Exploitation vector: Network

Exploit availability: No

Vulnerable software:
Octopus Deploy
Server applications / Application servers

Vendor: Octopus Deploy

Description

The vulnerability allows a remote authenticated user to execute arbitrary code.

In Octopus Deploy before 4.1.3, the machine update process doesn't check that the user has access to all environments. This allows an access-control bypass because the set of environments to which a machine is scoped may include environments in which the user lacks access.

Mitigation
Install update from vendor's website.

Vulnerable software versions

Octopus Deploy: 4.1.0 - 4.1.2
