CVE-2026-16315
Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.
NVD · uneditedOMICRON StationGuard before version 4.10 contains a cryptographic timing side-channel vulnerability in the backend authentication mechanism that may allow an unauthenticated attacker to forge valid authentication credentials, bypass authentication and authorization, and impersonate legitimate clients. An attacker can gain full access to the system configuration, allowing modification, reset, or unauthorized alteration of system parameters.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
dbcve · scopedOMICRON StationGuard version 4.10
- 1. Identify the current installed version of OMICRON StationGuard by checking the system interface or running the product's version command.
- 2. If the current version is earlier than 4.10, plan the upgrade to version 4.10.
- 3. Obtain the version 4.10 or later release from official OMICRON distribution channels.
- 4. Follow OMICRON's standard upgrade procedure for StationGuard, which typically involves backing up the current configuration.
- 5. Apply the version 4.10 upgrade to the StationGuard installation.
- 6. After upgrading, verify the installation was successful and confirm the new version is 4.10 or later.
- 7. Test the authentication mechanism to confirm the timing side-channel vulnerability has been addressed.

There is no version to upgrade to and no patch to apply. Every affected install stays exposed until the vendor ships a fix — or somebody else builds one.
Free. We build fixes in the order the community asks for them — and we’ll tell you the moment this one lands.
We develop and verify an original fix where the vendor hasn’t, from $1,950. Deployed to your staging first — never straight to production.
