A XSS Vulnerability in /uploads/dede/action_search.php in DedeCMS V5.7 SP2 allows an authenticated user to execute remote arbitrary code via the keyword parameter.

DedeCMS V5.7 SP2 contains a CSRF vulnerability that allows a remote attacker to send a malicious request to to the web manager allowing remote code execution.

A Cross Site Scripting (XSS) issue was discovered in the search feature of DedeCMS v.5.8 that allows malicious users to inject code into web pages, and other users will be affected when viewing web pages.

A file upload issue exists in DeDeCMS before 5.7-sp1, which allows malicious users getshell.

In DedeCMS 5.7SP2, member/resetpassword.php allows remote authenticated users to reset the passwords of arbitrary users via a modified id parameter, because the key parameter is not properly validated.

In DedeCMS 5.7SP2, attackers can upload a .php file to the uploads/ directory (without being blocked by the Web Application Firewall), and then execute this file, via this sequence of steps: visiting the management page, clicking on the template, clicking on Default Template Management, clicking on New Template, and modifying the filename from ../index.html to ../index.php.

DedeCMS through V5.7SP2 allows arbitrary file upload in dede/album_edit.php or dede/album_add.php, as demonstrated by a dede/album_edit.php?dopost=save&formzip=1 request with a ZIP archive that contains a file such as "1.jpg.php" (because input validation only checks that .jpg, .png, or .gif is present as a substring, and does not otherwise check the file name or content).

uploads/include/dialog/select_soft.php in DedeCMS V57_UTF8_SP2 allows remote attackers to execute arbitrary PHP code by uploading with a safe file extension and then renaming with a mixed-case variation of the .php extension, as demonstrated by the 1.pHP filename.

An issue was discovered in DedeCMS V5.7 SP2. uploads/include/dialog/select_images_post.php allows remote attackers to upload and execute arbitrary PHP code via a double extension and a modified ".php" substring, in conjunction with the image/jpeg content type, as demonstrated by the filename=1.jpg.p*hp value.

DedeCMS 5.7 SP2 has SQL Injection via the dede\co_do.php ids parameter.
