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
While editing pages managed by MegaBIP a user with high privileges is prompted to give a reasoning for performing this action. Input provided by the the user is not sanitized, leading to SQL Injection vulnerability.  Version 5.20 of MegaBIP fixes this issue.

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 confidence

MegaBIP versions before 5.20 contain a SQL Injection vulnerability in the reasoning input field presented to high-privilege users when editing pages. The user-supplied reasoning text is not properly sanitized before being used in SQL queries, allowing an attacker with high privileges to inject malicious SQL statements.

MitigationUpgrade to MegaBIP version 5.20 or later. If immediate upgrade is not feasible, implement input validation and parameterized queries for all database interactions involving user-supplied content.

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. Determine MegaBIP version
    Locate and read the MegaBIP version information from your installation (typically found in the application header, About page, version file, or configuration file)
    Affected if The installed version is below 5.20 (for example, 5.19, 5.18, or earlier)
  2. Verify high-privilege accounts exist
    Check your user management system or database for accounts with elevated privileges (administrator, editor, or similar high-privilege roles)
    Affected if Any high-privilege user accounts are present in the system
  3. Confirm page editing feature is accessible
    Log in with a high-privilege account and navigate to the page editing functionality to verify the reasoning input field is present
    Affected if The page editing interface with the reasoning input field is accessible to high-privilege users
  4. Check database query handling
    Examine the application code or configuration related to the reasoning input field to determine if input is being sanitized or if parameterized queries are used
    Affected if User-supplied reasoning text is used directly in SQL queries without sanitization or parameterization

Your environment is affected if you are running MegaBIP version below 5.20, high-privilege users have access to the page editing feature with a reasoning input field, and that field is not sanitized before SQL execution.

Mitigation available No clean upgrade yet — mitigate in the meantime
Mitigation

Upgrade to MegaBIP version 5.20 or later. If immediate upgrade is not feasible, implement input validation and parameterized queries for all database interactions involving user-supplied content.

Recommended fix Moderate confidence

Version 5.20

  1. 1. Back up the current MegaBIP installation and database before proceeding with any upgrade.
  2. 2. Download MegaBIP version 5.20 from the official vendor source (megabip.pl).
  3. 3. Install version 5.20 as a fresh installation or upgrade existing installation following vendor documentation.
  4. 4. Verify the upgrade was successful by accessing the MegaBIP admin interface.
  5. 5. Test that the reasoning input field when editing pages properly sanitizes user input (no raw SQL injection possible).
  6. 6. Confirm all other MegaBIP functionalities remain operational after the upgrade.
