+ Summary

An adversary actively probes the target in a manner that is designed to solicit information that could be leveraged for malicious purposes. This is achieved by exploring the target via ordinary interactions for the purpose of gathering intelligence about the target, or by sending data that is syntactically invalid or non-standard in an attempt to produce a response that contains the desired data. As a result of these interactions, the adversary is able to obtain information from the target that aids the attacker in making inferences about its security, configuration, or potential vulnerabilities. Examplar exchanges with the target may trigger unhandled exceptions or verbose error messages that reveal information like stack traces, configuration information, path information, or database design. This type of attack also includes the manipulation of query strings in a URI to produce invalid SQL queries, or by trying alternative path values in the hope that the server will return useful information.

+ Attack Prerequisites
  • An adversary requires some way of interacting with the system.

+ Typical Severity


+ Typical Likelihood of Exploit

Likelihood: High

+ Resources Required

A tool, such as a MITM Proxy or a fuzzer, that is capable of generating and injecting custom inputs to be used in the attack.

+ Solutions and Mitigations

Minimize error/response output to only what is necessary for functional use or corrective language.

Remove potentially sensitive information that is not necessary for the application's functionality.

+ Attack Motivation-Consequences

Read application data
+ Other Notes

Large quantities of data is often moved from the target system to some other adversary controlled system. Data found on a target system might require extensive resources to be fully analyzed. Using these resources on the target system might enable a defender to detect the adversary. Additionally, proper analysis tools required might not be available on the target system.

This attack differs from Data Interception and other data collection attacks in that the attacker actively queries the target rather than simply watching for the target to reveal information.
