CVE intelligence and bounded remediation
CVE-2023-31634 — In TeslaMate before 1.27.2, there is unauthorized access to port 4000 for remote viewing and operation of user data
In TeslaMate before 1.27.2, there is unauthorized access to port 4000 for remote viewing and operation of user data. After accessing the IP address for the TeslaMate instance, an attacker can switch the port to 3000 to enter Grafana for remote operations. At that time, the default username and password can be used to enter the Grafana management console without logging in, a related issue to CVE-2022-23126.

Authentication bypass and missing authentication
This catalog composition supplies bounded fallback guidance. Explicitly reviewed curated workflows load with the complete record below.
Check exposure
- Map every affected endpoint and protocol path, including alternate ports, legacy routes, recovery flows, service accounts, and machine-to-machine access.
- Confirm which deployments enable the affected authentication mode and whether the interface is reachable from untrusted networks.
- Review session, token, credential, and proxy trust configuration without attempting account takeover.
Remediate safely
- Apply the supported fix and centralize fail-closed authentication before protected request handling.
- Remove default or embedded credentials, rotate affected secrets and sessions, and bind authentication decisions to the intended audience and channel.
- Add negative tests for alternate routes, malformed or absent credentials, recovery flows, and proxy-derived identity.
