CVE-2017-17727

DedeCMS through 5.8.1-beta contains a PHP code injection vulnerability in ShowMsg() where the HTTP Referer header is written into a DedeTemplate string and included. Unauthenticated attackers can send a crafted Referer to /plus/flink.php?dopost=save with an empty validation code to execute arbitrary PHP and system commands.

A command execution vulnerability in DedeCMS V5.7.118 in file_manage_control.php allows an attacker to execute arbitrary commands on the server.

Remote Code Execution vulnerability in DedeCMS through version 5.7.109 allows an attacker to execute arbitrary code via a crafted POST request to /dede/tpl.php.

DedeCMS v5.7.109 has an arbitrary file upload vulnerability in /dede/file_manage_control.php that allows attackers to execute arbitrary code by uploading a crafted PHP file.

DedeCMS through 5.7 is vulnerable to SQL Injection via the $_FILES superglobal in plus/recommend.php.

DedeCMS versions up to 5.7 are vulnerable to SQL Injection via the logo parameter in plus/flink_add.php.

DedeCMS before 5.7 contains a file inclusion vulnerability in plus/carbuyaction.php that allows remote unauthenticated attackers to control the include path by manipulating the uninitialized code parameter passed to require_once. Attackers can supply path traversal sequences ../../ to include arbitrary local files outside the intended payment directory, potentially achieving local file disclosure. Exploitation evidence was first observed by the Shadowserver Foundation on 2023-10-18.

A vulnerability was found in DedeCMS 5.7.118 affecting the common.inc.php::_RunMagicQuotes function in plus/ad_js.php of the Advertisement Rendering component. Manipulating the aid argument can lead to code injection, and the attack can be executed remotely.

A weakness was identified in DedeCMS up to 5.7.118 in the require_once function of dede/update_guide.php. Manipulating the vtime argument causes code injection. Remote exploitation is possible and the exploit has been made public.

DedeCMS 5.6 and 5.7 contains a reflected cross-site scripting vulnerability that allows unauthenticated attackers to inject script by supplying unsanitized input to the adminDirHand parameter. Attackers can send crafted GET requests to /include/dialog/config.php that close the generated script tag and inject JavaScript, which executes in the victim's browser.
