CVE-2021-37787
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 unprivileged administrative interface in ABO.CMS version 5.8 through v.5.9.3 is affected by a SQL Injection vulnerability via a HTTP POST request to the TinyMCE module
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 confidenceSQL Injection vulnerability in the TinyMCE module of ABO.CMS versions 5.8 through 5.9.3, exploitable via HTTP POST requests to the unprivileged administrative interface. The vulnerability allows injection of malicious SQL queries through unsanitized input parameters.

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 ABO.CMS installationLocate ABO.CMS by checking web root directories for the characteristic folder structure, configuration files, or login pages branded as ABO.CMS. Common indicators include admin login forms or CMS-specific directories.Affected if ABO.CMS is present on the server
-
Determine the installed versionLocate the version file or header within the ABO.CMS installation. Check version information typically found in the CMS admin panel, a VERSION file, or the main configuration file.Affected if The installed version is >= 5.8 and <= 5.9.3
-
Verify TinyMCE module is enabledCheck if the TinyMCE WYSIWYG editor module is loaded or accessible within the CMS. This may be visible in the admin panel features, module listings, or by checking which editors are available when editing content.Affected if TinyMCE module is installed and enabled in the CMS configuration
-
Confirm admin interface accessibilityTest access to the administrative interface via HTTP/HTTPS. The vulnerability is exploitable through POST requests to the unprivileged admin interface.Affected if The administrative interface is reachable over the network (even if behind authentication)
-
Inspect HTTP logs for SQL injection patternsReview web server access logs and application logs for POST requests to TinyMCE-related endpoints containing suspicious SQL syntax such as UNION, SELECT, DROP, or common injection payloads in parameter values.Affected if Suspicious SQL injection patterns are found in logs targeting TinyMCE endpoints
A system is affected if it runs ABO.CMS versions 5.8 through 5.9.3 with the TinyMCE module enabled and the admin interface accessible, and especially if logs show SQL injection attempts.

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 dataUpgrade to a patched version of ABO.CMS. If no patch is available, disable or remove the TinyMCE module until a fix can be implemented. Implement parameterized queries or input validation as an interim control.
