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 · unedited
Spytech SpyAnywhere 1.50 allows remote attackers to gain administrator access via a single character in the "loginpass" field.

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 · moderate confidence

Spytech SpyAnywhere 1.50 contains a severe authentication bypass vulnerability where a remote attacker can gain administrator access by sending a single character in the 'loginpass' field, effectively circumventing the entire authentication mechanism.

MitigationUpgrade to a patched version of SpyAnywhere if available; otherwise, discontinue use of this legacy software and replace with a supported remote administration tool, supplemented by network segmentation and firewall rules to restrict access 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 checks

Work through these to decide whether this CVE applies to you.

  1. Identify if SpyAnywhere is installed
    Search for SpyAnywhere files on the system, check installed programs list, or look for processes named 'spyanywhere' or similar
    Affected if SpyAnywhere software is found running or installed on the system
  2. Confirm the exact version number
    Check the installed version through program properties, about dialog, or version file - look specifically for version 1.50
    Affected if The installed version is exactly 1.50 (Spytech Web Spyanywhere = 1.50)
  3. Check if the web administration interface is accessible
    Attempt to access the SpyAnywhere web interface on common ports (typically port 80/8080) or check firewall rules allowing external access to the service
    Affected if The SpyAnywhere web management console is network-accessible
  4. Verify the authentication mechanism exposure
    Review network exposure of the login page - the vulnerability is triggered by sending any single character to the 'loginpass' field
    Affected if The web login endpoint is reachable from a network perspective

The system is affected if Spytech Web Spyanywhere version 1.50 is installed and its web administration interface is network-accessible, allowing the authentication bypass to be exploited.
