Dettaglio CAPEC-38

This pattern of attack sees an adversary load a malicious resource into a program's standard path so that when a known command is executed then the system instead executes the malicious component. The adversary can either modify the search path a program uses, like a PATH variable or classpath, or they can manipulate resources on the path to point to their malicious components. J2EE applications and other component based applications that are built from multiple binaries can have very long list of dependencies to execute. If one of these libraries and/or references is controllable by the attacker then application controls can be circumvented by the attacker.

Prerequisiti

The attacker must be able to write to redirect search paths on the victim host.

Competenze richieste

To identify and execute against an over-privileged system interface

Mitigazioni

Design: Enforce principle of least privilege
Design: Ensure that the program's compound parts, including all system dependencies, classpath, path, and so on, are secured to the same or higher level assurance as the program
Implementation: Host integrity monitoring
