CVE-2023-37268 — Warpgate is an SSH, HTTPS and MySQL bastion host for Linux that doesn't need special client apps

High CVSS 8.8

Warpgate is an SSH, HTTPS and MySQL bastion host for Linux that doesn't need special client apps. When logging in as a user with SSO enabled an attacker may authenticate as an other user. Any user account which does not have a second factor enabled could be compromised. This issue has been addressed in commit `8173f6512a` and in releases starting with version 0.7.3. Users are advised to upgrade. Users unable to upgrade should require their users to use a second factor in authentication.

Matched remediation archetype

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.
