CVE-2020-11812
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 · uneditedRukovoditel 2.5.2 is affected by a SQL injection vulnerability because of improper handling of the filters[0][value] or filters[1][value] parameter.
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 confidenceRukovoditel 2.5.2 contains a SQL injection vulnerability in the filters[0][value] and filters[1][value] parameters. An unauthenticated attacker can inject malicious SQL queries through these parameters to manipulate database queries, potentially gaining unauthorized access to sensitive data or compromising the underlying 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 installed Rukovoditel versionLocate the version number by checking the application footer, about page, or version file in the web root directory. Alternatively, check the HTTP response headers or any version.php/configuration file if accessible.Affected if The installed version is exactly 2.5.2
-
Confirm filter functionality is accessibleNavigate to any list view or reporting feature within the application that utilizes filtering. The vulnerable parameters filters[0][value] and filters[1][value] are used in filter search functionality.Affected if The application exposes filter/search functionality that processes these parameter names
-
Test parameter processingSubmit a request to an endpoint that accepts filter parameters (typically list views or reports) with filters[0][value]=test and filters[1][value]=test. Check if the application processes these without immediate error or validation rejection.Affected if The application accepts and processes filter parameters in the URL or POST data
-
Verify database user privilegesInspect the database configuration file (commonly config.php or database.php in the application root) to determine what database credentials the application uses.Affected if The database user has broad privileges beyond what the application functionality requires (such as WRITE to arbitrary tables, FILE privilege, or administrative access)
You are affected if running Rukovoditel version 2.5.2 and the filter functionality processes parameters filters[0][value] and filters[1][value] without SQL injection protection.

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 by implementing parameterized queries or prepared statements for all filter parameter handling, apply input validation and sanitization, and restrict database user privileges to the minimum required.
