CVE-2008-7138
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 · uneditedThe Manager in Eye-Fi 1.1.2 generates predictable snonce values based on the time of day, which allows remote attackers to bypass authentication and upload arbitrary images by guessing the snonce.
Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.
dbcve analysis · high confidenceThe Eye-Fi Manager version 1.1.2 uses time-of-day values to generate session nonces (snonce), making the authentication tokens predictable. Attackers can bypass authentication by guessing the snonce value and upload arbitrary images to the service.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.
dbcve checksWork through these to decide whether this CVE applies to you.
-
Confirm Eye-Fi Manager is installedLocate the Eye-Fi Manager application on the system. Check common installation directories such as C:\Program Files\Eye-Fi or C:\Program Files (x86)\Eye-Fi on Windows, or /Applications/Eye-Fi Manager on macOS. The application is typically bundled with the Eye-Fi card driver software.Affected if Eye-Fi Manager version 1.1.2 is found installed on the system
-
Determine installed version numberRight-click the Eye-Fi Manager executable (EyeFiManager.exe on Windows or Eye-Fi Manager.app on macOS), select Properties, and view the Version tab. Alternatively, open the application and look for About or Version information in the Help menu.Affected if The version displayed is exactly 1.1.2
-
Verify snonce implementation (if access to logs or config)If available, inspect application logs or configuration files for authentication session token patterns. The vulnerability manifests as snonce values that increment predictably based on system time rather than using cryptographic randomness.Affected if Session nonces follow a time-based predictable pattern instead of random values
A system is affected if Eye-Fi Manager version 1.1.2 is installed and the application uses time-of-day based session nonce generation for authentication.

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.
From vendor dataReplace time-based snonce generation with cryptographically secure random values (CSPRNG). If a patch is unavailable from the vendor, consider network segmentation to limit exposure to untrusted networks.
