Summary

A SQL injection vulnerability in the EmployeeRecruitmentSystem registration handler allows remote attackers to manipulate database queries through insufficiently controlled input.

Exploitation may expose, alter, or delete database records when the affected registration functionality is reachable and attacker-controlled values are incorporated into SQL statements.

A SQL injection vulnerability in the EmployeeRecruitmentSystem registration handler allows remote attackers to manipulate database queries through insufficiently controlled input.

Exploitation may expose, alter, or delete database records when the affected registration functionality is reachable and attacker-controlled values are incorporated into SQL statements.

Affected context

The vulnerability occurs in the Registration Handler, specifically the mysql_query usage in source/adminregister.php. It affects deployments based on the identified unsupported code lineage where request-derived data may reach database queries without adequate parameterization or validation. Risk is greater when the registration endpoint is remotely accessible and the database account has broad privileges.

Risk is greater when the registration endpoint is remotely accessible and the database account has broad privileges.

Exploit preconditions

  • Attack surface: Remotely reachable registration functionality
  • Required access: Typically no authenticated access if the affected handler is publicly available
  • Trigger point: Processing attacker-controlled input in source/adminregister.php
  • Why exploitation is possible: Input may be incorporated into SQL statements without reliable separation between data and query syntax
  • Attack surface: Remotely reachable registration functionality
  • Required access: Typically no authenticated access if the affected handler is publicly available
  • Trigger point: Processing attacker-controlled input in source/adminregister.php
  • Why exploitation is possible: Input may be incorporated into SQL statements without reliable separation between data and query syntax

Why this happens

The underlying bug is an improper boundary between untrusted input and SQL command construction. When application data is concatenated into queries or passed through legacy query interfaces without parameterized binding, an attacker may influence the structure or behavior of the resulting statement.

This maps primarily to CWE-89: Improper Neutralization of Special Elements used in an SQL Command (SQL Injection). The broader CWE-74 classification reflects the unsafe handling of externally influenced command syntax.

Potential impact

  • An attacker may read sensitive database records
  • Database contents could be modified or deleted
  • Authentication or authorization data could be manipulated
  • The application may experience denial of service
  • A compromised database account could enable further access to connected systems

General mitigation guidance

Mitigation generally centers on separating data from SQL syntax and reducing trust in request-derived values.

Common defensive patterns include:

  • Use parameterized queries or prepared statements for all database operations
  • Apply allowlist validation for fields with constrained formats
  • Avoid dynamically assembled SQL where structured query APIs are available
  • Give the application database account only the permissions it requires
  • Protect administrative and registration endpoints with appropriate access controls and rate limits
  • Centralize database access patterns so unsafe query construction is less likely to recur
  • Treat unsupported application code as a heightened maintenance and assurance risk

How teams detect issues like this

Organizations can look for SQL injection risk through:

  • Static analysis rules identifying string concatenation or interpolation in SQL calls
  • Code review checks for legacy query APIs such as direct mysql_query usage
  • Tests using benign metacharacter and boundary inputs to verify parameter handling
  • Web application firewall or database monitoring rules for anomalous query patterns
  • Policy enforcement requiring prepared statements and approved database access libraries
  • Review of database logs for unexpected query structures, enumeration behavior, or excessive errors

Frequently asked

questions

It may be remotely exploitable when the affected registration handler is exposed through a reachable web application endpoint and accepts attacker-controlled input.

Not necessarily. If the registration functionality is publicly accessible, an attacker may not need an account; deployment-specific access controls determine the actual requirement.

Replace dynamically constructed SQL with parameterized queries or prepared statements, then apply appropriate input validation and least-privilege database permissions.

Establish secure database access standards, prohibit unsafe query construction in code review and CI checks, use automated analysis, and monitor database activity for anomalous statements.
