Understanding the Weakness (CWE)
Confidentiality
Technical Impact: Read Application Data
At a minimum, attackers can garner information from query strings that can be utilized in escalating their method of attack, such as information about the internal workings of the application or database column names. Successful exploitation of query string parameter vulnerabilities could lead to an attacker impersonating a legitimate user, obtaining proprietary data, or simply executing actions not intended by the application developers. Examples of sensitive information may include secrets such as session identifiers, passwords, access tokens, or API keys; Personally Identifiable Information (PII) such as email addresses or phone numbers; records or logs of private activities; communications that are expected to be private; etc. Successful exploitation of query string parameter vulnerabilities could lead to an attacker impersonating a legitimate user, obtaining proprietary data, or simply executing actions not intended by the application developers.
