CVE-2020-8657
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 · uneditedAn issue was discovered in EyesOfNetwork 5.3. The installation uses the same API key (hardcoded as EONAPI_KEY in include/api_functions.php for API version 2.4.2) by default for all installations, hence allowing an attacker to calculate/guess the admin access token.
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 confidenceEyesOfNetwork 5.3 uses a hardcoded API key (EONAPI_KEY) in include/api_functions.php that is identical across all installations. Since the default key is known, attackers can calculate or guess the admin access token to gain full administrative access to the system.

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.
-
Identify Eyesofnetwork installation versionRun 'dpkg -l eyesofnetwork' or check the package management system for the installed version of EyesofnetworkAffected if Version is exactly 5.3-0
-
Locate the api_functions.php fileFind include/api_functions.php in the Eyesofnetwork web root directory (typically under /opt/eyesofnetwork or /var/www/html)Affected if The file exists in the expected location
-
Inspect for hardcoded EONAPI_KEYOpen include/api_functions.php and search for the string 'EONAPI_KEY' or 'define(' and examine any API key definitionsAffected if A hardcoded EONAPI_KEY value is present in the code
-
Verify API functionality is accessibleCheck if the Eyesofnetwork API endpoints are exposed (typically at /api/ or /api/v1/ paths) and accessible from the networkAffected if API endpoints are reachable without authentication or with the hardcoded key
-
Audit for unauthorized admin accessReview Eyesofnetwork admin user accounts and check access logs for administrative actions performed using API tokensAffected if Unexpected admin accounts exist or administrative actions were performed via API with unknown origin
The environment is affected if running Eyesofnetwork 5.3-0 with the hardcoded EONAPI_KEY present in include/api_functions.php and the API is network-accessible

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 dataGenerate a unique, cryptographically secure API key for each installation and update the configuration. Rotate any exposed credentials and ensure the new key is stored securely rather than hardcoded.
