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.

Compliance Impact

The SQL injection vulnerability in CodeAstro Leave Management System 1.0 allows unauthorized database access, data tampering, and sensitive information leakage. Such security breaches can lead to non-compliance with data protection regulations like GDPR and HIPAA, which require the protection of personal and sensitive data against unauthorized access and breaches.

Exploitation of this vulnerability could result in exposure or alteration of personal employee data managed by the system, potentially violating confidentiality and integrity requirements mandated by these standards.

Therefore, until mitigations such as prepared statements, strict input validation, and restricted database permissions are implemented, the system remains at risk of non-compliance with common data protection regulations.

Executive Summary

CVE-2026-11506 is a critical SQL injection vulnerability found in the CodeAstro Leave Management System version 1.0, specifically in the file /admin/search_staff_for_deletion.php.

The vulnerability occurs because the 'name' parameter is not properly validated, allowing attackers to inject malicious SQL queries.

This flaw enables remote attackers to manipulate the database by executing unauthorized SQL commands.

Impact Analysis

Exploiting this SQL injection vulnerability can lead to unauthorized database access and data tampering.

  • Leakage of sensitive information stored in the database.
  • Potential full system control by attackers.
  • Disruption of service availability.
Detection Guidance

This SQL injection vulnerability in the file /admin/search_staff_for_deletion.php can be detected by testing the 'name' parameter for SQL injection flaws.

Proof-of-concept payloads include boolean-based blind, time-based blind, and UNION query attacks.

  • Use tools like sqlmap to test the 'name' parameter for injection, e.g., sqlmap -u "http://target/LeaveManagement-PHP/admin/search_staff_for_deletion.php?name=test" --batch
  • Manually test by injecting SQL payloads such as ' OR 1=1-- or ' UNION SELECT NULL-- into the 'name' parameter and observe the response.
Mitigation Strategies

Immediate mitigation steps include implementing prepared statements with parameter binding to prevent SQL injection.

Enforce strict input validation on the 'name' parameter to ensure only expected input is accepted.

Restrict database user permissions to limit the impact of a potential exploit.

Conduct regular security audits to identify and fix similar vulnerabilities.
