers to conduct cross-site scripting (XSS) attacks and possibly have other unspecified impact as demonstrated by uploading a file with an .html extension, then accessing it via the elFinder functionality.
In framework/modules/navigation/controllers/navigationController.php in Exponent CMS v2.4.0 or older, the parameter "target" of function "DragnDropReRank" is directly used without any filtration which caused SQL injection. The payload can be used like this: /navigation/DragnDropReRank/target/1.
A Blind SQL Injection Vulnerability in Exponent CMS through 2.4.0, with the rerank array parameter, can lead to site database information disclosure and denial of service.
The Pixidou Image Editor in Exponent CMS prior to v2.3.9 patch 2 could be used to upload a malicious file to any folder on the site via a cpi directory traversal.
Exponent CMS before 2.3.9 is vulnerable to an attacker uploading a malicious script file using redirection to place the script in an unprotected folder, one allowing script execution.
Multiple cross-site scripting (XSS) vulnerabilities in Exponent CMS before 2.1.4 patch 6, 2.2.x before 2.2.3 patch 9, and 2.3.x before 2.3.1 patch 4 allow remote attackers to inject arbitrary web script or HTML via the (1) PATH_INFO, the (2) src parameter in a none action to index.php, or the (3) "First Name" or (4) "Last Name" field to users/edituser.
