Vulnerabilities in this advisory
- CVE-2022-33137 — CVE-2022-33137 · CWE-613
The web session management of affected devices does not invalidate session ids in certain logout scenarios. This could allow an authenticated remote attacker to hijack other users' sessions.
- CVE-2022-33138 — CVE-2022-33138 · CWE-306
Affected devices do not perform authentication for several web API endpoints. This could allow an unauthenticated remote attacker to read and download data from the device.
