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.

A Cross-Site Request Forgery (CSRF) in Pluck CMS v4.7.15 allows attackers to delete arbitrary pages.

A Cross-Site Request Forgery (CSRF) in Pluck CMS v4.7.15 allows attackers to change the password of any given user by exploiting this feature leading to account takeover.

In Pluck 4.7.16, an admin user can use the theme upload functionality at /admin.php?action=themeinstall to perform remote code execution.

Missing SSL Certificate Validation issue exists in Pluck 4.7.15 in update_applet.php, which could lead to man-in-the-middle attacks.

In Pluck-4.7.15 admin background a remote command execution vulnerability exists when uploading files.

Zip Slip vulnerability in Pluck-CMS Pluck 4.7.15 allows an attacker to upload specially crafted zip files, resulting in directory traversal and potentially arbitrary code execution.

Session Fixation vulnerability in login.php in Pluck-CMS Pluck 4.7.15 allows an attacker to sustain unauthorized access to the platform. Because Pluck does not invalidate prior sessions after a password change, access can be sustained even after an administrator performs regular remediation attempts such as resetting their password.

An issue was discovered in Pluck 4.7.10-dev2. There is a CSRF vulnerability that can editpage via a /admin.php?action=editpage

In Pluck-4.7.10-dev2 admin background, a remote command execution vulnerability exists when uploading files.
