CWE ID Description
CWE-89 The product constructs all or part of an SQL command using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify the intended SQL command when it is sent to a downstream component. Without sufficient removal or quoting of SQL syntax in user-controllable inputs, the generated SQL query can cause those inputs to be interpreted as SQL instead of ordinary user data.
CWE-74 The product constructs all or part of a command, data structure, or record using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify how it is parsed or interpreted when it is sent to a downstream component.

Executive Summary

CVE-2026-15523 is a SQL injection vulnerability found in the Simple Online Leave Management System version 1.0, specifically in the file /SimpleOnlineLeave/admin/dashboard.php. The issue arises from insufficient input validation of the 'name' parameter, which allows an attacker to inject malicious SQL code into database queries.

Impact Analysis

This vulnerability can have serious impacts including unauthorized access to the database, leakage of sensitive data, tampering with data, gaining control over the system, and causing service interruptions.

Detection Guidance

This vulnerability can be detected by monitoring for unusual or suspicious SQL queries involving the 'name' parameter in the /SimpleOnlineLeave/admin/dashboard.php file. One approach is to test the input validation by sending crafted payloads to the 'name' parameter and observing if SQL errors or unexpected behavior occurs.

For detection, you can use commands or tools that test for SQL injection vulnerabilities, such as using curl or sqlmap.

  • Using curl to test for SQL injection: curl -G 'http://target/SimpleOnlineLeave/admin/dashboard.php' --data-urlencode "name=' OR '1'='1"
  • Using sqlmap to automate detection: sqlmap -u "http://target/SimpleOnlineLeave/admin/dashboard.php?name=test" --batch

Additionally, monitoring logs for SQL errors or unusual database activity related to the 'name' parameter can help detect exploitation attempts.

Mitigation Strategies

Immediate mitigation steps include implementing prepared statements and strict input validation on the 'name' parameter to prevent SQL injection.

Additionally, minimize database user permissions to limit the impact of a potential exploit.

Conduct regular security audits to identify and address similar vulnerabilities.

Compliance Impact

The SQL injection vulnerability in the Simple Online Leave Management System 1.0 can lead to unauthorized database access, data leakage, and data tampering.

Such unauthorized access and potential exposure or alteration of sensitive data can negatively impact compliance with common standards and regulations like GDPR and HIPAA, which require protection of personal and sensitive information.

Failure to prevent such vulnerabilities may result in violations of data protection requirements, leading to legal and regulatory consequences.
