CWE-269

Description

An Improper Input Validation vulnerability exists in the user websocket handler of MAAS. An authenticated, unprivileged attacker can intercept a user.update websocket request and inject the is_superuser property set to true. The server improperly validates this input, allowing the attacker to self-promote to an administrator role. This results in full administrative control over the MAAS deployment.

Affected configurations

• canonical maas (>= 3.3.0 < 3.3.11) • canonical maas (>= 3.4.0 < 3.4.9) • canonical maas (>= 3.5.0 < 3.5.9) • canonical maas (>= 3.6.0 < 3.6.2)
