CVE-2020-23936
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 · uneditedPHPGurukul Vehicle Parking Management System 1.0 is vulnerable to Authentication Bypass via "Username: admin'# && Password: (Write Something)".
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 confidenceThe Vehicle Parking Management System 1.0 contains a SQL injection vulnerability in the login authentication mechanism. By supplying a specially crafted username value of "admin'#", an attacker can terminate the SQL query prematurely and comment out the password verification portion, allowing authentication as admin without knowing the password. This is a classic authentication bypass via SQL injection.

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.
-
Confirm product and versionIdentify the installed Vehicle Parking Management System and check if it is version 1.0. Look for version identifiers in the application source files, about page, or any documentation.Affected if The installed version is Phpgurukul Vehicle Parking Management System version 1.0 exactly.
-
Locate the login authentication fileFind the PHP file that handles the login process. Common locations include login.php, index.php in the root or an admin/ folder. Search for files that process username and password form submissions.Affected if A login.php or equivalent authentication file exists that processes user credentials.
-
Inspect SQL query construction in login codeOpen the login processing file and examine the SQL query used for authentication. Look for the query that validates username and password against a database. Check if user input (from $_POST['username'] or similar) is directly concatenated or interpolated into the SQL string.Affected if The SQL query is built by directly concatenating or interpolating user input without using parameterized queries or prepared statements.
-
Test for SQL injection vulnerabilityOn the login form, enter 'admin'# (without quotes) as the username and any arbitrary password. Submit the form and observe if authentication succeeds as the admin user.Affected if The login succeeds with the username 'admin'# and any password, indicating the SQL injection allows authentication bypass.
Your environment is affected if you are running Phpgurukul Vehicle Parking Management System version 1.0 and the login authentication code constructs SQL queries by directly embedding user input without parameterized queries.

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 dataReplace the vulnerable SQL query with parameterized queries (prepared statements) to properly separate code from data, ensuring user input is never interpreted as SQL commands. Additionally, implement input validation and apply any available vendor patches.
