Vulnerability Title
Cockpit: cockpit: arbitrary command execution via crafted links in system logs ui
Source: CVE Program / CVE List V5
Vulnerability Description
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.
