CVE-2020-25147
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 Observium Professional, Enterprise & Community 20.8.10631. It is vulnerable to SQL Injection due to the fact that it is possible to inject malicious SQL statements in malformed parameter types. This can occur via username[0] to the default URI, because of includes/authenticate.inc.php.
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 confidenceSQL Injection vulnerability in Observium authentication (includes/authenticate.inc.php) allows remote attackers to inject malicious SQL statements via the username[0] parameter using array notation, enabling potential authentication bypass and database compromise.

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 Observium installation locationLocate the Observium web application directory, typically found in /var/www/observium or /opt/observium. Look for the main index.php or the includes/ directory.Affected if Observium is installed and the includes/authenticate.inc.php file exists in the webroot.
-
Determine installed Observium versionCheck the version file or database: look for a VERSION file in the installation root, or query the database for the version information. Compare against version 20.8.10631.Affected if The installed version matches 20.8.10631 exactly.
-
Verify vulnerable authentication file existsConfirm that includes/authenticate.inc.php exists in the Observium installation directory and is readable by the web server.Affected if The file includes/authenticate.inc.php is present and contains authentication logic that processes the username parameter.
-
Check remote authentication exposureDetermine if the Observium login page (typically at / or /login) is accessible from remote network locations. Review web server configuration or firewall rules for exposed authentication endpoints.Affected if The Observium authentication interface is accessible from untrusted networks, enabling remote attackers to send malicious requests.
A defender is affected if they have Observium version 20.8.10631 installed with the authenticate.inc.php file present and the login page exposed to remote access, allowing injection through the username[0] parameter.

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 dataFix parameter handling in includes/authenticate.inc.php to properly sanitize/validate the username parameter and prevent SQL injection, followed by comprehensive testing to ensure authentication still functions correctly.
