CWE-915

Description

In Canonical LXD versions 4.12 through 6.7, the doCertificateUpdate function in lxd/certificates.go does not validate the Type field when handling PUT/PATCH requests to /1.0/certificates/{fingerprint} for restricted TLS certificate users, allowing a remote authenticated attacker to escalate privileges to cluster admin.

Affected configurations

• canonical lxd (>= 4.12 <= 5.0.6) • canonical lxd (>= 5.21.0 <= 5.21.4) • canonical lxd (>= 6.0 <= 6.7)
