Detailsinfo

A vulnerability, which was classified as critical, was found in Notifiarr dockwatch up to 0.6.567. This affects the function exit of the file loader.php of the component POST Parameter Handler. The manipulation of the argument composePath with an unknown input leads to a redirect vulnerability. CWE is classifying the issue as CWE-698. The web application sends a redirect to another location, but instead of exiting, it executes additional code. This is going to have an impact on confidentiality, integrity, and availability. The summary by CVE is:

Dockwatch through 0.6.567 contains an unauthenticated OS command injection vulnerability that allows remote attackers to execute arbitrary shell commands by exploiting a missing exit() after an authentication redirect in loader.php combined with unsanitized input passed to shell_exec() in ajax/compose.php. Attackers can seed the required session flag through the incomplete auth check, then inject arbitrary commands via the composePath POST parameter in the composePull action to achieve full host compromise, facilitated by the standard deployment mounting of the Docker socket.
