Vulnerabilities

e107 CMS version 3.2.1 contains a file upload vulnerability that allows authenticated administrators to override server files through the Media Manager import functionality. Attackers can exploit the upload mechanism by manipulating the upload URL parameter to overwrite existing files like top.php in the web application directory.

A vulnerability was detected in e107 CMS up to 2.3.3. This impacts an unknown function of the file /e107_admin/image.php?mode=main&action=avatar of the component Avatar Handler. Performing manipulation of the argument multiaction[] results in path traversal. It is possible to initiate the attack remotely. The exploit is now public and may be used. The vendor was contacted early about this disclosure but did not respond in any way.

e107 CMS thru 2.3.3 are vulnerable to insecure deserialization in the `install.php` script. The script processes user-controlled input in the `previous_steps` POST parameter using `unserialize(base64_decode())` without validation, allowing attackers to craft malicious serialized data. This could lead to remote code execution, arbitrary file operations, or denial of service, depending on available PHP object gadgets in the codebase.

Multiple Cross Site Scripting (XSS) vulnerability in e017 CMS v.2.3.2 allows a local attacker to execute arbitrary code via a crafted script to the Copyright and Author fields in the Meta & Custom Tags Menu.

Cross Site Scripting vulnerability in e107 v.2.3.2 allows a remote attacker to execute arbitrary code via the description function in the SEO project.

usersettings.php in e107 through 2.3.0 lacks a certain e_TOKEN protection mechanism.

In e107 v2.1.7, output without filtering results in XSS.

An issue was discovered in e107 v2.1.9. There is a XSS attack on e107_admin/comment.php.

e107 2.1.2 allows PHP Object Injection with resultant SQL injection, because usersettings.php uses unserialize without an HMAC.

e107 2.1.9 allows CSRF via e107_admin/wmessage.php?mode=&action=inline&ajax_used=1&id= for changing the title of an arbitrary page.

e107_web/js/plupload/upload.php in e107 2.1.8 allows remote attackers to execute arbitrary PHP code by uploading a .php filename with the image/jpeg content type.

e107 2.1.8 has XSS via the e107_admin/users.php?mode=main&action=list user_loginname parameter.

e107 2.1.8 has CSRF in 'usersettings.php' with an impact of changing details such as passwords of users including administrators.

e107 2.1.7 has CSRF resulting in arbitrary user deletion.

e107 2.1.1 allows SQL injection by remote authenticated administrators via the pagelist parameter to e107_admin/menus.php, related to the menuSaveVisibility function.

e107 2.1.4 is vulnerable to cross-site request forgery in plugin-installing, meta-changing, and settings-changing. A malicious web page can use forged requests to make e107 download and install a plug-in provided by the attacker.
