CVE-2023-41523
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 · uneditedStudent Attendance Management System v1 was discovered to contain a SQL injection vulnerability via the emailAddress parameter at createClassTeacher.php.
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 confidenceStudent Attendance Management System v1 contains a SQL injection vulnerability in the createClassTeacher.php file. The emailAddress parameter is not properly sanitized before being used in SQL queries, allowing an attacker to inject malicious SQL code. This high-severity (CVSS 8.8) flaw could enable unauthorized database access, data exfiltration, or potentially remote code execution depending on database configuration.

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.
-
Verify the Student Attendance Management System versionLocate the application version identifier in the project files, typically in a README, version.php, or composer.json file, or check the download source for version 1.0Affected if The installed version is 1.0
-
Confirm createClassTeacher.php exists in the deploymentSearch the web root directory for the file createClassTeacher.php, which should be present in the application source codeAffected if The file createClassTeacher.php exists in the application directory
-
Inspect emailAddress parameter handling in createClassTeacher.phpOpen createClassTeacher.php and locate the code handling the emailAddress parameter; examine whether it is used directly in SQL queries without parameterized queries, prepared statements, or input sanitization functions such as mysqli_real_escape_string or PDO bindingAffected if The emailAddress parameter is concatenated directly into SQL queries without escaping or binding
-
Verify the application database connection is activeConfirm the application is configured with a database connection (MySQL/MariaDB) by checking the database configuration file for valid credentials and connection parametersAffected if The application has an active database connection that could be exploited through the SQL injection
You are affected if you are running Student Attendance Management System version 1.0 and the createClassTeacher.php file contains unsanitized emailAddress input used in dynamic SQL queries.
Generated from the published advisory. Verify against your own configuration.
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 dynamic SQL queries with parameterized queries or prepared statements in createClassTeacher.php, ensuring all user input is properly escaped or bound before database execution. Conduct a full code audit to identify similar SQL injection vulnerabilities in other files.
