Pluck CMS - CSRF via Spoofable Missing-Referer Bypass Leads to Stored XSS and RCE

Pluck CMS's admin panel relies solely on a Referer-header comparison (requestedByTheSameDomain in data/inc/functions.admin.php, gating every admin.php action) for CSRF protection, with no per-request anti-CSRF token anywhere in the admin area.

Pluck CMS - Unrestricted File Upload via Missing .php8 Extension in Upload Blacklist

Pluck CMS through 4.7.21 restricts dangerous file uploads in its admin file-management feature using a fixed blacklist in data/inc/files.php ('.php','php3','php4','php5','php6','php7','phtml','.phtm','.pht','.ph3','.ph4','.ph5','.asp','.cgi','.phar'), checked against the last 4-5 characters of the filename.

Stored XSS in Pluck CMS Page Editor Enabling Privilege Escalation

Cross Site Scripting vulnerability in Pluck CMS before v.4.7.21dev allows a remote attacker to escalate privileges via the editpage.php and the sanitizePageContent function

Directory traversal vulnerability in data/inc/lib/pcltar.lib.php in Pluck 4.5.3, when register_globals is enabled, allows remote attackers to include and execute arbitrary local files via directory traversal sequences in the g_pcltar_lib_dir parameter.

Multiple directory traversal vulnerabilities in pluck 4.6.2, when register_globals is enabled, allow remote attackers to include and execute arbitrary local files via a .. (dot dot) in the langpref parameter to (1) data/modules/contactform/module_info.php, (2) data/modules/blog/module_info.php, and (3) data/modules/albums/module_info.php, different vectors than CVE-2008-3194.

Directory traversal vulnerability in data/modules/blog/module_pages_site.php in Pluck 4.6.1 allows remote attackers to include and execute arbitrary local files via a .. (dot dot) in the post parameter.

An incorrect limitation of a path to a restricted directory (path traversal) has been detected in Pluck CMS, affecting version 4.7.18. An unauthenticated attacker could extract sensitive information from the server via the absolute path of a file located in the same directory or subdirectory as the module, but not from recursive directories.

In Pluck CMS 4.7.20-dev, an authenticated attacker can upload or create a crafted PHP file under the albums module directory and access it via the module routing logic in albums.site.php, resulting in arbitrary command execution through a GET parameter.

Pluck CMS 4.7.2 allows remote attackers to execute arbitrary code via the blog form feature.

Cross-site scripting (XSS) vulnerability in TinyMCE in Pluck CMS 4.7.2 allows remote authenticated users to inject arbitrary web script or HTML via the "edit HTML source" option.

Pluck CMS 4.7.2 allows remote attackers to obtain sensitive information by (1) changing "PHPSESSID" to an array; (2) adding non-alphanumeric chars to "PHPSESSID"; (3) changing the image parameter to an array; or (4) changing the image parameter to a string, which reveals the installation path in an error message.

A file upload restriction bypass vulnerability in Pluck CMS before 4.7.13 allows an admin privileged user to gain access in the host through the "manage files" functionality, which may result in remote code execution.

File Upload vulnerability in PluckCMS v.4.7.10 allows a remote attacker to execute arbitrary code via the trashcan_restoreitem.php file.

Multiple cross-site request forgery (CSRF) vulnerabilities in admin.php in pluck 4.7 allow remote attackers to hijack the authentication of admins for requests that (1) modify the admin email address or (2) modify the blog title via a settings action; (3) add a page via an editpage action, or (4) add a categorie via the blog module.

Pluck CMS 4.7.18 does not restrict failed login attempts, allowing attackers to execute a brute force attack.

Authenticate Remote Code Execution in Pluck CMS

Pluck CMS is vulnerable to an authenticated remote code execution (RCE) vulnerability through its “albums” module. Albums are used to create collections of images that can be inserted into web pages across the site. Albums allow the upload of various filetypes, which undergo a normalization process before being available on the site. Due to lack of file extension validation, it is possible to upload a crafted JPEG payload containing an embedded PHP web-shell. An attacker may navigate to it directly to achieve RCE on the underlying web server. Administrator credentials for the Pluck CMS web interface are required to access the albums module feature, and are thus required to exploit this vulnerability. CVSS:3.1/AV:N/AC:L/PR:H/UI:N/S:C/C:H/I:H/A:H/E:P/RL:O/RC:C (8.2 High)

File upload vulnerability in Pluck CMS v.4.7.10-dev2 allows a remote attacker to execute arbitrary code and access sensitive information via the theme.php file.

An issue discovered in Pluck CMS v.4.7.10-dev2 allows a remote attacker to execute arbitrary php code via the hidden parameter to admin.php when editing a page.

File Upload vulnerability in PluckCMS v.4.7.10 dev versions allows a remote attacker to execute arbitrary code via a crafted image file to the the save_file() parameter.

An issue discovered in /admin.php in Pluck CMS 4.7.15 through 4.7.16-dev5 allows remote attackers to run arbitrary code via manage file functionality.
