CVE-2015-3637
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 · uneditedSQL injection vulnerability in phpMyBackupPro when run in multi-user mode before 2.5 allows remote attackers to execute arbitrary SQL commands via the username and password parameters.
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 phpMyBackupPro's multi-user authentication mechanism allows remote attackers to execute arbitrary SQL commands via the username and password parameters. The vulnerability exists in versions prior to 2.5 and stems from unsanitized user input being directly concatenated into SQL queries during the login process.

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.
-
Locate phpMyBackupPro installationSearch for phpMyBackupPro files on the web server, typically in document root directories such as /var/www/html, /www, or similar paths. Look for the main PHP files like index.php, login.php, or a folder named 'phpMyBackupPro'.Affected if phpMyBackupPro is present on the server and the version cannot be determined or is below 2.5
-
Determine installed versionOpen the main configuration file (usually config.php or version.php in the phpMyBackupPro directory) and look for a version variable or string. Common patterns include lines containing '$version', 'VERSION', or 'version ='. Compare the found version number to 2.5.Affected if The version number is less than 2.5 or no version file is found (indicating an old installation)
-
Check if multi-user mode is enabledExamine the configuration file for multi-user settings. Look for parameters like '$CONF[multiuser]', '$multi_user_mode', or similar. Also check for a 'users.php' or 'users.txt' file in the installation directory which stores multi-user credentials.Affected if Multi-user mode is enabled in the configuration or user definition files exist
-
Identify the login processing scriptLocate the login processing file (typically login.php, auth.php, or similar). Open it and inspect the SQL query construction for the authentication logic. Look for direct concatenation of $_POST['username'] or $_POST['password'] variables into SQL queries without using prepared statements or escaping functions.Affected if The login script contains SQL queries that concatenate user input directly without sanitization
-
Test if the login page accepts unauthenticated requestsAccess the phpMyBackupPro login page directly via web browser or curl. Confirm the page loads without requiring prior authentication. This confirms the vulnerable authentication endpoint is exposed.Affected if The login page is accessible without authentication and the application uses the multi-user authentication mechanism
The environment is affected if phpMyBackupPro version is below 2.5 AND multi-user mode is enabled, exposing an unauthenticated SQL injection vulnerability in the login processing logic.

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 data2.5
Upgrade phpMyBackupPro to version 2.5 or later which contains the fix for this SQL injection vulnerability. As a temporary workaround, disable multi-user mode if operationally feasible.
