Nama: Improper Verification of Source of a Communication Channel

The product establishes a communication channel to handle an incoming request that has been initiated by an actor, but it does not properly verify that the request is coming from the expected origin.

Informasi Umum

Mode Pengenalan

Architecture and Design
Implementation : REALIZATION: This weakness is caused during implementation of an architectural security tactic.

Konsekuensi Umum

Cakupan Dampak Kemungkinan
Access Control
Other
Gain Privileges or Assume Identity, Varies by Context, Bypass Protection Mechanism

Catatan: An attacker from an untrusted origin could successfully establish a communication channel. The attacker could then gain privileges and access unexpected functionality that was only intended for trusted sources.

Catatan Pemetaan Kerentanan

Justifikasi : This CWE entry is at the Base level of abstraction, which is a preferred level of abstraction for mapping to the root causes of vulnerabilities.
Komentar : Carefully read both the name and description to ensure that this mapping is an appropriate fit. Do not try to 'force' a mapping to a lower-level Base/Variant simply to comply with this preferred level of abstraction.

Pola Serangan Terkait

CAPEC ID Nama Pola Serangan
CAPEC-500 WebView Injection
An adversary, through a previously installed malicious application, injects code into the context of a web page displayed by a WebView component. Through the injected code, an adversary is able to manipulate the DOM tree and cookies of the page, expose sensitive information, and can launch attacks against the web application from within the web page.
CAPEC-594 Traffic Injection
An adversary injects traffic into the target's network connection. The adversary is therefore able to degrade or disrupt the connection, and potentially modify the content. This is not a flooding attack, as the adversary is not focusing on exhausting resources. Instead, the adversary is crafting a specific input to affect the system in a particular way.
CAPEC-595 Connection Reset
In this attack pattern, an adversary injects a connection reset packet to one or both ends of a target's connection. The attacker is therefore able to have the target and/or the destination server sever the connection without having to directly filter the traffic between them.
CAPEC-596 TCP RST Injection
An adversary injects one or more TCP RST packets to a target after the target has made a HTTP GET request. The goal of this attack is to have the target and/or destination web server terminate the TCP connection.

Catatan

While many access control issues involve authenticating the user, this weakness is more about authenticating the actual source of the communication channel itself; there might not be any "user" in such cases.
