Описание
A flaw was found in Cockpit. This vulnerability allows a remote attacker to achieve arbitrary command execution on the host by exploiting unsanitized user-controlled parameters within crafted links in the system logs user interface (UI). An attacker can inject shell metacharacters and command substitutions into these parameters, leading to the execution of arbitrary shell commands on the affected system. This could result in a complete system compromise.
Отчет
An Important arbitrary command execution flaw exists in Cockpit's system logs UI. This vulnerability allows a remote attacker to execute arbitrary commands on the host by exploiting unsanitized user-controlled parameters within crafted links. This impacts Red Hat Enterprise Linux systems where Cockpit is installed and accessible.
Меры по смягчению последствий
Mitigation for this issue is either not available or the currently available options don't meet the Red Hat Product Security criteria comprising ease of use and deployment, applicability to widespread installation base or stability. Operational risk reduction until fixes are available: restrict access to Cockpit to trusted networks/users only, and avoid opening untrusted crafted Cockpit URLs
