HawkScan Test Info for PII Disclosure

PII Disclosure


Plugin Id: 10062 | CWE: 359


To remediate the vulnerability of PII Disclosure, the following steps can be taken:

  1. Data Encryption: Implement encryption techniques to protect sensitive data such as credit card numbers (CC), social security numbers (SSN), and other personally identifiable information (PII). This can be achieved by using strong encryption algorithms and securely managing encryption keys.

  2. Secure Transmission: Ensure that all data transmissions, especially those containing PII, are encrypted using secure protocols such as HTTPS. This prevents unauthorized access to sensitive information during transit.

  3. Access Control: Implement strict access controls to limit the exposure of PII. Only authorized personnel should have access to sensitive data, and access should be granted on a need-to-know basis. Regularly review and update access privileges to minimize the risk of unauthorized disclosure.

  4. Data Masking: Implement data masking techniques to hide sensitive information when it is not required for processing or display. This can involve replacing sensitive data with fictional or obfuscated values, while still maintaining the integrity of the application’s functionality.

  5. Secure Development Practices: Follow secure coding practices and conduct regular security assessments to identify and address any vulnerabilities in the application. This includes input validation, output encoding, and proper error handling to prevent the disclosure of sensitive information.


The vulnerability of PII Disclosure refers to the situation where the response from an application contains Personally Identifiable Information (PII) such as credit card numbers (CC), social security numbers (SSN), and other sensitive data. This vulnerability can occur when proper security measures are not in place to protect the confidentiality of PII.


The risks associated with PII Disclosure vulnerability are:

  1. Identity Theft: If an attacker gains access to PII, they can use it for identity theft, financial fraud, or other malicious activities. This can result in significant financial losses and damage to the affected individuals.

  2. Legal and Compliance Issues: Failure to protect PII can lead to legal and regulatory consequences. Organizations may face fines, lawsuits, and reputational damage if they are found to be non-compliant with data protection regulations.

  3. Loss of Trust: PII disclosure can erode customer trust and confidence in an organization’s ability to protect their sensitive information. This can lead to a loss of business and damage to the organization’s reputation.

It is crucial for organizations to implement robust security measures to prevent PII Disclosure and protect the privacy of their users.
