• Modification or deletion of database records​

• Potential for complete compromise of the application’s integrity​

• Use of the compromised application as a pivot point for further attacks​

Mitigation Recommendations

• Input Validation: Implement strict input validation and sanitization for all user-supplied data, especially in the custmer_details parameter.​

• Use Prepared Statements: Adopt parameterized queries or prepared statements to prevent SQL injection.​

• Update Software: Check for and apply any available patches or updates provided by the vendor to address this vulnerability.​

• Restrict Database Permissions: Ensure the database user associated with the application has the minimum necessary privileges to limit potential damage.​

Conclusion

CVE-2023-49666 poses a significant threat to organizations using Billing Software v1.0. Due to the ease of exploitation and the potential impact, it’s crucial to implement the recommended mitigations promptly to secure affected systems.​
