CVE-2024-1826
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 · uneditedA vulnerability has been found in code-projects Library System 1.0 and classified as critical. This vulnerability affects unknown code of the file Source/librarian/user/student/login.php. The manipulation of the argument username/password leads to sql injection. The attack can be initiated remotely. The exploit has been disclosed to the public and may be used. VDB-254614 is the identifier assigned to this vulnerability.
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 confidenceSQL injection vulnerability in the login.php file of Library System 1.0 allows remote attackers to inject malicious SQL queries through the username and password parameters, potentially bypassing authentication and gaining unauthorized access to the 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 the Library System installationLocate the Library System application in your environment. Check for a directory or application folder containing the 'login.php' file. Confirm the application name and version from any README, metadata, or installation files present.Affected if The installed application is Code Projects Library System version 1.0
-
Locate and inspect the login.php fileFind the login.php file within the Library System installation directory. Open the file and examine the authentication logic, specifically how the username and password parameters are handled in SQL queries.Affected if The login.php file exists and contains SQL query logic that processes username and/or password parameters without visible sanitization
-
Check for unsanitized SQL query constructionWithin login.php, search for SQL query strings that directly concatenate or interpolate user-supplied variables (such as $username, $password, or $_POST/$_GET arrays) into the query without using prepared statements, parameterized queries, or proper escaping functions.Affected if The code shows direct string concatenation of user input into SQL queries (e.g., "SELECT * FROM users WHERE username='" . $username . "'") rather than using prepared statements or binding parameters
-
Verify the application is network-accessibleConfirm that the Library System login.php is accessible over the network (HTTP/HTTPS). Check if the web server hosting the application is exposed and if the login page can be reached remotely.Affected if The login.php is accessible remotely without authentication restrictions, allowing external attackers to send malicious input
-
Compare your version to affected rangeReview any version documentation, changelogs, or application metadata to confirm the exact version number of your Library System installation.Affected if Your installed version is exactly 1.0 (Code Projects Library System)
You are affected if you are running Code Projects Library System version 1.0 and the login.php file contains SQL queries that directly incorporate username/password parameters without prepared statements or input sanitization.

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 dataImplement prepared statements/parameterized queries for all SQL queries, especially in authentication logic, and apply proper input validation and escaping for user-supplied credentials.
