Description

This security bulletin contains information about 3 vulnerabilities.


1) Resource exhaustion (CVE-ID: CVE-2024-21651)

The vulnerability allows a remote attacker to cause a denial of service.

The vulnerability exists due to uncontrolled resource consumption in the attachment parsing functionality when processing a malformed TAR attachment with manipulated file modification time headers through Tika. A remote attacker can upload a specially crafted TAR file to cause a denial of service.

Exploitation requires the ability to attach a file to a page.


2) Eval Injection (CVE-ID: CVE-2024-21650)

The vulnerability allows a remote attacker to execute arbitrary code.

The vulnerability exists due to improper neutralization of directives in dynamically evaluated code in the user registration feature when processing user-supplied "first name" or "last name" fields during registration. A remote attacker can submit crafted registration data to execute arbitrary code.

Only installations that have user registration enabled for guests are vulnerable.


3) Improper Handling of Insufficient Privileges (CVE-ID: CVE-2024-21648)

The vulnerability allows a remote user to gain rights they do not have anymore.

The vulnerability exists due to improper handling of insufficient privileges in the rollback action when performing a page rollback. A remote user can roll back a page to a previous version to gain rights they do not have anymore.

User interaction is required.
